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 the traditional tuberculin skin test, this assay relies on a single blood draw and measures the immune system's response to specific TB antigens in a laboratory setting.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Orange
The QuantiFERON TB Gold assay is a blood-based method for identifying prior or current infection with the bacteria that cause tuberculosis.
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 been previously sensitized to TB, they release interferon-gamma, which the assay detects and quantifies.
Because the assay uses antigens that are absent from most non-tuberculous mycobacteria and from the BCG vaccine, it tends to produce fewer false-positive results than the tuberculin skin test in people who have received BCG. It also requires only one visit for sample collection, since there is no need to return for a skin reading.
Results are typically categorized as positive, negative, or indeterminate. A positive result suggests infection with TB bacteria, but it does not by itself distinguish between latent TB infection and active tuberculosis disease. Clinical evaluation and additional testing are needed to make that distinction.
