The QuantiFERON tuberculosis lab test, often called the TB Gold blood test, is a blood-based method for detecting infection with Mycobacterium tuberculosis, the bacterium that causes tuberculosis. Unlike skin testing, this assay measures the immune system's response in a blood sample, which can simplify interpretation for many patients and providers.

About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in San Clemente

This test is used to identify whether a person has been infected with the tuberculosis bacterium.

Tuberculosis spreads through the air when a person with active respiratory disease coughs, speaks, or sings. Many people who inhale the bacterium do not become ill immediately; instead, the immune system contains the infection in a dormant state, known as latent tuberculosis infection.

The QuantiFERON assay works by mixing a blood sample with specific antigens derived from Mycobacterium tuberculosis. If the person's immune cells have encountered the bacterium before, they release a signaling molecule called interferon-gamma. The laboratory measures the amount of interferon-gamma produced, which helps indicate whether an infection is present.

This blood test does not distinguish between latent infection and active tuberculosis disease. A positive result generally means the immune system has been exposed to the bacterium at some point. Additional evaluation, including symptoms, imaging, and other laboratory work, is needed to determine whether the infection is latent or active and to guide appropriate care.
