Tuberculosis Blood Test
Tuberculosis (TB) is a contagious bacterial infection caused by Mycobacterium tuberculosis. While it most commonly affects the lungs, TB can also involve other parts of the body. The ICare Tuberculosis (TB) Blood Test is an advanced screening test that helps detect TB infection, including latent tuberculosis infection (LTBI), before symptoms develop.
Unlike the traditional tuberculin skin test (TST), the TB blood test requires only one visit, is not affected by prior BCG vaccination, and provides highly accurate results. Whether you need testing for employment, school, healthcare requirements, travel, immigration, or personal health, the ICare TB Blood Test offers a convenient and reliable solution.
With ICare's concierge mobile laboratory services, professional TB screening is delivered directly to your home, office, or preferred location with the personalized care and convenience you deserve.

What Does This Test Measure?
The Tuberculosis (TB) Blood Test is an Interferon-Gamma Release Assay (IGRA) that measures your immune system's response to proteins from Mycobacterium tuberculosis.
Common IGRA tests include:
QuantiFERON®-TB Gold Plus (QFT-Plus)
T-SPOT®.TB
When blood cells are exposed to TB-specific proteins in the laboratory, the test measures the release of interferon-gamma (IFN-γ), an immune signaling protein.
A positive immune response suggests that your body has been infected with the TB bacteria.
Unlike the tuberculin skin test, IGRA testing is:
Not affected by prior BCG vaccination
Less likely to produce false-positive results related to most non-tuberculous mycobacteria
Completed with a single blood draw and no return visit for test interpretation
