Limitations
A single negative result does not completely rule out parasitic infestation. For suspected protozoal, filarial, or trypanosomal infections, testing should be repeated at least three times with samples collected at different points in the fever cycle. Specific identification depends on the characteristics of the Plasmodium species affecting the infection.
