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. Unlike traditional skin tests, this assay measures the immune system's response to specific TB proteins in a laboratory setting, offering a clear and reproducible result.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Wheeling
Tuberculosis remains a significant global health concern, and accurate detection is essential for both individual care and public health. The QuantiFERON TB Gold test provides a modern approach to identifying TB infection without the need for a skin prick or a follow-up visit to have a reaction read.
The test works by mixing a blood sample with synthetic peptides that mimic proteins found in M. tuberculosis. If the person's immune cells have been previously exposed to TB, they will release interferon-gamma in response. The laboratory then measures the amount of interferon-gamma produced, which indicates whether an infection is likely present.
The QuantiFERON TB Gold test is particularly useful because it can distinguish between true TB infection and prior BCG vaccination, which often causes false-positive results on the traditional tuberculin skin test. It also requires only a single blood draw, eliminating the need for a return visit to have a skin reaction assessed.
This test is typically ordered when a person has symptoms suggestive of TB, such as a persistent cough, fever, night sweats, or weight loss, or when there has been known exposure to someone with active TB. It may also be used for screening in certain occupational or healthcare settings. Results are generally available within one to three business days.
