Parasites Smear (Giemsa Stain), Blood
Also known as: GIEMSA
Use
This test is used to screen for and detect blood parasites including microfilaria, Babesia, Trypanosoma, and Plasmodium species. It is critical for the diagnosis and management of parasitic infections, such as malaria and Chagas disease. Patient travel history is necessary to assist in interpreting the results as certain parasites are endemic to specific regions.
Special Instructions

Limitations
The examination of smears from multiple specimens might be necessary due to the intermittent nature of parasitemia. For accurate diagnosis of malaria, it's recommended to examine three specimens taken at six to eight-hour intervals on three successive days, irrespective of clinical symptoms.
