One of the biggest hazards to world health is still malaria, especially in tropical and subtropical areas where quick laboratory testing is difficult to obtain. In a world where every minute counts, early and accurate malaria diagnosis is essential to reduce mortality, guide treatment, and prevent outbreaks.
Among the most dangerous malaria-causing parasites is Plasmodium falciparum (P. Falciparum), responsible for the majority of severe cases and deaths worldwide. With the Malaria P.f. pLDH/HRP2 Rapid Test Kit, clinicians and health workers gain a vital tool to identify infections quickly and reliably, even in remote or resource-limited settings.
What Is Plasmodium falciparum and Why Is It Dangerous?
Malaria is a parasitic infection transmitted by the bite of infected female Anopheles mosquitoes. Among the five Plasmodium species that infect humans, P. Falciparum is the most lethal. It accounts for more than 50% of global malaria cases and nearly all malaria-related deaths, particularly in Sub-Saharan Africa and parts of Asia and Latin America.
Life Cycle and Symptoms
After entering the bloodstream, the parasites travel to the liver, where they mature and multiply. Within a week or two, they re-enter the bloodstream, infecting red blood cells and rapidly causing symptoms such as:
– High fever and chills
– Severe headache
– Vomiting and diarrhea
– Muscle pain
– Anemia and fatigue
– In extreme cases: coma, organ failure, or death
Without treatment, P. Falciparum can progress quickly to severe malaria, characterized by impaired consciousness, respiratory distress, metabolic acidosis, and multi-organ failure.
The Need for Rapid and Reliable Malaria Diagnosis
Timely diagnosis is the cornerstone of effective malaria management. Although accurate, traditional diagnosis techniques like microscopy necessitate trained personnel and laboratory facilities, which are not always available in endemic or rural areas.
In contrast, Rapid Diagnostic Tests (RDTs) offer a cost-effective, accessible, and fast alternative, allowing frontline workers to confirm malaria within minutes and begin treatment immediately.
Why Test for Both pLDH and HRP2 Antigens?
The Malaria P.f. pLDH/HRP2 Rapid Test Kit detects two key biomarkers:
– HRP2 (Histidine-Rich Protein 2): A protein secreted by P. Falciparum, commonly used in RDTs. However, HRP2 may persist in the bloodstream for days after treatment, leading to false positives.
– pLDH (Plasmodium lactate dehydrogenase): An enzyme released by live parasites, providing a more current snapshot of infection status.
This test’s combination of the two markers improves diagnostic accuracy by identifying recent parasite presence and active infections, supporting well-informed treatment choices and patient monitoring.
Introducing the Malaria P.f. pLDH/HRP2 Rapid Test Kit by Vitrosens
Designed for professional use, the Malaria P.f. pLDH/HRP2 Rapid Test Kit is a lateral flow immunochromatographic assay that detects P. Falciparum antigens in capillary or venous whole blood samples. The test is suitable for use in hospitals, clinics, mobile labs, and fieldwork environments where laboratory access is limited.
Top Benefits at a Glance
✔ Dual Antigen Detection: Targets both HRP2 and pLDH for enhanced sensitivity and specificity.
✔ Fast Results: Delivers clear, accurate results in just 15 minutes.
✔ Simple Procedure: Requires no specialized equipment or electricity.
✔ Field-Friendly Format: Individually sealed cassettes with built-in control lines.
✔ Reliable: Validated to detect as low as 20 IU/mL of pLDH/HRP2 antigens.
✔ No Cross-Reactivity: Does not cross-react with other bloodborne pathogens like HIV, dengue, or hepatitis.
How to Use the Malaria P.f. pLDH/HRP2 Rapid Test Kit
Step-by-step instructions for health professionals:
Before Testing
- Bring the kit and samples to room temperature (18–30°C) if stored in refrigeration.
- Ensure the cassette is undamaged and within its expiry date.
- Put on gloves and label the test cassette with patient information.
Sample Collection
Fingerstick Whole Blood
– Clean the finger and puncture using a sterile lancet.
– Wipe away the first drop of blood, collect 5 μL with the dropper.
Venipuncture Whole Blood
– Use freshly collected blood within 24 hours.
– Transfer 5 μL to the test cassette using the provided dropper.
Testing Procedure
- Add the blood sample to the sample well (S) on the test cassette.
- Add 3 drops of sample diluent into the diluent well (D).
- Wait 15 minutes.
- Interpret the result visually using the control and test lines.
How to Read the Results
– Positive for HRP2 and pLDH: All three lines visible (C, HRP2, pLDH) – indicates active P. Falciparum infection.
– Positive for HRP2 only: C and HRP2 lines visible – suggests presence of parasite antigens.
– Positive for pLDH only: C and pLDH lines visible – suggests active parasitemia.
– Negative: Only the control line (C) is visible.
– Invalid: No control line appears – retest with a new device.
Why Choose This Product?
