Rapid diagnostic tests (RDTs) are diagnostic assays designed for use at the point-of-care (POC), and can be adapted for use in low-resource settings. An RDT is low-cost, simple to operate and read, sensitive, specific, stable at high temperatures, and works in a short period of time.
What is the principle of malaria parasite test?
The principles of tests stem from detection of malaria parasites’ protein i.e. histidine. Where antibody method is used, it means detection of the presence of antibodies against histidine in the human serum and where whole blood is used, it implies detection of malaria parasites’ histidine on the red blood cells[6].
