Test Code BARRP Bartonella, Molecular Detection, PCR

Reporting Name

Bartonella PCR

Useful For

Diagnosing Bartonella infection

Performing Laboratory

Mayo Medical Laboratories in Rochester

Specimen Type


Specimen Required

The high sensitivity of amplification by PCR requires the specimen to be processed in an environment in which contamination of the specimen by Bartonella species DNA is unlikely.


Submit only 1 of the following specimens:


Specimen Type: Fresh tissue or biopsy

Sources: Heart valve, liver, lymph node, or spleen

Container/Tube: Sterile container

Specimen Volume: Entire collection or 5 mm(3)

Collection Instructions: Collect fresh tissue specimen.

Specimen Stability Information: Refrigerated (preferred) <7 days/ Frozen <7 days  


Specimen Type: Paraffin-embedded tissue block

Sources: Heart valve, liver, lymph node, or spleen

Container/Tube: Sterile vial

Specimen Volume:  Submit formalin-fixed paraffin-embedded tissue block to be cut and returned; or two to five 10-micron sections in a sterile container.

Specimen Stability Information: Ambient (preferred)/Refrigerated


Specimen Type: Fluid

Sources: Cerebrospinal, synovial, or ocular (eg, vitreous humor fluid)

Container/Tube: Sterile vial

Specimen Volume: 0.5 mL

Specimen Stability Information: Refrigerated (preferred) <7 days/Frozen <7 days

Advisory Information:

BART / Bartonella Antibody Panel, IgG and IgM, Serum and Warthin-Starry tissue stain (70012 / Pathology Consultation) should be considered if PCR is negative and there is a strong suspicion of disease caused by these organisms.

Necessary Information:

Specimen source is required.
