Malaria Smear/ Blood smear for malarial parasites/ malarial parasites |
| Indication |
Diagnose malaria, parasitic infestation of blood; evaluate febrile disease of unknown origin. |
| Physiology |
Proper therapy depends upon identification of the specific variety of malaria parasite. Release of trophozoites and RBC debris result in a febrile response. Periodicity of fever correlates with type of malaria. Parasites are most likely to be detected just before onset of fever which is predictable in many cases. Multiple sampling at different times in the fever cycle may prove successful results. |
