Ordering Recommendation

First-line test for diagnosing acute babesiosis. 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). If also investigating Anaplasmosis or Ehrlichiosis, consider Tick-Borne Disease Panel by PCR, Blood (2008670).
