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 the bacterium that causes tuberculosis. Unlike skin testing, it relies on a single blood draw and laboratory analysis of the immune response.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Downey
The QuantiFERON TB Gold test assesses whether a person has been infected with Mycobacterium tuberculosis by measuring the body's immune reaction to specific bacterial proteins.
The test works by mixing a blood sample with antigens derived from M. tuberculosis. If the person's immune cells have prior exposure to the bacterium, they release interferon-gamma, which the laboratory measures.
Because the antigens used are not shared with most other mycobacteria or with the BCG vaccine, the test can distinguish TB infection from prior vaccination in many cases.
Results are typically reported as positive, negative, or indeterminate. An indeterminate result may occur if the immune response is insufficient for a clear interpretation, and repeat testing may be considered.
