About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Gilbert
The QuantiFERON TB Gold test is an interferon-gamma release assay, commonly abbreviated as IGRA. It measures how a person's white blood cells respond when exposed to specific proteins associated with Mycobacterium tuberculosis.
Unlike the traditional tuberculin skin test, which requires a follow-up visit to read the reaction, this assay is performed on a blood sample drawn in a single encounter. The sample is incubated with antigens, and the amount of interferon-gamma released is measured to indicate whether the immune system has previously encountered TB bacteria.
Because the antigens used are specific to the tuberculosis complex, the test is designed to distinguish TB exposure from most nontuberculous mycobacteria and from prior BCG vaccination, which can complicate skin-test interpretation. Results are typically reported as positive, negative, or indeterminate, and an indeterminate result may call for repeat testing.
The test does not by itself distinguish latent TB infection from active tuberculosis disease. A positive result generally reflects infection with TB bacteria, and clinical evaluation, imaging, and additional laboratory work are needed to determine whether the infection is latent or active and to guide appropriate care.
