ADVANTAGE P.f MALARIA CARD is an immunoassay based on the "Sandwich principle" . Colloidal gold is conjugated to monoclonal anti- Pf specific HRP-2 antibody. The test uses monoclonal anti-Pf HRP-2 antibody (test line F) 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 the colloidal gold conjugate complexes the Pf specific HRP-2 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.
