Babesia species, Molecular Detection, PCR, Blood
Use
This test is crucial for initial screening or confirmatory testing for suspected babesiosis during the acute febrile stage of infection, particularly in patients from endemic areas. It is especially useful when Giemsa-stained peripheral blood smears do not reveal any organisms, or when the morphology of organisms is inconclusive. The test identifies the DNA of Babesia species, providing a more sensitive alternative to microscopic examination of blood smears.
Special Instructions
This assay is a qualitative test reporting results as either negative or positive for Babesia species DNA. If not ordering electronically, clients should complete, print, and send a Microbiology Test Request (T244) with the specimen. Proper specimen handling is crucial, as inadequate collection or improper storage may invalidate results.
Limitations
The test is designed to detect symptomatic infections with Babesia microti, Babesia duncani, and Babesia divergens/MO-1. However, it may also detect asymptomatic parasitemia in endemic areas, thus it should be used in patients with symptoms and a clinical history consistent with babesiosis. Inhibitory substances may cause false-negative results, and the test does not cross-react with malaria parasites. It's essential to correlate positive results with blood smear microscopy, serological results, and clinical findings.
