Babesia Species by PCR
Ordering Recommendation
First-line test to diagnose acute babesiosis. Detects nucleic acid from Babesia microti, and detects but does not differentiate between B. duncani, B. divergens, and Babesia strains MO-1 and EU-1. Blood smears are also appropriate to diagnose and monitor babesiosis; refer to Parasites Smear (Giemsa Stain), Blood (0049025). If also investigating anaplasmosis or ehrlichiosis, consider Tick-Borne Disease Panel by PCR, Blood (2008670).

Interpretive Data
A negative result does not rule out the presence of PCR inhibitors in the patient specimen or test-specific nucleic acid in concentrations below the level of detection by this test.
Laboratory Developed Test (LDT)
Note
This test detects and speciates B. microti. The nucleic acid from B. duncani, B. divergens, strain MO-1, and strain EU-1 will be detected by this test but cannot be differentiated.
