Bartonella quintana Antibody, IgG by IFA
Also known as: QUINT G
Use
The Bartonella quintana Antibody, IgG by IFA test is designed to assist in confirming suspected Trench fever in patients who exhibit typical signs and symptoms consistent with the disease, as well as a compatible exposure history. A low positive result suggests past exposure or infection, while a high positive result may indicate an active or recent infection. However, the test is not conclusive for diagnosis based solely on a positive result, hence seroconversion between acute and convalescent sera, which is considered strong evidence of recent infection, should be evaluated. The test helps in the assessment of the presence of Bartonella quintana IgG antibodies to suggest current or past infection.

Limitations
Despite positive results, the test may not conclusively diagnose Bartonella quintana infection. Seroconversion between acute and convalescent sera is a stronger indicator of recent infection. Variability in antibody levels due to previous exposures may obscure interpretation. The test results should be considered alongside other serological and clinical evaluations. Environmental factors such as contamination or hemolysis can potentially affect results. Additionally, repeat IFA testing within a 10-14 day window may aid interpretation for equivocal findings.
