Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestThe QuantiFERON TB Gold blood test is a laboratory method for detecting infection with Mycobacterium tuberculosis, the bacterium that causes tuberculosis. Unlike skin testing, this assay uses a blood sample to measure the immune system's response to specific TB antigens.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Brea
QuantiFERON TB Gold is an interferon-gamma release assay, often abbreviated as IGRA. It was developed as an alternative to the tuberculin skin test for identifying TB infection.
The test works by mixing a blood sample with synthetic peptides that correspond to proteins found in Mycobacterium tuberculosis. If the person has been infected, their T cells recognize these peptides and release interferon-gamma, which the laboratory measures.
A key advantage of the QuantiFERON approach is that it does not cross-react with the BCG vaccine, a common cause of false-positive skin test results. It also requires only a single blood draw and a follow-up laboratory visit is not needed to read a skin reaction.
Results are typically reported as positive, negative, or indeterminate. An indeterminate result means the test could not provide a clear answer, often because the immune response in the sample was too low or too high, and repeat testing may be considered.
