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. It offers a laboratory alternative to traditional skin testing and is used to identify whether a person has been exposed to the TB organism.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Pacifica
QuantiFERON technology measures the immune system's response to TB-specific antigens directly in a blood sample.
The test works by mixing a blood specimen with synthetic peptides that mimic proteins found in Mycobacterium tuberculosis. If the person's immune cells have prior experience with TB, they release interferon-gamma, a signaling molecule that the assay detects and quantifies.
Unlike the tuberculin skin test, the QuantiFERON method requires only a single blood draw and a follow-up laboratory analysis, avoiding the need for a return visit to have a skin reaction read. It also uses antigens that are absent from most nontuberculous mycobacteria and from the BCG vaccine, which reduces false-positive results related to prior vaccination.
Results are typically reported as positive, negative, or indeterminate. A positive result indicates likely infection with TB bacteria, but it does not by itself distinguish between latent infection and active disease. Clinical evaluation and additional testing are needed to make that distinction.
