Interpretive Data

Acute, symptomatic malaria: This qualitative test is intended only for the species identification of microscopically confirmed malaria infections. It is not intended to monitor treatment response or parasite clearance.

A positive result may be obtained in the absence of visible parasites. In coinfections with two or more Plasmodium species, differences in parasite burden may lead to failure of one or more species to be identified.

Asymptomatic/subclinical malaria: PCR is recommended by the CDC as the most sensitive laboratory test for detection of asymptomatic or subclinical malaria in refugee screening programs. PCR is only recommended for routine screening of refugees from sub-Saharan Africa who have not received predeparture therapy.

A negative result on this assay does not rule out the presence of PCR inhibitors in the patient specimen or assay-specific nucleic acid in concentrations below the level of detection by the assay.
