​The Malarial Ag Test is an RDT card test and is performed as part of the Malarial Parasite Screen, which includes the FBC and microscopic examination of thick and thin blood films to identify species. The card test can assist in the differential diagnosis between P. falciparum and the other Pan specific species (P.vivax, P.ovale, P.malariae). The RDT card test result is not reported independently but forms part of the Malaria testing and helps form the overall Malaria result reported.

NB at present it cannot be confirmed that the card test can detect the presence of Plasmodium Knowlesi, however the gold standard for Malaria detection is thick and thin blood film review in which P. Knowlesi will be identified.
