Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestThe TB Gold blood test, also known as the QuantiFERON tuberculosis lab test, is a blood-based method for detecting infection with Mycobacterium tuberculosis, the bacterium that causes tuberculosis. It offers a laboratory alternative to traditional skin testing and is used to identify whether a person has been exposed to the TB organism.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Mesa
QuantiFERON TB Gold is an interferon-gamma release assay, or IGRA, that measures the immune system's response to specific TB antigens.
The test works by mixing a blood sample with synthetic peptides that mimic proteins found in Mycobacterium tuberculosis. If the person's immune cells have prior exposure to TB, they release interferon-gamma, which the assay detects and quantifies. This approach avoids many of the variables that can complicate tuberculin skin testing, such as prior BCG vaccination or reader interpretation.
QuantiFERON TB Gold is typically ordered when a person has signs or symptoms suggestive of TB, when there is known contact with an infectious case, or as part of screening for certain healthcare, employment, or immigration requirements. It cannot distinguish between latent TB infection and active TB disease on its own, so clinical evaluation and additional testing are needed when disease is suspected.
Results are generally reported as positive, negative, or indeterminate. A positive result indicates likely infection with TB bacteria, while a negative result makes infection less likely but does not rule it out entirely, especially in people with weakened immune systems. Indeterminate results may occur if the sample's immune response is insufficient, and repeat testing may be advised. Turnaround time is typically one to three business days after the specimen reaches the laboratory, and preparation follows the lab's instructions.
