Detailed explanation-1: -Malaria Diagnostic Tests. Microscopic examination remains the “gold standard” for laboratory confirmation of malaria. These tests should be performed immediately when ordered by a health-care provider.
Detailed explanation-2: -Artemisinin-based combination therapies (ACTs) are the recommended treatments for uncomplicated falciparum malaria. The following ACTs are recommended: – Artemether + lumefantrine; artesunate + amodiaquine; artesunate + mefloquine; artesunate + sulfadoxine-pyrimethamine, and dihydroartemisinin + piperaquine .
Detailed explanation-3: -Microscopy is still considered the “gold standard” for malaria diagnosis in endemic countries. This method has a sensitivity of 50–500 parasites/l [6], is inexpensive, and allows the identification of species and parasite density [7, 8].
Detailed explanation-4: -Giemsa is the recommended stain for malaria microscopy, and diagnosis requires examination of both thin and thick films from the same patient. Light microscopy is the diagnostic standard against which other diagnostic methods have traditionally been compared.
