HelpTest Code BARTB Bartonella, Molecular Detection, PCR, Blood
Additional Codes
CNE Order Code: BartonellaPCR
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.

Preferred: Lavender top (EDTA)
Acceptable: Royal blue top (EDTA), pink top (EDTA), or sterile vial containing EDTA-derived aliquot
Specimen Volume: 1 mL

Interpretation
A positive result indicates the presence of Bartonella species DNA.
A negative result indicates the absence of detectable Bartonella DNA but does not negate the presence of the organism and may occur due to inhibition of PCR, sequence variability underlying primers or probes, or the presence of Bartonella DNA in quantities less than the limit of detection of the assay.
