This test is ideal if you've been exposed to someone with tuberculosis, work in healthcare or high-risk settings like nursing homes or correctional facilities, or are traveling from countries where TB is common. It helps detect latent TB infection before it becomes active disease, which is important for protecting yourself and others. Many people use this test for employment screening, immigration requirements, or simply peace of mind after potential exposure.
No special preparation is needed for this test. You don't need to fast before your blood draw, and you can take your regular medications. Just show up to your appointment and the blood sample will be collected and processed within 16-48 hours while your white blood cells are still active.
This advanced blood test measures your immune system's response to TB-specific proteins through interferon-gamma levels. It evaluates how your white blood cells react to TB antigens, which indicates whether you've been infected with tuberculosis bacteria. Unlike older skin tests, this blood-based approach is more accurate for people who've received the BCG vaccine and only requires one visit instead of two.
What this means
Your test came back negative, meaning no TB infection was detected. This is the expected and healthy result, indicating your immune system has not been exposed to tuberculosis bacteria or that any previous exposure has been cleared.
Recommended actions
Continue practicing infection prevention if you work in healthcare or high-risk settings
Consider annual retesting if you work in environments with TB exposure
Seek testing promptly if you have close contact with someone diagnosed with TB
Maintain good overall health with adequate nutrition and sleep to support immune function
