What Is the TB Blood Test?
The TB blood test, often called IGRA (Interferon-Gamma Release Assay), is a modern alternative to the traditional skin test. It measures how your immune system reacts to TB bacteria in your bloodstream—offering fast, accurate results with just one visit.
We offer the QuantiFERON-TB Gold Plus test, which is approved for use in all situations requiring TB screening.
Why Choose the TB Blood Test?
- No return visit required
- BCG vaccine-friendly (no false positives)
- Accepted for employment, school, and immigration
- More accurate than the PPD in many cases
Who Should Get a TB Blood Test?
- Individuals vaccinated with BCG
- Those with busy schedules (no return visit needed)
- Employers or agencies requiring lab-based TB results
We make it easy with quick blood draws, fast lab processing, and official documentation.
