मलेरिया एंटीजन टेस्ट: पॉजिटिव vs नेगेटिव रिपोर्ट, Pf vs Pv मलेरिया और अगले कदम — पूरी गाइड
A high fever with chills, sweating, headache, and body aches in the monsoon season — and your doctor has ordered a malaria antigen test. The Malaria Rapid Diagnostic Test (RDT) or Malaria Antigen Test detects specific proteins produced by malaria parasites directly in your blood, giving a result in 15–30 minutes. It has largely replaced the older peripheral blood smear (PBS) as the first-line test for malaria in Indian clinics and laboratories — because it is fast, requires no microscope expertise, and accurately identifies both the species and severity of the infection.
Understanding your malaria test report is critical — not just whether it is positive or negative, but which species of Plasmodium is identified, because the treatment regimen, drug choice, and risk of complications differ entirely between P. falciparum (dangerous, can be fatal) and P. vivax (less immediately lethal but prone to relapse). This guide explains the malaria antigen test in simple English and Hindi. Doctors also check a CBC alongside malaria testing to assess platelet drop and anaemia — both important in malaria management. For reading lab reports in general, see our beginner's guide to blood test reports.

What Is the Malaria Antigen / RDT Test?
The Malaria Antigen Test (also called Malaria RDT — Rapid Diagnostic Test, or Malaria Card Test) is an immunochromatographic lateral flow assay that detects malaria parasite antigens directly in a fingerprick blood sample. Unlike the peripheral blood smear (which requires staining, a microscope, and an expert microscopist), the RDT can be performed by any trained healthcare worker and produces a result within 15–30 minutes — making it ideal for India's rural and periurban settings where laboratory infrastructure is limited.
The standard malaria RDT used in India (under the National Vector Borne Disease Control Programme — NVBDCP) detects two antigens simultaneously:
मलेरिया एंटीजन टेस्ट (RDT) एक इम्यूनोक्रोमैटोग्राफिक लेटरल फ्लो परख है जो उंगली की चुभन रक्त नमूने में सीधे मलेरिया परजीवी एंटीजन का पता लगाती है। कोई भी प्रशिक्षित स्वास्थ्यकर्मी इसे कर सकता है — माइक्रोस्कोपिस्ट की जरूरत नहीं।HRP-2 is a protein produced exclusively by Plasmodium falciparum trophozoites and gametocytes — making it highly specific for Pf malaria. The HRP-2 line on the test strip turns positive when significant numbers of Pf parasites are present. Critical limitation: HRP-2 persists in blood for up to 3–4 weeks after successful treatment — a positive HRP-2 line can represent cured past Pf malaria, not necessarily active infection. In areas of India with high endemicity, this persistence causes difficulties in re-diagnosis. Some Pf strains from certain Indian states (notably Odisha and Jharkhand) show HRP-2 gene deletion mutations — causing false negative RDT results despite active Pf infection.
pLDH (pan-malarial LDH) is produced by all four Plasmodium species — P. falciparum, P. vivax, P. malariae, and P. ovale — making it a pan-malaria marker. pLDH disappears rapidly from blood within 24–48 hours after parasite clearance with treatment — unlike HRP-2 which persists for weeks. This makes pLDH the better marker for confirming active (current) infection and monitoring treatment response. Species-specific pLDH bands can distinguish Pv from Pf on certain RDT platforms. A positive pLDH with negative HRP-2 suggests P. vivax or P. malariae infection.
Reading Your Malaria RDT Report — All Result Combinations
The standard malaria RDT strip has 3 zones — a Control (C) line that always appears if the test worked correctly, an HRP-2 (T1) line for P. falciparum, and a pLDH (T2) pan-malaria line for all species. Reading the result is based on which lines appear:
मानक मलेरिया RDT पट्टी में 3 क्षेत्र होते हैं — एक कंट्रोल (C) रेखा (हमेशा दिखनी चाहिए), एक HRP-2 (T1) रेखा P. falciparum के लिए, और एक pLDH (T2) पैन-मलेरिया रेखा। परिणाम इस आधार पर पढ़ा जाता है कि कौन सी रेखाएं दिखती हैं।| Control Line (C) | HRP-2 Line (T1) | pLDH Line (T2) | Result & Interpretation | Action |
|---|---|---|---|---|
| ✓ Present | Absent | Absent | NEGATIVE — No malaria antigens detected | Malaria unlikely but not excluded. If fever persists and suspicion is high, repeat in 24–48 hours or send for blood smear + PCR. |
| ✓ Present | ✓ Present | Absent | P. falciparum POSITIVE — HRP-2 only | Confirmed Pf malaria — or HRP-2 persistence from recently treated Pf. Confirm with pLDH or blood smear if recently treated. Start ACT immediately if clinically active. |
| ✓ Present | ✓ Present | ✓ Present | P. falciparum POSITIVE — both markers | Confirmed active Pf (pLDH confirms current infection, not past). Treat as uncomplicated or severe Pf per clinical state. Urgent hospitalisation if severe Pf features present. |
| ✓ Present | Absent | ✓ Present | NON-Pf MALARIA — P. vivax most likely | pLDH positive without HRP-2 = P. vivax (or rarely P. malariae / P. ovale). Start Pv treatment (chloroquine + primaquine). Check G6PD before primaquine. |
| Absent | Any | Any | INVALID — Test failed | No control line = the test did not work correctly. Discard and repeat with a new RDT kit. Never interpret an invalid result as negative. |
P. falciparum vs P. vivax — The Critical Difference
Knowing which species of malaria you have is as important as knowing whether you have malaria at all — because the dangers, complications, and treatment regimens differ completely between the two species responsible for 99% of Indian malaria cases.
कौन सी प्रजाति का मलेरिया है यह जानना उतना ही महत्वपूर्ण है जितना यह जानना कि मलेरिया है या नहीं — क्योंकि खतरे, जटिलताएं, और उपचार पूरी तरह अलग हैं।P. falciparum is responsible for approximately 50% of Indian malaria cases but nearly all malaria deaths. Pf parasites infect red blood cells of all ages (not just young RBCs), invade at very high density, produce cytoadhesion proteins that cause infected RBCs to stick to small blood vessels — causing severe malaria with multi-organ failure. Severe Pf malaria complications: cerebral malaria (coma, seizures), severe anaemia (haemoglobin below 5 g/dL), acute respiratory distress syndrome (ARDS), acute kidney injury (blackwater fever — haemoglobinuria), severe thrombocytopenia, hypoglycaemia, and metabolic acidosis. Falciparum malaria is a medical emergency — any suspected severe Pf requires immediate hospitalisation. Treatment: Artemisinin-based Combination Therapy (ACT) — Artemether-Lumefantrine or Artesunate-SP (as per NVBDCP guidelines). IV artesunate for severe malaria. Pf does NOT relapse — no liver dormancy stage.
P. vivax accounts for approximately 50% of Indian malaria and is dominant in north India, parts of Maharashtra, Gujarat, and Rajasthan. Pv is less immediately dangerous than Pf — but presents a unique challenge through relapse from hypnozoites (dormant liver-stage parasites) that can cause clinical malaria 3 weeks to 5 years after the initial infection, even after complete blood-stage clearance with chloroquine. Pv complications: severe anaemia (especially in repeated relapses), thrombocytopenia (platelet drop — similar to dengue; check CBC), splenomegaly (enlarged spleen from repeated infections), and rare severe Pv (becoming more recognised). Treatment: Chloroquine (blood stage) + Primaquine (liver stage — to kill hypnozoites and prevent relapse). G6PD testing mandatory before primaquine — primaquine causes life-threatening haemolysis in G6PD-deficient patients, and G6PD deficiency is common in India.
| Feature | P. falciparum (Pf) | P. vivax (Pv) |
|---|---|---|
| RDT marker | HRP-2 positive (+ pLDH) | pLDH positive, HRP-2 negative |
| Danger level | High — potentially fatal | Lower acutely — relapse risk |
| Severe malaria | Cerebral malaria, organ failure, ARDS, AKI | Rare — severe anaemia, splenomegaly |
| Relapse | None — no liver dormancy | Yes — hypnozoites cause relapse months to years later |
| Platelet drop | Common — thrombocytopenia | Common — thrombocytopenia |
| Blood-stage treatment | ACT (Artemether-Lumefantrine or Artesunate) | Chloroquine (3 days) |
| Liver-stage treatment | Not needed (no hypnozoites) | Primaquine 14 days — after G6PD testing |
| Hospitalisation | Required for severe Pf (any danger sign) | Usually outpatient unless severe anaemia |
| India distribution | Odisha, Jharkhand, Chhattisgarh, NE India | North India, Maharashtra, Gujarat, Rajasthan |
Malaria RDT vs Peripheral Blood Smear vs PCR
Three tests are used for malaria diagnosis in India — each with distinct advantages and appropriate clinical roles. Understanding when each is used helps patients navigate the diagnostic pathway and understand why their doctor may order one after another.
भारत में मलेरिया निदान के लिए तीन परीक्षण उपयोग किए जाते हैं — प्रत्येक के अलग फायदे और उचित नैदानिक भूमिकाएं हैं।Best for: rapid diagnosis at any healthcare level — PHC, sub-centre, dispensary, private clinic. No microscope, electricity, or skilled technician required. Result in 15–30 minutes. Detects Pf (HRP-2) and all-species (pLDH). Sensitivity: 95%+ for Pf above 100 parasites/µL; 75–90% for Pv. Limitations: cannot quantify parasitaemia (parasite density), cannot detect all species equally, HRP-2 persistence causes false positives post-treatment, HRP-2 gene deletion strains cause false negatives. NVBDCP policy: RDT is the primary test for all fever patients in endemic areas.
Thick and thin blood smears stained with Giemsa remain the gold standard — 95–98% sensitive and specific when performed by an experienced microscopist. Advantages over RDT: quantifies parasitaemia (parasite count per µL — critical for severe malaria assessment), identifies all four species including P. malariae and P. ovale (missed by standard RDT), detects gametocytes (for transmission assessment), and monitors treatment response (repeat smear at 24–48–72 hours confirms parasite clearance). Limitation: requires microscope, Giemsa stain, and trained microscopist — not always available at rural health facilities. NVBDCP requires confirmatory smear for all RDT-positive cases before treatment in PHCs.
Malaria PCR (nested PCR or real-time PCR) detects Plasmodium DNA from any species with near-100% sensitivity — including sub-microscopic parasitaemia (very low parasite counts that smear and RDT miss). Species identification is definitive. Used when: RDT and smear are discordant, species identification is uncertain (mixed infections), treatment failure investigation, diagnosis in returning travellers, and research/surveillance. Limitation: expensive (₹1,500–3,000), requires specialised laboratory, 24–48 hour turnaround — not available at PHC level. Ordered by NVBDCP reference laboratories and large private labs (Dr Lal, SRL, Metropolis).
Fever in endemic area / monsoon → RDT first. RDT positive → confirmatory blood smear + CBC + LFT + creatinine (for severity assessment). RDT negative but fever persists → repeat blood smear on two consecutive days + dengue NS1/antibody test (dengue mimics malaria in monsoon). Treatment failure or uncertain species → PCR. Returning traveller from malaria-endemic region → smear + PCR preferred over RDT alone (sub-microscopic parasitaemia common in partially immune travellers).
Malaria in India — Season, Geography & High-Risk Groups
India accounts for approximately 83% of all malaria cases in the South-East Asia region. Despite significant progress under the National Framework for Malaria Elimination (NFME) — with a target of malaria elimination by 2030 — transmission remains intense in tribal, forested, and peri-urban areas. Understanding India's malaria geography helps interpret your risk:
भारत दक्षिण-पूर्व एशिया क्षेत्र के सभी मलेरिया मामलों का लगभग 83% हिस्सा है। 2030 तक मलेरिया उन्मूलन के लक्ष्य के बावजूद, आदिवासी, वनीय, और शहरी क्षेत्रों में संचरण तीव्र है।Odisha contributes the highest number of Pf cases nationally — with a high proportion of HRP-2-deleted strains that cause false negative RDTs. Jharkhand, Chhattisgarh, Madhya Pradesh, and the North-East Indian states (Assam, Meghalaya, Tripura, Mizoram, Manipur, Arunachal Pradesh) have high Pf malaria with significant mortality risk. Tribal and forested populations in these states — particularly those working in forest collection, mining, or construction — are the highest-risk groups. Artemisinin partial resistance (ART-R) has been detected in some strains from the Greater Mekong Subregion and is being monitored in NE India.
Maharashtra, Gujarat, Rajasthan, Delhi NCR, Uttar Pradesh, Bihar, and West Bengal have predominantly Pv malaria. Urban malaria is a growing challenge — Anopheles stephensi (the urban malaria vector) has adapted to breed in urban water storage containers, overhead tanks, and construction sites in Indian cities. This "urban malaria" is seen year-round in cities (not just the monsoon) and is often misdiagnosed as dengue or viral fever. Pv relapses are a particular challenge — a patient treated and apparently cured may present months later with the same symptoms from hypnozoite reactivation.
India's malaria transmission peaks 4–6 weeks after the onset of the monsoon — typically July through November, with the peak in August–September in most states. The Anopheles mosquito (the malaria vector) breeds in clean, slow-moving or stagnant water — pools, rice paddies, irrigation channels, construction sites, and waterlogged urban areas. During peak malaria season, any fever above 38°C in a patient from or recently returning from an endemic area should have malaria testing within 24 hours — delays in Pf treatment directly increase mortality.
Both malaria and dengue peak in the monsoon, both cause high fever, thrombocytopenia (platelet drop), body aches, and headache — and both are transmitted by mosquitoes in India. Key clinical differences: malaria classically causes rigors (shaking chills) with cyclical fever (every 48 or 72 hours for Pv/Pm), while dengue causes more continuous fever with a characteristic rash. However, both can present atypically. It is common to test for both simultaneously in the monsoon season — the RDT for malaria and NS1 antigen/IgM antibody for dengue in the same blood draw. Platelet drop is severe in both and must be monitored daily by CBC.
What Happens After a Positive Malaria Antigen Test?
A positive malaria RDT initiates an immediate clinical response — the specific steps depending on the species identified and the severity of the patient's clinical state. Under India's NVBDCP programme, all positive malaria cases must be treated with government-approved first-line regimens, reported to the district health authority (for epidemiological tracking), and followed up to confirm parasite clearance.
पॉजिटिव मलेरिया RDT तत्काल नैदानिक प्रतिक्रिया शुरू करता है। NVBDCP के तहत सभी पॉजिटिव मलेरिया मामलों का उपचार, जिला स्वास्थ्य प्राधिकरण को सूचना, और परजीवी उन्मूलन की निगरानी अनिवार्य है।Uncomplicated P. vivax: Chloroquine (25 mg/kg over 3 days) for blood-stage treatment + Primaquine (0.25 mg/kg daily for 14 days) for liver-stage hypnozoites to prevent relapse. MANDATORY before primaquine: G6PD (Glucose-6-Phosphate Dehydrogenase) testing — G6PD deficiency is common in India (5–15% in endemic communities) and primaquine causes life-threatening haemolysis in G6PD-deficient patients. Low-dose primaquine (0.75 mg/kg weekly for 8 weeks) is an alternative for G6PD-deficient patients. Fever resolves within 24–48 hours of chloroquine. Monitor CBC — platelet count, haemoglobin. All Pv patients should complete the full 14-day primaquine course to prevent relapse.
Uncomplicated Pf: Artemisinin-based Combination Therapy (ACT) — Artemether-Lumefantrine (AL, 6-dose regimen over 3 days) or Artesunate-SP per NVBDCP current guidelines. Never use chloroquine for Pf (widespread chloroquine resistance). Assess for severity before outpatient treatment: WHO severe malaria criteria include altered consciousness, respiratory distress, severe anaemia (Hb below 5 g/dL), hypoglycaemia, renal failure, spontaneous bleeding, hyperparasitaemia (above 5% parasitised RBCs), shock. If any severe feature is present — immediate hospitalisation and IV Artesunate. G6PD testing not required for ACT. Blood smear at 48 and 72 hours confirms parasite clearance.
Day 3 after starting ACT (or chloroquine for Pv): repeat blood smear to confirm parasite clearance. Day 7 and Day 28: repeat smear/RDT to detect treatment failure or early recrudescence (Pf) or early relapse (Pv). CBC monitoring: platelet count typically drops in first 3–5 days of malaria then rises sharply after parasite clearance — a rising platelet count confirms treatment response. Haemoglobin may temporarily fall further before recovering. LFT and creatinine should be monitored in severe malaria and in elderly patients to detect drug toxicity and organ complications.
Go to hospital emergency immediately if malaria is positive AND any of these danger signs are present: confusion, drowsiness, or loss of consciousness (cerebral malaria); severe difficulty breathing; jaundice (yellowing — liver involvement); very dark or black urine (blackwater fever — haemoglobinuria); inability to stand or walk; seizures; severe vomiting preventing oral medication; platelet count below 20,000/µL with bleeding; haemoglobin below 5 g/dL; pregnancy with malaria (all malaria in pregnancy is high risk). Any child under 5 with positive malaria should be assessed by a paediatrician regardless of apparent severity.

The best malaria treatment is prevention. Anopheles mosquitoes — the malaria vector — bite primarily between dusk and dawn (unlike Aedes for dengue which bites during the day). Personal protection during evening and night hours, particularly during the monsoon season (July–November) in endemic areas, significantly reduces malaria risk. Effective personal protection includes: DEET-based or picaridin mosquito repellents on exposed skin, permethrin-treated bed nets (Long-Lasting Insecticidal Nets — LLINs, provided free under NVBDCP), and full-sleeve clothing from dusk onwards. No malaria vaccine is currently routinely available in India — prevention depends on mosquito control and personal protection.

P. falciparum (Pf) malaria is a serious infection that can progress rapidly to life-threatening severe malaria — and must be taken seriously. However, not all Pf malaria requires hospitalisation. Uncomplicated Pf malaria (alert, able to eat and drink, no danger signs) can be treated as an outpatient with oral ACT (Artemether-Lumefantrine) with close daily monitoring. You must be hospitalised immediately if any of these danger signs are present: confusion or altered mental state, inability to sit or stand, severe vomiting preventing oral medication, seizures, difficulty breathing, jaundice (yellow eyes/skin), very dark or black urine (haemoglobinuria), haemoglobin below 5 g/dL on CBC, platelet count below 20,000/µL with any bleeding, or parasitaemia above 5% on blood smear. Any child under 5 or pregnant woman with Pf should be hospitalised regardless of apparent severity. Even in outpatient Pf treatment, a repeat blood smear at 48 and 72 hours is mandatory to confirm parasite clearance.
उत्तर: Pf मलेरिया गंभीर है लेकिन हर मामले में भर्ती की जरूरत नहीं। सरल Pf = मौखिक ACT + दैनिक निगरानी। भर्ती तब: भ्रम, गंभीर उल्टी, दौरे, सांस लेने में कठिनाई, पीलिया, काला पेशाब, Hb <5 g/dL, या platelets <20,000/µL। 5 साल से कम बच्चे और गर्भवती = हमेशा भर्ती।A negative malaria RDT does not rule out malaria — the false negative rate can be 5–25% depending on the clinical situation. The most common reasons for false negative results in India are: very early infection before sufficient antigens have accumulated (test too early in illness — repeat in 24 hours); HRP-2 gene deletion strains of P. falciparum (increasingly common in Odisha, Jharkhand, Chhattisgarh) that cause false negative HRP-2 lines; very low parasitaemia in partially immune individuals; and P. malariae or P. ovale infections (standard RDTs are less sensitive for these). Action with fever + negative RDT: request a thick and thin peripheral blood smear — if the smear is also negative but fever persists and malaria exposure is plausible, repeat both tests every 12–24 hours for 3 days. Simultaneously test for dengue (NS1 antigen) and typhoid (Widal or blood culture), as these conditions strongly mimic malaria in the Indian monsoon season. Never dismiss malaria diagnosis based solely on a single negative RDT in a patient with fever, rigors, and epidemiological risk.
उत्तर: नेगेटिव RDT मलेरिया को नकारता नहीं। अगले कदम: पेरिफेरल ब्लड स्मियर, 24 घंटे बाद दोहराएं, डेंगू NS1 और Widal भी जांचें। HRP-2 deletion strains (ओडिशा, झारखंड) में RDT झूठा नेगेटिव देता है।P. vivax malaria treatment includes primaquine — an 8-aminoquinoline drug that kills the dormant liver-stage parasites (hypnozoites) to prevent relapse. Primaquine causes oxidative haemolysis (destruction of red blood cells) in patients with G6PD (Glucose-6-Phosphate Dehydrogenase) deficiency — an inherited enzyme deficiency that is common in India, particularly in tribal populations from malaria-endemic regions (estimated 5–15% prevalence in high-endemic communities). In G6PD-deficient patients, standard primaquine doses can cause severe life-threatening haemolytic anaemia — rapidly dropping haemoglobin, dark red/brown urine (haemoglobinuria), and acute kidney injury. G6PD testing is therefore mandatory before prescribing primaquine for any Pv patient. G6PD-deficient patients can still receive low-dose weekly primaquine (0.75 mg/kg once weekly for 8 weeks) under supervised conditions — but standard daily 14-day primaquine is contraindicated. Your government PHC and malaria control programme are required to provide G6PD testing free of charge.
उत्तर: Pv उपचार में primaquine (हाइपनोज़ोइट्स को मारने के लिए) G6PD की कमी वाले रोगियों में जीवन-धमकी देने वाली हेमोलिटिक एनीमिया पैदा करता है। G6PD की कमी भारत में 5–15% स्थानिक समुदायों में है। Primaquine से पहले G6PD परीक्षण अनिवार्य है।This is a very important clinical question — distinguishing relapse from reinfection in Pv malaria. P. vivax can cause relapse from hypnozoites (dormant liver-stage parasites) weeks to years after the initial infection — and in India, early relapses (within 3 months) and late relapses (3–12 months) are both common. A key question is whether you completed the full 14-day primaquine course after your first infection: if you did not receive primaquine, or did not complete the full 14-day course (poor adherence is common because patients feel well once chloroquine clears the blood stage), your relapse risk is very high. The treatment for relapse is the same as primary infection (chloroquine + primaquine 14 days), but a G6PD test must be repeated if not recently done. If relapses occur despite completing proper primaquine treatment — this suggests primaquine treatment failure, which is increasingly recognised in India, and your doctor may use a longer primaquine course (double dose under supervision for chloroquine-tolerant relapsing Pv).
उत्तर: Pv हाइपनोज़ोइट्स से 6 महीने बाद पुनरावृत्ति हो सकती है। यदि आपने Primaquine का पूरा 14-दिन कोर्स पूरा नहीं किया, तो पुनरावृत्ति जोखिम अधिक है। उपचार: chloroquine + primaquine 14 दिन (G6PD पुनः परीक्षण के बाद)।No — fasting is absolutely not required for the malaria antigen test. The test detects malaria parasite proteins (HRP-2 and pLDH) in blood — these are not affected by food intake, time of day, or any dietary factors. The test can and should be done at any time when fever is present — in fact, testing during or just after a fever spike (when parasite density in blood is highest) may improve sensitivity. For the associated CBC (complete blood count) typically ordered alongside malaria testing, fasting is also not required. If the malaria test is part of a broader fever panel that includes fasting blood sugar or lipid profile, follow those specific fasting instructions for those tests, but the malaria RDT requires no preparation of any kind.
उत्तर: नहीं — मलेरिया एंटीजन टेस्ट के लिए उपवास बिल्कुल आवश्यक नहीं है। परजीवी प्रोटीन भोजन सेवन से प्रभावित नहीं होते। बुखार के दौरान या तुरंत बाद परीक्षण करना सबसे अच्छा है।Malaria and dengue are the two most common vector-borne fevers in India's monsoon season and frequently mimic each other — which is why both tests are often ordered together. Key differences to help clinically distinguish them: Malaria classically causes rigors (shaking chills) with cyclical fever patterns — Pv causes fever every 48 hours (tertian), Pm causes fever every 72 hours (quartan); however, early malaria often does not show the classic pattern. Dengue typically causes a sudden-onset continuous fever with severe bodyache (breakbone fever), retro-orbital pain (pain behind the eyes), and a characteristic petechial or maculopapular rash (appearing on day 3–5). On CBC: both cause thrombocytopenia — but dengue typically causes a more dramatic platelet drop (sometimes below 10,000–20,000/µL) and a characteristic haematocrit rise (haemoconcentration from plasma leakage) that is not seen in malaria. Dengue does not respond to antimalarials and malaria does not respond to dengue supportive care — misdiagnosis delays correct treatment. Testing for both simultaneously using combined fever panels is the practical approach in the Indian monsoon season.
उत्तर: मलेरिया = ठंड के साथ चक्रीय बुखार (48 या 72 घंटे), कोई रैश नहीं। डेंगू = अचानक तेज़ बुखार, आंखों के पीछे दर्द, रैश, हेमेटोक्रिट वृद्धि। दोनों प्लेटलेट गिरावट का कारण बनते हैं। मानसून में दोनों एक साथ जांचें।- WHO — Malaria Diagnosis: WHO Malaria RDT Product Testing Guidelines
