Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestThe QuantiFERON TB Gold blood test is an interferon-gamma release assay used to detect infection with Mycobacterium tuberculosis, the bacterium that causes tuberculosis. Unlike skin testing, this laboratory method requires a single blood draw and measures the immune system's response to specific TB antigens in a controlled ex vivo setting.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Algonquin
The QuantiFERON TB Gold test assesses cell-mediated immunity to TB without the need for a second visit or skin interpretation.
The assay works by incubating a sample of whole blood with synthetic peptides that correspond to proteins found in Mycobacterium tuberculosis. If the person has been infected, their T lymphocytes release interferon-gamma in response to these peptides. The laboratory then quantifies that interferon-gamma to produce a measurable result.
Because the test uses antigens that are absent from most non-tuberculous mycobacteria and from the BCG vaccine, it offers a more specific signal than traditional tuberculin skin testing in many situations. This specificity helps reduce false-positive results related to prior BCG vaccination or exposure to certain environmental mycobacteria.
The QuantiFERON TB Gold test is typically ordered when a clinician needs to evaluate for latent or active tuberculosis infection. Results are reported as positive, negative, or indeterminate, and an indeterminate result may reflect an immune response that cannot be reliably interpreted, sometimes prompting repeat testing.
