Rapid Malaria/Babesia Smear, Varies

Clinical Use

Use

This test is used for the rapid and accurate detection and species identification of Plasmodium and to detect Babesia, trypanosomes, and some species of microfilariae. It is an essential tool for confirming a presumptive diagnosis of malaria, determining the infecting Plasmodium species, and calculating the percentage of parasitemia, which can help predict prognosis and monitor treatment response. The test is also applicable for the detection of Trypanosoma and filariae species.

Special Instructions

This test should not be used as a primary screening test for malaria outside the Rochester, Minnesota area unless the specimen can be delivered within several hours after collection. Laboratories unable to deliver within that time should conduct initial screening in-house. Both blood and slides are required. Blood films are prepared using specialized instructions. Proper handling and timely delivery are essential for accurate results.

Limitations

Microscopy of Giemsa-stained blood films may not achieve optimal sensitivity; thick smears must be examined for best results. The degree of parasitemia can rapidly change, so calculations are most accurate immediately post-draw. Specimen aging or improper transport may degrade malaria parasites, making accurate parasitemia calculations difficult or impossible.
