About the TB Gold Blood Test - QuantiFERON Tuberculosis Lab Test
A tuberculosis blood test, or interferon-gamma release assay, checks whether the immune system has been exposed to the bacterium that causes TB. It measures the release of interferon-gamma after blood is mixed with specific TB antigens. Clinicians use it to screen people at risk, test close contacts, and check healthcare or travel-related exposure without a skin test.
What this test measures
- Interferon-gamma response to TB antigens (ESAT-6, CFP-10, TB7.7) A marker of immune sensitization to TB, measured by an interferon-gamma release assay.
Who this test may be right for
- People with close contact with someone who had TB.
- Individuals from or traveling to areas where TB is more common.
- Healthcare and other workers with TB exposure risk.
- People with weakened immune systems.
- Those being screened before certain procedures or medications.
Before your visit
- No fasting is required for a TB blood test.
- Take usual medications unless told otherwise.
- Tell the provider about prior TB tests or treatment.
- A standard blood draw is used; the sample must be processed promptly.
- Share any immune conditions or medications that could affect results.
Understanding your results
A positive interferon-gamma result indicates the immune system has likely been exposed to TB and usually prompts further evaluation for active or latent infection. A negative result makes exposure less likely but can be affected by immune status and timing. The test does not distinguish latent from active TB by itself. Discuss the result with a healthcare provider.
