Babesia Species by PCR
Ordering Recommendation

First-line test for diagnosing acute babesiosis. This PCR test detects nucleic acid from B. microti and detects but does not differentiate between B. duncaniB. divergens, strain MO-1, and strain EU-1. Blood smears are also appropriate for diagnosing and monitoring babesiosis disease; refer to Parasites Smear (Giemsa Stain), Blood (0049025).
