Principle

Advantage Malaria PAN+Pf Card is an immunoassay based on the “Sandwich” principle. The conjugate contains colloidal gold conjugated to Pf specific monoclonal anti- HRP-2 antibody and monoclonal anti-pan specific pLDH antibody. The test uses monoclonal anti-Pf HRP-2 antibody (test line F) & monoclonal anti-pan specific pLDH antibody (test line P) immobilized on a nitrocellulose strip. The test sample is added to the device. On addition of assay buffer, the red blood cells get lysed. If the sample contains P.falciparum or P.vivax/P.malariae/P.ovale, the colloidal gold conjugate complexes the Pf specific HRP-2/ Pan specific pLDH in the lysed sample. This complex migrates through the nitrocellulose strip by capillary action. When the complex meets the line of the corresponding immobilized antibody, the complex is trapped forming a purplish pink band which confirms a reactive test result. Absence of a coloured band in the test region indicates a negative test result. To serve as a procedural control an additional line of anti-mouse antibody has been immobilized on the strip as control.

Evaluations

(i) WHO Evaluation:

The Advantage Malaria PAN+Pf Card test kit has been evaluated by WHO, Geneva using a panel of wild & cultured malaria positive sample and the results obtained are as follows:

(ii) In-house Evaluation
Analytical Sensitivity: The test can detect parasitemia levels of >50 parasites per µl of blood for P. falciparum (HRP-2), > 100 parasites per µl of blood for P. falciparum (pLDH) & P. vivax . The Advantage Malaria PAN+Pf Card has been evaluated in-house with malaria positive and negative clinical whole blood samples and compared with microscopic examination. The evaluation also included cross-reacting samples; Dengue, Rheumatoid factor, Leptospira, HIV, HCV, HBV, M. tuberculosis, Syphilis, Brucella, Scrub typhus positive samples. The results obtained are as follows:

Precision : Within-run and between-run precisions have been determined by testing 10 replicates of six specimens : two negative, two weak positive and two moderate positive. The C.V (%) of negative, weak positive and moderate positive samples were within 10% of the time.
