Stool Routine & Microscopic Examination Explained: How to Read Your Report, Parasites & Normal Range (India 2026)

स्टूल रूटीन टेस्ट: रिपोर्ट कैसे पढ़ें, परजीवी, सिस्ट और नॉर्मल रेंज — पूरी गाइड

The Stool Routine & Microscopic Examination (also called stool R/E, stool routine examination, or faecal examination) is one of the most commonly ordered tests in India — yet it is also one of the most frequently misunderstood. The report comes with 10–14 parameters covering the physical appearance of stool, chemical tests, and microscopic findings including pus cells, red blood cells, and parasite cysts. India has one of the world's highest burdens of intestinal parasitic infections — affecting an estimated 200–400 million people — and this test is the primary method for detecting them.

This guide explains every parameter in a stool routine report in simple English and Hindi — what each finding means, what counts as abnormal, which parasites are found in India and what their presence means, how to collect the sample correctly, and when treatment is needed. Doctors typically order stool routine alongside a CBC (to check for eosinophilia — a common sign of parasitic infection) and sometimes an ESR. For reading lab reports in general, see our beginner's guide to blood test reports.

स्टूल रूटीन और माइक्रोस्कोपिक जांच भारत में सबसे आम परीक्षणों में से एक है। यह पेट के परजीवी संक्रमण का पता लगाने की प्राथमिक विधि है। यह गाइड सरल अंग्रेजी और हिंदी में स्टूल रिपोर्ट को समझाती है।
Stool routine test explained — normal range report reading India 2026
Image 1: Stool Routine & Microscopic Examination tests 14 parameters across three categories — Physical examination (colour, consistency, odour, blood/mucus visible), Chemical tests (occult blood, pH, reducing substances), and Microscopic findings (pus cells, RBCs, epithelial cells, fat globules, parasite ova, cysts, trophozoites). Each category reveals different aspects of digestive and gut health.
200–400M Indians estimated to have intestinal parasitic infections — with hookworm, roundworm (Ascaris), pinworm, Giardia, and Entamoeba being the most prevalent.
14 parameters on a standard stool routine report — physical, chemical, and microscopic. Most reports from Indian labs cover all three sections.
Fresh < 2 hrs the critical rule for stool sample quality — parasites (especially trophozoites of Entamoeba and Giardia) die within hours outside the body. Sample must reach the lab within 2 hours.

What Is the Stool Routine Test? / स्टूल रूटीन टेस्ट क्या है?

The stool routine examination is a laboratory analysis of a fresh stool (faecal) sample that evaluates both the physical properties of the stool and its microscopic content. It is not a single test but a panel of observations: a technician first examines the sample with the naked eye (macroscopic examination), then performs a chemical test for occult blood and pH, and finally prepares a wet mount and stained smear for microscopic examination under high magnification. The microscopic examination is the most clinically valuable part — it can identify bacteria-related inflammatory changes (pus cells, RBCs), fat malabsorption, and crucially, the ova (eggs), cysts, and trophozoites of intestinal parasites.

स्टूल रूटीन जांच एक ताज़े स्टूल सैंपल का प्रयोगशाला विश्लेषण है जो स्टूल के भौतिक गुणों और माइक्रोस्कोपिक सामग्री का मूल्यांकन करता है। यह एकल परीक्षण नहीं बल्कि तीन श्रेणियों का पैनल है: मैक्रोस्कोपिक, रासायनिक, और माइक्रोस्कोपिक।
Why stool routine is still essential despite modern tests — a uniquely Indian perspective: In the era of PCR and molecular diagnostics, stool routine remains irreplaceable in India because it is inexpensive (typically ₹100–₹200), available at every lab including rural PHCs, requires no special equipment beyond a microscope, and provides direct morphological identification of parasites that PCR panels may not always be ordered for. Given India's high prevalence of polyparasitism (multiple simultaneous parasite infections in the same patient), stool routine provides a comprehensive single-sample overview. High eosinophils on a CBC are the classic blood test signal that prompts a stool routine to confirm intestinal parasites — particularly in children with recurrent abdominal pain, poor weight gain, or unexplained anaemia. भारत में स्टूल रूटीन क्यों अपरिहार्य है: यह सस्ता है, हर ग्रामीण PHC में उपलब्ध है, और परजीवी की प्रत्यक्ष रूपात्मक पहचान देता है। CBC पर उच्च ईोसिनोफिल = आंतों के परजीवी की पुष्टि के लिए स्टूल रूटीन।

All Parameters Explained — Physical, Chemical & Microscopic

Normal vs abnormal stool routine report India 2026
Image 2: Normal vs Abnormal stool routine report — Normal: brown, formed/soft, no mucus/blood, pus cells 0–5/hpf, RBCs nil, no parasites. Abnormal: pale/clay-coloured (biliary obstruction), black/tarry (upper GI bleed), blood-streaked (colitis/polyp), pus cells above 5/hpf (intestinal infection), parasite ova/cysts present.

The stool routine report is divided into three main sections. Understanding each parameter helps you interpret the report before seeing your doctor.

स्टूल रूटीन रिपोर्ट तीन मुख्य खंडों में विभाजित है। प्रत्येक पैरामीटर को समझना आपको डॉक्टर से मिलने से पहले रिपोर्ट को समझने में मदद करता है।
Parameter / पैरामीटर Normal / सामान्य Abnormal findings & meaning
PHYSICAL EXAMINATION / भौतिक जांच
Colour / रंग Brown Pale/clay/grey: biliary obstruction (blocked bile duct, jaundice — check LFT) · Black/tarry (melena): upper GI bleed (stomach/duodenum — urgent) · Bright red blood: lower GI bleed (colitis, haemorrhoids, rectal polyp) · Green: fast transit, antibiotic use, bile · Yellow: fat malabsorption, rotavirus diarrhoea in children
Consistency / स्थिरता Formed / Soft Watery/liquid: secretory or osmotic diarrhoea, cholera · Semi-formed/loose: mild infection, IBS · Hard/dry: constipation, dehydration · Ribbon-like: bowel narrowing, rectal stricture
Mucus / म्यूकस Absent Present: intestinal infection (bacterial, amoebic), inflammatory bowel disease, irritable bowel syndrome, rectal polyp. Mucus with blood = dysentery pattern — urgent stool culture needed.
Blood (macroscopic) / रक्त Absent Visible blood always abnormal. Bright red = lower GI. Dark/tarry = upper GI bleed. Always requires medical evaluation.
CHEMICAL TESTS / रासायनिक परीक्षण
Occult Blood (FOB) Negative Positive: hidden blood not visible to eye — peptic ulcer, gastric cancer, colorectal cancer, hookworm infection, IBD. Any positive FOB requires colonoscopy/endoscopy workup. False positives from red meat, iron tablets — patient must avoid these 3 days before test.
pH 6.5 – 7.5 Acidic pH (<6): carbohydrate malabsorption, lactose intolerance, fat malabsorption · Alkaline pH (>8): protein malabsorption, colitis, antibiotic-associated diarrhoea
Reducing Substances Absent Present in children: lactose intolerance, sucrase deficiency, malabsorption. This test is mainly performed in infants and young children with chronic diarrhoea.
MICROSCOPIC EXAMINATION / माइक्रोस्कोपिक जांच
Pus Cells (WBC) / पस सेल्स 0–5 per high-power field (hpf) 5–15/hpf: mild intestinal infection or inflammation · Above 15/hpf: significant bacterial infection, amoebic colitis, IBD · Very high (>50/hpf): dysentery — requires stool culture and sensitivity testing
Red Blood Cells (RBCs) / लाल रक्त कोशिकाएं Nil (absent) Any RBCs abnormal. Amoebic dysentery (RBCs + macrophages containing RBCs = pathognomonic), bacterial colitis, IBD, hookworm, rectal cancer. Always investigate RBCs in stool.
Epithelial Cells Few (occasional) Increased numbers indicate intestinal wall irritation or inflammation — seen in IBD, colitis, bacterial infection, and bowel cancer.
Fat Globules Absent / Occasional Increased fat (steatorrhoea): fat malabsorption — pancreatic insufficiency, coeliac disease, Crohn's disease, giardiasis (fat malabsorption is a classic feature of Giardia). Stool appears greasy and frothy.
Parasite Ova / Cysts / Trophozoites Not seen Any parasite finding is significant. Identified by species — see parasite section below. Trophozoites (active forms) die quickly outside body — fresh sample within 2 hours is essential.
Yeast Cells Absent Candida overgrowth — after prolonged antibiotics, in immunosuppressed patients, poorly controlled diabetes. Usually clinical significance depends on quantity and patient context.

Common Parasites Found in India / भारत में पाए जाने वाले परजीवी

India's intestinal parasite burden is among the highest globally — driven by poor sanitation, contaminated water supply, open defecation in rural areas, and consumption of unwashed raw produce. The stool routine identifies parasites by the presence of their ova (eggs), cysts (dormant infective forms), or trophozoites (active feeding forms). Each parasite has a characteristic morphology recognisable to an experienced microscopist.

Entamoeba histolytica — Amoebic dysentery एंटअमीबा हिस्टोलिटिका — अमीबिक पेचिश

The most clinically significant intestinal parasite in India — the cause of amoebic dysentery and amoebic liver abscess. Stool report shows: cysts (4-nucleated quadrinucleate cysts — the infective form found in chronic carriers) or trophozoites (identified by ingested RBCs inside them — pathognomonic of pathogenic E. histolytica vs the non-pathogenic E. dispar). Symptoms: dysentery (blood and mucus in stool), abdominal cramps. Treatment: metronidazole + diloxanide furoate. Trophozoites die rapidly — sample must reach lab within 30–60 minutes for trophozoite identification.

Giardia lamblia — Giardiasis जिआर्डिया — गियार्डियासिस

A flagellate protozoan — the most common intestinal protozoan globally and very prevalent in India. Classic presentation: frothy, foul-smelling, non-bloody diarrhoea; bloating; excessive flatulence; fat malabsorption causing greasy stools; and weight loss in children. Stool report shows pear-shaped or oval cysts with 2 or 4 nuclei (infective form in formed stools) or trophozoites with distinctive "owl-face" appearance (in liquid stools). Fat globules on microscopy are a clue — Giardia causes significant fat malabsorption. Treatment: metronidazole or tinidazole. Check B12 and folate in chronic Giardia — malabsorption can deplete both.

Ascaris lumbricoides — Roundworm राउंडवर्म — गोल कृमि

The most common soil-transmitted helminth in India — estimated to infect over 100 million Indians. Stool report shows large oval eggs (60×45 µm) with thick mammillated outer coat — immediately recognisable. Light infections: asymptomatic or mild abdominal discomfort. Heavy infections: malnutrition, intestinal obstruction (especially dangerous in children — can cause surgical emergency), biliary ascariasis (worms migrating into bile duct — severe right upper abdominal pain). Also causes eosinophilia on CBC (Löffler's syndrome during larval migration through lungs). Treatment: albendazole (400 mg single dose) or mebendazole.

Hookworm — Ancylostoma & Necator हुकवर्म — अंकुश कृमि

The leading cause of iron-deficiency anaemia from parasitic infection in India — hookworms attach to the intestinal wall and suck blood, causing chronic occult blood loss. Stool report shows characteristic oval thin-shelled eggs, often with an early morula (embryo) visible inside. Occult blood test typically positive. CBC shows significant eosinophilia and iron-deficiency anaemia (low Hb, low MCV, low ferritin — check iron studies). Transmitted through bare feet on contaminated soil. Treatment: albendazole 400 mg for 3 days; iron supplementation for anaemia correction.

Enterobius vermicularis — Pinworm / Threadworm पिनवर्म / धागा कृमि

The most common helminth infection in Indian children. Female worms migrate to the perianal area at night to lay eggs — causing intense nocturnal perianal itching (the cardinal symptom). Eggs are rarely found in routine stool — they are laid perianally. Diagnosis requires a scotch tape test (sticky tape applied to perianal area in the morning and examined microscopically). Oval, flat on one side, contain a larva. Treatment: albendazole or mebendazole — entire family must be treated simultaneously to prevent reinfection.

Trichuris trichiura & other helminths व्हिपवर्म और अन्य

Trichuris trichiura (whipworm) is common in Indian children — eggs are barrel-shaped with polar plugs, very distinctive. Causes rectal prolapse in heavy infections. Strongyloides stercoralis is a unique helminth in that it can multiply inside the human host (autoinfection) — dangerous in immunosuppressed patients where it causes hyperinfection syndrome. Stool shows rhabditiform larvae (not eggs). Taenia species (tapeworms from undercooked pork or beef) — gravid proglottids or eggs in stool. Cryptosporidium and Cyclospora are coccidian parasites causing watery diarrhoea — require modified Ziehl-Neelsen acid-fast staining for detection; not visible on standard stool routine.


Reading Your Report — Normal vs Abnormal Summary

Most stool routine reports use standardised terminology. The following combinations of findings are the most commonly encountered and clinically important patterns in India:

अधिकांश स्टूल रूटीन रिपोर्ट मानकीकृत शब्दावली का उपयोग करती हैं। निम्नलिखित संयोजन भारत में सबसे अधिक सामना किए जाने वाले और नैदानिक रूप से महत्वपूर्ण पैटर्न हैं।
Dysentery pattern — blood + mucus + pus cells पेचिश पैटर्न

Blood and mucus in stool (macroscopic or microscopic) combined with elevated pus cells (above 10–20/hpf) = dysentery. Requires urgent stool culture to distinguish amoebic (Entamoeba histolytica — macrophages with ingested RBCs) from bacterial dysentery (Shigella, Salmonella, Campylobacter — no macrophages). Treatment differs: amoebic dysentery requires metronidazole; bacterial dysentery requires specific antibiotics based on culture sensitivity. Never treat dysentery with antidiarrhoeal drugs alone.

Parasite detected — ova / cysts present परजीवी पाया गया

Any parasite finding is clinically significant and requires treatment. The specific parasite identified determines the drug: Giardia/Entamoeba → metronidazole/tinidazole; Ascaris/hookworm/pinworm/Trichuris → albendazole (400 mg single dose for Ascaris; 3 days for hookworm). CBC should be checked for eosinophilia. Iron studies for hookworm-associated anaemia. Three consecutive daily stool samples are recommended for definitive parasite exclusion — a single negative sample does not rule out infestation.

Occult blood positive — no visible blood गुप्त रक्त पॉजिटिव

Positive FOB (Faecal Occult Blood) with no visibly abnormal stool is a red flag for: peptic/duodenal ulcer, gastric cancer or colorectal cancer (FOB is a cancer screening test), hookworm infection, IBD, NSAID-induced gastric erosions. Any positive FOB in a patient above 40 with no obvious cause (diet/medications) mandates upper GI endoscopy and/or colonoscopy. Do not dismiss positive occult blood as insignificant without investigation.

Fat globules present — malabsorption pattern वसा कुअवशोषण

Increased fat globules in stool (steatorrhoea) indicate fat malabsorption — key causes: Giardia infection (fat malabsorption is a hallmark of chronic giardiasis), chronic pancreatitis or pancreatic insufficiency, coeliac disease (gluten intolerance — very common in north India), and Crohn's disease. Patient typically notices greasy, frothy, pale, difficult-to-flush stools. Malabsorption workup should include B12, folate, iron, calcium, and Vitamin D levels.


How to Collect the Stool Sample Correctly / सैंपल कैसे लें?

How to collect stool sample guide India 2026
Image 3: Correct stool sample collection for routine examination — use the lab-provided sterile container, collect a small amount (1–2 teaspoons) from multiple areas of the sample, avoid urine contamination, label with name and time of collection, and transport to the lab within 1–2 hours. Trophozoites (active parasite forms) die within 30–60 minutes — delay in transport causes false negative results.

The stool sample is the most important variable in stool routine testing — an incorrectly collected or delayed sample is one of the most common causes of false negative parasite results in Indian labs. Following these steps ensures the most reliable result:

स्टूल रूटीन परीक्षण में सैंपल सबसे महत्वपूर्ण चर है — गलत तरीके से एकत्र या विलंबित सैंपल भारतीय लैब में झूठे नकारात्मक परजीवी परिणामों का सबसे आम कारण है।
Use a sterile lab-provided container बाँझ कंटेनर का उपयोग करें

Always use the wide-mouthed sterile plastic container provided by the laboratory — never a used bottle, polythene bag, or newspaper. The container must be clean, dry, and free from any cleaning agents. Many labs provide a small spatula attached to the lid for sample collection. Fill the container with a small amount of stool — approximately 1–2 teaspoons is sufficient. Seal the lid tightly immediately after collection.

Collect from multiple areas — avoid urine contamination कई जगहों से एकत्र करें

Parasites are not uniformly distributed throughout the stool — collect small amounts from different parts of the sample (surface, centre, any visible mucus or blood-streaked areas). This significantly improves the chance of detecting parasites. Avoid urine contamination — this can dilute or alter the sample and interfere with microscopic examination. Do not collect from toilet water. Pass stool on a clean dry surface (plate, plastic sheet) before collection.

Transport within 2 hours — the critical rule 2 घंटे के भीतर पहुंचाएं — महत्वपूर्ण नियम

The freshness of the sample is the single most important factor for accurate parasite detection. Trophozoites (active forms) of Entamoeba histolytica and Giardia lamblia — the most pathogenic parasites — survive only 30–60 minutes outside the body at room temperature. Cysts survive longer (hours to days) but are better detected in fresh samples. For occult blood testing, the sample must not be contaminated with menstrual blood, urine, or toilet water. If same-day transport is not possible, refrigerate at 4°C (do NOT freeze) and deliver within 24 hours — but trophozoite detection will not be possible.

When to collect — and what to avoid beforehand कब और क्या से बचें

For occult blood testing: avoid red meat (mutton, beef), iron tablets, aspirin/NSAIDs, and vitamin C supplements for at least 3 days before the test — these can cause false positive or false negative results. For parasite detection: the morning sample (first stool of the day) is preferred — higher parasite concentration. Avoid taking laxatives or antacids for 48–72 hours before the test. If you are on metronidazole or other anti-parasitics, delay the stool routine by at least 1 week after completing treatment — the drugs suppress parasites temporarily and can cause false negative results.


When Is the Stool Routine Test Ordered?

The stool routine is one of the most versatile diagnostic tests in Indian primary care — ordered across a wide range of clinical presentations where gastrointestinal symptoms or gut-related systemic signs are present.

स्टूल रूटीन भारतीय प्राथमिक देखभाल में सबसे बहुमुखी नैदानिक परीक्षणों में से एक है।
Diarrhoea — acute and chronic दस्त — तीव्र और पुराना

The most common indication. Acute diarrhoea (less than 2 weeks): stool routine + culture to identify bacterial, viral, or parasitic cause. Chronic diarrhoea (more than 4 weeks): stool routine to look for Giardia, Entamoeba, Cryptosporidium, Strongyloides; fat globules for malabsorption. Diarrhoea with blood (dysentery) — pus cells and RBCs on stool routine are the first step before culture.

Abdominal pain & recurrent symptoms in children पेट दर्द और बच्चों में बार-बार लक्षण

Recurrent abdominal pain, poor weight gain, failure to thrive, and unexplained anaemia in Indian children should prompt stool routine to rule out parasitic infestation — the most common treatable cause of these symptoms in paediatric India. High eosinophils on the child's CBC are the blood-test signal to order stool routine.

Screening — annual deworming assessment वार्षिक डीवर्मिंग मूल्यांकन

India's National Deworming Day programme targets school-age children — but stool routine for parasite screening is also appropriate for adults in rural and semi-urban India who regularly eat raw/undercooked food, have poor sanitation access, or work in agriculture (barefoot soil contact = hookworm risk). A stool routine before and after deworming confirms treatment success.

Colorectal cancer screening (FOB test) कोलोरेक्टल कैंसर स्क्रीनिंग

The Faecal Occult Blood (FOB) test in the stool routine is an important colorectal cancer screening tool. Current guidelines recommend annual FOB testing for adults above 45 with a family history of colorectal cancer, unexplained iron-deficiency anaemia, or rectal bleeding. A positive FOB in any adult above 40 without obvious explanation mandates colonoscopy. Early colorectal cancer detected by FOB has an excellent prognosis.

 Gut Health Support After Deworming — Multivitamin with Probiotics

Intestinal parasite infections — particularly hookworm and Giardia — cause significant nutritional depletion: iron, B12, folate, Vitamin D, and protein absorption are all impaired during active infestation and for weeks afterward. After completing deworming treatment (albendazole/metronidazole), replenishing these nutrients and restoring gut flora with probiotics supports faster recovery and prevents rebound symptoms. A good multivitamin with probiotics and omega-3s helps rebuild gut integrity and immunity. Always consult your doctor before starting any supplement — some nutrients may need higher therapeutic doses if blood tests confirm deficiency (e.g., severe iron deficiency anaemia from hookworm).

Carbamide Forte Multivitamin for Men with Probiotics and Salmon Oil India

Carbamide Forte Multivitamin for Men with Probiotics & Salmon Oil

Comprehensive multivitamin combining essential micronutrients, probiotics (for gut microbiome restoration after antiparasitic treatment), and omega-3 from salmon oil.

Frequently Asked Questions / अक्सर पूछे जाने वाले सवाल

What does "pus cells 10–15/hpf" mean on a stool routine report?

Pus cells (white blood cells / WBCs) in stool indicate intestinal inflammation or infection. Normal is 0–5 pus cells per high-power field (hpf). A count of 10–15/hpf indicates a moderate degree of intestinal inflammation — most commonly caused by bacterial gastroenteritis (Shigella, Salmonella, E. coli, Campylobacter), amoebic colitis (Entamoeba histolytica), or early inflammatory bowel disease. This level of pus cells usually requires medical attention and often a stool culture to identify the specific bacterium or confirm the parasitic cause. Very high pus cell counts (above 30–50/hpf), especially with visible blood and mucus, indicate dysentery requiring urgent treatment. Do not self-medicate — bacterial and amoebic dysentery require different antibiotics/antiparasitics.

उत्तर: 10–15/hpf पस सेल्स = आंत में मध्यम सूजन या संक्रमण। अधिकांशतः जीवाणु गैस्ट्रोएंटेराइटिस या अमीबिक कोलाइटिस। स्टूल कल्चर और उचित उपचार की जरूरत है।
Stool routine shows "E. histolytica cysts found." Does this mean I have amoebic dysentery?

Not necessarily — and this is an important distinction. Entamoeba histolytica cysts in the stool can indicate either: active infection causing disease (amoebic dysentery or amoebic liver abscess), or asymptomatic carriage (the person is a carrier who passes cysts but has no symptoms). In addition, the non-pathogenic species Entamoeba dispar is morphologically identical to E. histolytica cysts on standard light microscopy — the two cannot be distinguished by routine stool examination alone. The key clinical discriminator is symptoms: if you have bloody diarrhoea, mucus, abdominal cramps, or a tender liver — this is likely invasive E. histolytica and requires treatment with metronidazole + diloxanide furoate. If you are asymptomatic with only cysts found — diloxanide furoate alone is used for cyst passers. If trophozoites containing ingested RBCs are seen — this is definitively pathogenic E. histolytica and treatment is mandatory regardless of symptoms.

उत्तर: E. histolytica सिस्ट = सक्रिय संक्रमण या स्पर्शोन्मुख वाहक। गैर-रोगजनक E. dispar दिखने में समान है। मुख्य अंतर: लक्षण। RBC वाले ट्रोफोज़ोइट = निश्चित रूप से रोगजनक — तुरंत उपचार।
What is the correct way to collect a stool sample for routine examination?

Use the sterile wide-mouthed container provided by the laboratory — never a household container, bag, or cup. Pass stool on a clean, dry surface first. Collect a small amount (approximately 1–2 teaspoons, roughly 5–10 grams) from different parts of the sample using the attached spatula — especially from any areas with visible mucus, blood, or abnormal appearance. Seal the container tightly and label it with your name and the exact time of collection. Transport to the laboratory within 1–2 hours at room temperature — do not refrigerate unless transport will take longer, and never freeze. For occult blood testing (FOB): avoid red meat (mutton, beef, liver), iron tablets, aspirin, and vitamin C for 3 days before collection. For best parasite detection: collect the first morning stool, transport immediately, and repeat on 3 consecutive days if the first sample is negative and clinical suspicion remains.

उत्तर: लैब-प्रदत्त बाँझ कंटेनर का उपयोग करें। विभिन्न क्षेत्रों से 5–10 ग्राम एकत्र करें। 2 घंटे के भीतर लैब पहुंचाएं। FOB के लिए: 3 दिन पहले से लाल मांस और आयरन की गोलियां बंद करें।
Stool routine was normal but I still have diarrhoea and abdominal symptoms. What next?

A normal stool routine does not definitively rule out all causes of diarrhoea and abdominal symptoms. Several important conditions can give a normal stool routine: Cryptosporidium and Cyclospora (require special acid-fast staining, not done in standard routine), Strongyloides (larvae may be missed without concentration techniques), early or mild Giardia (sensitivity of a single stool exam for Giardia is only 50–75% — three consecutive day samples are needed), viral gastroenteritis (rotavirus, norovirus — not detected by stool routine), irritable bowel syndrome, small intestinal bacterial overgrowth (SIBO), lactose intolerance, and functional dyspepsia. If symptoms persist, the following additional investigations are recommended: repeat stool routine on 2 more consecutive days; stool culture (for bacterial pathogens not visible on routine microscopy); stool ELISA for Giardia antigen and Cryptosporidium antigen; and if chronic — colonoscopy for IBD. A rising CBC eosinophil count alongside persistent symptoms is a strong indicator to pursue parasite testing with concentration methods.

उत्तर: सामान्य स्टूल रूटीन सभी कारणों को नकारता नहीं। Cryptosporidium, Cyclospora, SIBO, IBS — ये मानक रूटीन पर नहीं दिखते। अगले चरण: 3 दिन लगातार रूटीन, स्टूल कल्चर, Giardia एंटीजन ELISA, और यदि पुराना — कोलोनोस्कोपी।
My child's stool shows Ascaris (roundworm). Is this dangerous?

Ascaris lumbricoides (roundworm) is the most common worm infection in Indian children and is treatable with a single dose of albendazole (400 mg) or mebendazole. Light infections (few worms) cause minimal symptoms — mild abdominal discomfort, occasional vomiting. However, heavy Ascaris infection in children is potentially serious: massive worm burden can cause intestinal obstruction (a surgical emergency — most common cause of intestinal obstruction from parasites in Indian children), biliary ascariasis (worms entering the bile duct causing severe right upper quadrant pain, jaundice), and pancreatic ascariasis. Chronic infection causes malnutrition, impaired cognitive development, and anaemia. After treating with albendazole, repeat the stool routine in 2–4 weeks to confirm clearance. Also check CBC for eosinophilia (should normalise after treatment) and haemoglobin for any associated anaemia.

उत्तर: Ascaris (राउंडवर्म) एकल खुराक एल्बेंडाजोल (400 mg) से उपचारयोग्य है। हल्का संक्रमण न्यूनतम लक्षण। भारी संक्रमण = आंत्र अवरोध (शल्य आपातकाल), पित्त नली Ascaris — गंभीर। उपचार के 2–4 सप्ताह बाद स्टूल रूटीन दोहराएं।
Is fasting required before a stool routine test?

No — fasting is not required for a stool routine examination. Stool composition and parasite detection are not significantly affected by recent food intake. You can eat and drink normally before collecting the sample. However, there are important dietary restrictions specifically for the Faecal Occult Blood (FOB) component of the stool routine: avoid red meat (mutton, beef, liver), iron tablets, aspirin/NSAIDs, and high-dose Vitamin C supplements for at least 3 days before the test — these cause false positive or false negative FOB results. Additionally, avoid antiparasitic drugs (metronidazole, albendazole) for at least 1–2 weeks before the test as they suppress parasites and cause false negative results. Collect the first morning sample for the highest yield, and transport to the lab within 2 hours without refrigeration.

उत्तर: नहीं — स्टूल रूटीन के लिए उपवास आवश्यक नहीं। FOB के लिए: 3 दिन पहले लाल मांस, आयरन, और NSAIDs से बचें। एंटीपैरासिटिक दवाओं के 1–2 सप्ताह बाद टेस्ट करवाएं।
