H. Pylori टेस्ट: नॉर्मल रेंज, पॉजिटिव रिजल्ट, लक्षण और इलाज की पूरी गाइड
In India, we often dismiss stomach burning, bloating, and gas as "simple acidity" caused by spicy food. However, Helicobacter pylori (H. pylori) — a bacteria that lives in the stomach lining — infects an estimated 50–60% of the Indian population and is the leading cause of chronic gastritis, stomach ulcers, and peptic ulcer disease. Left untreated, H. pylori is classified as a Group I carcinogen by the WHO (IARC) — meaning it directly causes stomach cancer.
This guide explains the H. pylori test in simple English and Hindi — the different test types available in India, how to read your result, what a positive result means, and how it is treated. For reading lab reports in general, see our beginner's guide to blood test reports.
भारत में 50–60% आबादी H. Pylori बैक्टीरिया से संक्रमित है — यह पेट के अल्सर और कैंसर का मुख्य कारण है। यह गाइड H. Pylori टेस्ट के प्रकार, रिपोर्ट पढ़ने का तरीका और इलाज को सरल भाषा में समझाती है। Table of Contents / विषय सूची
What Is H. Pylori? / H. Pylori क्या है?
Helicobacter pylori is a gram-negative spiral bacterium that colonises the stomach lining (gastric mucosa). Unlike most bacteria that cannot survive in the acidic stomach environment, H. pylori has evolved a clever mechanism — it produces an enzyme called urease, which converts urea (present naturally in the stomach) into ammonia. This ammonia neutralises the surrounding acid, creating a protective bubble that allows H. pylori to live in the mucus layer of the stomach wall.
Over time, the ammonia and other H. pylori toxins damage the protective mucus layer, leading to chronic gastritis (stomach lining inflammation), peptic ulcers (open sores in the stomach or duodenum), and in a small percentage of long-term carriers, stomach cancer. For more on how H. pylori causes these effects, see Mayo Clinic's overview.
H. Pylori एक बैक्टीरिया है जो पेट की अंदरूनी परत (गैस्ट्रिक म्यूकोसा) में रहता है। यह urease एंजाइम बनाकर एसिड को बेअसर करता है। समय के साथ यह सुरक्षात्मक म्यूकस परत को नुकसान पहुंचाता है, जिससे जठरशोथ (gastritis), पेप्टिक अल्सर, और दुर्लभ मामलों में पेट का कैंसर हो सकता है।Symptoms of H. Pylori Infection / H. Pylori के लक्षण
Most people infected with H. pylori have no symptoms at all — the infection is discovered incidentally on testing. When symptoms do occur, they can be easily confused with general acidity or indigestion, which is why so many Indian patients self-medicate with antacids for years without addressing the underlying bacterial infection.
H. pylori से संक्रमित अधिकांश लोगों में कोई लक्षण नहीं होते। जब लक्षण होते हैं, तो उन्हें सामान्य एसिडिटी से भ्रमित किया जा सकता है।The hallmark symptom. A gnawing or burning pain in the upper abdomen (epigastric region) that is characteristically worse on an empty stomach and temporarily relieved by eating or antacids. This pattern distinguishes H. pylori ulcer pain from acid reflux (which typically worsens after eating). Morning burning before breakfast is a classic pattern.
Feeling full immediately after a small meal (early satiety), excessive gas and burping throughout the day, and persistent nausea especially in the mornings. These symptoms overlap significantly with other gastric conditions — which is why testing rather than empirical treatment is always recommended.
Black or tarry stools (melena — digested blood from an upper GI bleed), coffee-ground vomit (blood mixed with stomach acid), and sudden severe stabbing abdominal pain (perforation) are medical emergencies indicating active ulcer complications. These require immediate emergency care — do not wait for a blood test.
Chronic low-level blood loss from a small peptic ulcer can cause iron-deficiency anaemia — presenting as fatigue, breathlessness, and pallor. H. pylori also causes unexplained weight loss and loss of appetite. Any patient with unexplained iron-deficiency anaemia should have H. pylori testing alongside a CBC.
Types of H. Pylori Tests Available in India
There are four main types of H. pylori tests used in India — each with different accuracy, cost, and clinical use. Choosing the right test at the right time significantly impacts how useful the result is.
भारत में H. pylori के चार मुख्य प्रकार के टेस्ट हैं — प्रत्येक की अलग सटीकता, लागत और नैदानिक उपयोग है।| Test Type | What it detects | Best used for | Accuracy | Cost in India |
|---|---|---|---|---|
| H. Pylori IgG (Blood antibody) ब्लड टेस्ट |
IgG antibodies to H. pylori — past or present exposure | Initial screening; cannot distinguish active from past infection | ~85% (moderate specificity) | ₹300–700 |
| H. Pylori Stool Antigen Test स्टूल टेस्ट |
H. pylori antigens shed in stool — active infection | Active infection diagnosis; test-of-cure after treatment | ~94% sensitivity, ~97% specificity | ₹600–1,200 |
| Urea Breath Test (UBT) यूरिया ब्रीथ टेस्ट |
CO₂ released by H. pylori urease — active infection only | Best for active infection; gold standard for test-of-cure after treatment | >95% sensitivity and specificity | ₹800–2,000 |
| Endoscopy with Biopsy एंडोस्कोपी |
Direct visualisation + histology, CLO test, culture | When endoscopy is needed anyway (ulcer, cancer suspicion, treatment failure) | Nearly 100% with culture | ₹3,000–8,000+ |
Normal Range & Reading Your Report / नॉर्मल रेंज
The H. pylori IgG blood test reports an "Index Value" (not a simple positive/negative in all labs — some report it as U/mL or as a ratio). Here is how to interpret the standard index value:
H. pylori IgG ब्लड टेस्ट एक "इंडेक्स वैल्यू" रिपोर्ट करता है। यहां बताया गया है कि मानक इंडेक्स वैल्यू की व्याख्या कैसे करें:| Index Value / इंडेक्स वैल्यू | Result | Interpretation |
|---|---|---|
| < 0.9 | Negative / नेगेटिव | No detectable IgG antibodies. No evidence of current or past H. pylori infection. If symptoms persist, consider other gastric causes or order UBT/stool antigen for higher accuracy. |
| 0.9 – 1.1 | Equivocal / संदेहास्पद | Borderline result — neither clearly positive nor negative. Retest after 2–4 weeks, or confirm with UBT or stool antigen test. Do not start treatment based on an equivocal result alone. |
| > 1.1 | Positive / पॉजिटिव | H. pylori antibodies detected. Indicates current or past infection. In a symptomatic patient with no prior treatment — treat. In a previously treated patient — confirm active infection with UBT before re-treating. |
Treatment — Triple Therapy / इलाज
H. pylori is treated with a combination of antibiotics and a proton pump inhibitor (PPI). This is called "Triple Therapy" — and when followed correctly, it eradicates the bacteria in 85–90% of patients. Do not start any antibiotic course for H. pylori without a doctor's prescription.
H. pylori का इलाज एंटीबायोटिक्स और PPI के संयोजन से किया जाता है — इसे "ट्रिपल थेरेपी" कहते हैं। सही तरीके से पालन करने पर यह 85–90% रोगियों में बैक्टीरिया को नष्ट कर देता है।The standard first-line treatment in India: PPI (Pantoprazole or Omeprazole) + Clarithromycin + Amoxicillin, taken twice daily for 14 days. The PPI reduces stomach acid to create an environment where antibiotics work better. All three medicines must be taken together, at the same times, and for the full 14 days — stopping early is the most common reason treatment fails.
If standard triple therapy fails (first-line treatment failure), quadruple therapy is used: PPI + Bismuth + Metronidazole + Tetracycline for 10–14 days. In India, clarithromycin resistance in H. pylori is increasing — especially in urban populations with prior antibiotic exposure. Gastroenterologist referral is recommended for treatment failures.
A test-of-cure must be done at least 4 weeks after completing the antibiotic course. The best tests are the Urea Breath Test (UBT) or stool antigen test — not the IgG blood test, which stays positive for months after cure. Skipping the test-of-cure means you do not know if the bacteria was actually eliminated — which is important because untreated H. pylori carries ongoing cancer risk.
H. pylori antibiotic resistance is a serious and growing problem in India. Random self-prescription of clarithromycin or amoxicillin without culture sensitivity testing can create resistant strains that are then much harder to treat. India's antibiotic resistance burden — driven by over-the-counter antibiotic availability — makes doctor-guided H. pylori treatment essential.
Diet During H. Pylori Treatment / आहार
Diet does not treat H. pylori — only antibiotics can eradicate the bacteria. However, the right diet significantly reduces symptom severity, improves antibiotic tolerance, and helps the stomach lining heal faster during treatment.
आहार H. pylori का इलाज नहीं करता — केवल एंटीबायोटिक्स बैक्टीरिया को नष्ट कर सकती हैं। हालांकि, सही आहार लक्षणों की गंभीरता को काफी कम करता है और उपचार के दौरान पेट की परत को तेजी से ठीक होने में मदद करता है।Probiotics (curd / dahi): Lactobacillus-rich yoghurt may reduce H. pylori load and reduce antibiotic side effects — eat daily during treatment. Cooked vegetables: Lightly cooked low-fibre vegetables (bottle gourd, lauki, pumpkin). Dal: Well-cooked, not heavily spiced. Bananas: Coat the stomach lining. Boiled rice: Gentle on the stomach. Honey: Has mild antibacterial properties against H. pylori in lab studies. Eat small, frequent meals rather than two or three large ones.
Spicy masalas and chilli: Directly irritate the inflamed stomach lining. Fried and oily food: Slows gastric emptying, worsens bloating. Alcohol: Directly damages stomach mucosa and reduces antibiotic effectiveness. Tea and coffee on an empty stomach: Increase acid secretion. NSAIDs (ibuprofen, diclofenac, aspirin): Severely aggravate ulcers and can cause bleeding — avoid completely during H. pylori treatment. Raw onion and garlic in excess.

H. pylori निदान के साथ या बाद में ये जांचें अक्सर करवाई जाती हैं:Frequently Asked Questions / अक्सर पूछे जाने वाले सवाल
The H. pylori IgG blood test reports an Index Value. An index below 0.9 is Negative — no H. pylori antibodies detected. An index of 0.9 to 1.1 is Equivocal — borderline, repeat after 2–4 weeks or confirm with UBT. An index above 1.1 is Positive — H. pylori antibodies detected. However, a positive IgG does not confirm active infection — antibodies can persist for months to years after successful treatment. For confirming active infection, the Urea Breath Test (UBT) or stool antigen test is more reliable. Always check the reference range printed on your specific lab report, as some labs use different units.
उत्तर: 0.9 से कम = नेगेटिव। 0.9–1.1 = संदेहास्पद (2-4 सप्ताह बाद दोहराएं)। 1.1 से ऊपर = पॉजिटिव। IgG पॉजिटिव सक्रिय संक्रमण की पुष्टि नहीं करता — एंटीबॉडी इलाज के बाद महीनों तक रह सकती हैं।Yes — H. pylori is contagious and spreads primarily through the faecal-oral route: contaminated food, contaminated water, unwashed hands after using the toilet, and sharing utensils, drinking glasses, or food with an infected person. Saliva-to-saliva contact (kissing) may also transmit the bacteria. In India's household context — where food is often shared from a common plate and water quality is inconsistent — family clustering of H. pylori infection is common. If one family member is diagnosed, testing close contacts (particularly those sharing meals) is advisable. Handwashing before eating, drinking filtered or boiled water, and not sharing utensils are the most effective preventive measures.
उत्तर: हां — H. pylori मल-मौखिक मार्ग से फैलता है। दूषित भोजन, पानी, बिना धुले हाथ, या संक्रमित व्यक्ति के साथ बर्तन साझा करना। यदि एक परिवार के सदस्य को निदान हो, तो निकट संपर्कों की भी जांच करवाएं।Yes — H. pylori can be permanently eradicated with a 14-day Triple Therapy antibiotic course in approximately 85–90% of patients. Treatment consists of a PPI (Pantoprazole or Omeprazole) combined with two antibiotics (typically Clarithromycin and Amoxicillin). All three must be taken twice daily for the full 14 days — partial courses are a leading cause of treatment failure and antibiotic resistance. After completing treatment, a test-of-cure (Urea Breath Test or stool antigen test) must be done at least 4 weeks later to confirm eradication. Re-infection is possible — particularly in India where H. pylori is endemic in water and food — so preventive hygiene measures should be maintained after successful treatment.
उत्तर: हां — 14 दिनों की ट्रिपल थेरेपी से 85–90% रोगियों में H. pylori को स्थायी रूप से नष्ट किया जा सकता है। उपचार के कम से कम 4 सप्ताह बाद UBT या स्टूल एंटीजन टेस्ट से पुष्टि करें।Not necessarily — and this is one of the most important things to understand about the IgG blood test. IgG antibodies are a form of immune memory — your body keeps making them for months to years after the infection has been cleared. A positive IgG blood test after successful H. pylori treatment almost always reflects residual antibody, not active infection. To confirm whether the bacteria has been truly eradicated, only the Urea Breath Test (UBT) or stool antigen test should be used — and only at least 4 weeks after completing antibiotics. If UBT or stool antigen is negative after treatment, you are cured regardless of what the IgG blood test shows.
उत्तर: जरूरी नहीं — IgG एंटीबॉडी इलाज के बाद महीनों तक रहती हैं। इलाज के बाद सक्रिय संक्रमण की पुष्टि के लिए केवल UBT या स्टूल एंटीजन टेस्ट का उपयोग करें — कम से कम 4 सप्ताह बाद।Yes — H. pylori is classified as a Group I (definite) carcinogen by the WHO/IARC, meaning it is a proven cause of stomach (gastric) cancer. However, it is important to understand the actual risk: while H. pylori infection is very common (50–60% in India), only about 1–3% of infected people develop stomach cancer over their lifetime. The risk is highest in people with persistent untreated infection over decades, family history of gastric cancer, those who smoke, and those with specific atrophic gastritis patterns. H. pylori eradication with Triple Therapy significantly reduces the risk of gastric cancer — which is why early diagnosis and treatment is so important, even in asymptomatic people discovered incidentally.
उत्तर: हां — H. pylori को WHO ने Group I कार्सिनोजन के रूप में वर्गीकृत किया है। हालांकि, केवल लगभग 1–3% संक्रमित लोगों को पेट का कैंसर होता है। ट्रिपल थेरेपी से उन्मूलन कैंसर के जोखिम को काफी कम करता है।The Urea Breath Test is the most accurate non-invasive test for active H. pylori infection and the gold standard for confirming eradication after treatment. The test works by exploiting H. pylori's urease enzyme. You drink a small amount of a special liquid containing labelled urea (either carbon-13 or carbon-14). If H. pylori is present in your stomach, its urease enzyme breaks down the urea and releases labelled CO₂, which is absorbed into the blood and exhaled in your breath. You breathe into a collection bag, and the lab measures the labelled CO₂. The test takes about 30 minutes, requires 4 hours of fasting before, and must be done at least 4 weeks after stopping antibiotics and 2 weeks after stopping PPIs. No radiation exposure with the C-13 version — safe for children and pregnant women.
उत्तर: यूरिया ब्रीथ टेस्ट सबसे सटीक गैर-आक्रामक टेस्ट है। आप लेबल यूरिया का एक घोल पीते हैं; H. pylori का urease इसे तोड़ता है और लेबल CO₂ आपकी सांस में आती है। लगभग 30 मिनट में पूरा; एंटीबायोटिक्स बंद करने के 4 सप्ताह बाद और PPIs के 2 सप्ताह बाद करवाएं।During and after H. pylori antibiotic treatment, the gut microbiome is disrupted by the antibiotics. A good probiotic supplement with adequate CFU count can help restore gut flora balance, reduce antibiotic-associated side effects (diarrhoea, nausea), and improve treatment tolerance. Always consult your doctor before starting any supplement, and inform them about all medications you are taking.
