Bartonella quintana Antibody, IgM by IFA
Also known as: QUINT M
Use
The Bartonella quintana Antibody, IgM by IFA test is intended to assist in confirming suspected Trench fever, particularly in patients presenting with typical symptoms and a compatible exposure history. Detection of IgM antibodies indicates a recent infection with Bartonella quintana. However, low levels of IgM antibodies may occasionally persist for more than 12 months post-infection.
Special Instructions
Parallel testing is preferred, and convalescent specimens must be received within 30 days from the receipt of the acute specimens. Mark specimens plainly as acute or convalescent for accurate results.
Limitations
This test was developed and its performance characteristics determined by ARUP Laboratories; it is not FDA cleared or approved and is intended for clinical purposes. The sensitivity and specificity are not detailed, and the persistence of IgM antibodies beyond the acute infection phase may impact interpretation, as low levels may linger beyond 12 months post-infection.
