Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestThe TB Gold blood test, also known as the QuantiFERON tuberculosis lab test, detects whether a person has been infected with the bacterium that causes tuberculosis. Unlike skin tests that require a follow-up reading, this assay uses a single blood draw to measure the immune system's response to specific TB proteins.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Wasco
Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis, a bacterium transmitted through the air when a person with active respiratory TB coughs or sneezes.
The QuantiFERON TB Gold test works by mixing a blood sample with synthetic peptides that mimic proteins found in M. tuberculosis. If the person's immune cells have encountered the bacterium before, they release interferon-gamma, a signaling molecule that the test detects and quantifies.
This approach distinguishes TB infection from most nontuberculous mycobacteria and from the BCG vaccine, which can cause false-positive results on older skin tests. Because it relies on a blood draw rather than an intradermal injection, it avoids the need for a return visit to have the site examined.
Results are typically reported as positive, negative, or indeterminate. A positive result indicates that the immune system has been exposed to TB proteins, but it does not by itself distinguish between latent infection and active disease. Clinical evaluation and additional testing are needed to make that determination.
