The study was planned in Department of Pathology in Darbhanga Medical College and Hospital, Darbhanga, Bihar from Jan 2017 to July 2017. Patients found positive for the malaria were undergone the Rapid Diagnosed Tests (RDT) and Peripheral smears tests. The detection of malarial antigens by variety of Rapid diagnostic test available is of great value especially in severe and complicated malaria wherein blood smears may be negative. Hence, this study was planned to compare the gold standard i.e. peripheral blood smear examination and the newer rapid diagnostic test (malaria plasmodium falciparum/ plasmodium vivax antigen card) to know the diagnostic accuracy of rapid diagnostic kits. The data generated from the present study concludes that peripheral smears are considered to be gold standard for diagnosis of malaria. RDTs can be more sensitive and specific than peripheral smears. Peripheral smears is time consuming as one test requires 60minutes, in comparison to that RDT is simple more objective, requires no equipment, but only drawback is it is quite expensive. RDT does not have any subject bias whereas in microscopy the results are affected by the skill and workload of the microscopists.
