Service Providers for QuantiFERON-TB Gold Plus
QuantiFERON-TB Gold Plus is a blood test used to detect latent tuberculosis (TB) infection. It measures the immune response to TB bacteria. The test involves drawing a blood sample, which is then analyzed in a lab. No special preparation is required. Risks are minimal, though rare allergic reactions or fainting may occur. During the test, you may feel a quick needle prick. Results typically take 1-2 days and are interpreted based on the presence of specific immune responses. Conditions like recent TB vaccination (BCG) may affect results, but the test is more accurate than the tuberculin skin test for certain populations.
