Babesia Species by PCR
First-line test for diagnosing acute babesiosis. Detects nucleic acid from B. microti and detects but does not differentiate between B. duncani, B. 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).
Qualitative Polymerase Chain Reaction
New York DOH Approval Status
Lavender (EDTA) or Pink (K2EDTA).
Transport 1 mL whole blood. (Min: 0.6 mL)
Serum, plasma, and heparinized specimens.
Ambient: 24 hours; Refrigerated: 1 week; Frozen: 1 month
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.
This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
Laboratory Developed Test (LDT)
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.
