Diagnostic Use Or Instructions

Rapid diagnostic test (RDT,Pf/Pv)

The test detects circulating P.falciparum (P.f) antigen and a Pan-malarial antigen that is common to all four species of malaria. The test cannot separate P.f mixed infestations. Occasionally, residual antigen may be detected for several days following the elimination of the parasite by anti-malarial treatment. Diagnosis should be made using the results of this test together with the other laboratory and clinical findings.
