Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestThe TB Gold Blood Test, also known as the QuantiFERON Tuberculosis Lab Test, is an interferon-gamma release assay used to detect infection with Mycobacterium tuberculosis. Unlike skin testing, this blood-based method requires a single sample and avoids the need for a follow-up visit to read a reaction.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Pasadena
The QuantiFERON TB Gold test measures the immune system's response to specific tuberculosis antigens directly from a blood sample.
Tuberculosis is caused by Mycobacterium tuberculosis, a bacterium transmitted through the air when a person with active respiratory disease coughs or sneezes. Infection can remain latent, meaning the organism is present without causing symptoms and without being contagious, or it can progress to active disease that typically affects the lungs.
The QuantiFERON assay works by mixing a blood sample with synthetic peptides that represent proteins found in M. tuberculosis. If the person's T cells have been previously sensitized to these proteins, they release interferon-gamma, which the test quantifies. A result is considered positive when the interferon-gamma response exceeds the assay's established threshold.
Because the antigens used in this test are absent from the BCG vaccine and from most non-tuberculous mycobacteria, the QuantiFERON TB Gold test offers greater specificity than traditional tuberculin skin testing. It is commonly used in screening programs and in evaluating individuals with known or suspected exposure. Results should always be interpreted by a qualified healthcare professional alongside clinical history and other findings.
