About this test
Available on request, but worth being clear about: TB antibody serology performs poorly compared with culture, GeneXpert and the interferon-gamma tests, and international guidance advises against relying on it. We list it because it is asked for; we would normally recommend one of the alternatives.
What it measures
- Anti-tuberculous IgG
- Anti-tuberculous IgM
A note on results. A single test is one part of a clinical picture, not a diagnosis. Discuss your report with a qualified doctor, who will read it alongside your history and examination.
