What Is a TB Blood Test?
The TB blood test (IGRA – Interferon-Gamma Release Assay) is used to detect tuberculosis infection by measuring your immune system’s response to TB bacteria. Unlike the skin test, this method does not require a return visit and is not affected by prior BCG vaccination.

Our TB blood test requires only one appointment, saving you time and eliminating the need for a return visit for result reading.
Enjoy competitive self-pay rates with no hidden fees, making high-quality TB testing accessible for every patient.
We use trusted certified laboratories to deliver highly accurate results with official documentation for work, school, or immigration.
With a convenient Las Vegas location and flexible scheduling, you can get tested on your time — fast and stress-free.
Doctors, nurses, medical assistants, and other healthcare workers often require a TB blood test for employment, annual screenings, and hospital credentialing.
The TB blood test is commonly used for immigration medical exams and long-term visa applications due to its accuracy and single-visit convenience.
College students, nursing, dental, and allied health program participants need TB testing before starting classes or hands-on clinical rotations.
Patients who received the BCG vaccine are ideal candidates for a TB blood test because it provides accurate results without false positives.
