Bartonella quintana Antibodies, IgG & IgM by IFA
Also known as: BART PAN
Use
This test may assist in confirming suspected Trench fever in patients with typical signs, symptoms, and a compatible exposure history. Detection of antibodies suggests either a current or past infection with Bartonella quintana, aiding in the diagnosis and management of the disease.
Special Instructions
Parallel testing is preferred, and convalescent specimens must be received within 30 days from receipt of the acute specimens. Mark specimens plainly as 'acute' or 'convalescent.' Refrigerate specimens during storage and transport.
Limitations
This test has not been cleared or approved by the US Food and Drug Administration. A low positive result may suggest past exposure or infection, while a high positive result may indicate recent or current infection but is inconclusive for diagnosis. Seroconversion between acute and convalescent sera is considered strong evidence of recent infection. The best evidence for infection is a significant change on two appropriately timed specimens where both tests are performed in the same laboratory at the same time. Low levels of IgM antibodies may occasionally persist for more than 12 months post-infection.
