| NBS code | LBC11781 |
| Service code | 37112 |
Reporting Name
Bartonella PCR, BSpecimen 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.
