HelpTest Code BARTB Bartonella, Molecular Detection, PCR, Blood
Reporting Name
Bartonella PCR, BUseful For
Aiding in the diagnosis of Bartonella infection when Bartonella DNA would be expected to be present in blood, especially endocarditis
Performing Laboratory
Mayo Clinic Laboratories in Rochester
Specimen Type
Whole Blood EDTAOrdering Guidance
If this test result is negative and there is a strong suspicion of disease caused by these organisms, consider BART / Bartonella Antibody Panel, IgG and IgM, Serum and Warthin-Starry tissue stain (PATHC / Pathology Consultation) testing.
Specimen Required
The high sensitivity of amplification by polymerase chain reaction requires the specimen to be processed in an environment in which contamination of the specimen by Bartonella species DNA is unlikely.

Cautions
This test does not differentiate between Bartonella henselae and Bartonella quintana.
Test results should be used as an aid in diagnosis. The single assay should not be used as the only criteria to form a clinical conclusion, but results should be correlated with patient symptoms and clinical presentation. A negative result does not negate the presence of the organism or active disease.
