Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestThe QuantiFERON-TB Gold test is a blood-based method for detecting infection with Mycobacterium tuberculosis, the bacterium that causes tuberculosis. Unlike traditional skin testing, it measures the immune response in a blood sample and requires only a single visit for collection.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Reading
QuantiFERON-TB Gold is an interferon-gamma release assay, commonly abbreviated as IGRA. It identifies whether a person's immune cells have been sensitized to tuberculosis bacteria by measuring the interferon-gamma they release when exposed to specific TB antigens in the laboratory.
The test uses a small sample of blood collected into specialized tubes. One tube contains antigens derived from M. tuberculosis, another serves as a negative control, and a third acts as a positive control to confirm that the immune cells in the sample are functioning properly. After incubation, the amount of interferon-gamma produced is measured and compared across the tubes.
Because the antigens used are absent from the BCG vaccine and from most non-tuberculous mycobacteria, the test is less likely to produce a false positive result in people who have received BCG vaccination. It also avoids the need for a follow-up visit to read a skin reaction, since the result comes from a laboratory analysis of the blood sample.
A positive result indicates that the immune system has been exposed to tuberculosis bacteria at some point. It does not by itself distinguish between latent tuberculosis infection, in which the bacteria are present but inactive, and active tuberculosis disease. Additional evaluation by a healthcare provider is needed to interpret the result in the context of symptoms, history, and other findings.
