1. What is an IGRA TB Test?
The IGRA TB (Interferon-Gamma Release Assay) is a blood test used to detect whether your immune system has been exposed to the bacteria that causes tuberculosis. It measures how your white blood cells react to TB proteins.
2. Why is an IGRA TB Test Needed?
The test is important for identifying TB infection in people without symptoms. It helps prevent the disease from spreading and is especially useful for screening healthcare workers, immigrants, and high-risk groups.
3. How is the IGRA TB Test Done?
A small blood sample is taken from your arm and sent to a lab. There, the reaction of your blood cells to TB-specific proteins is measured to determine infection.
4. Who Should Get an IGRA TB Test?
This test is ideal for people who are at risk of TB exposure but do not show active symptoms. It’s recommended for healthcare workers, travelers, immunocompromised patients, or those with positive skin tests.

5. Why is IGRA TB Done?
IGRA TB is done to detect latent tuberculosis infection in individuals exposed to TB or at high risk. It helps prevent progression to active TB disease through early diagnosis.
6. How is the IGRA TB Test Done?
A blood sample is drawn and analyzed in a lab to detect the immune system’s response to TB proteins, identifying possible latent tuberculosis infection without needing a second visit.
7. For Whom IGRA TB Should Be Considered?
This test is recommended for people exposed to TB, with weakened immunity, healthcare workers, or those from high-risk regions. It’s also used to confirm positive tuberculin skin test results.
8. Which Symptoms or Conditions Require for Monitoring?
Chronic cough, fever, night sweats, unexplained weight loss, and prior exposure to TB may require IGRA TB testing to check for hidden or latent tuberculosis infections in the body.
Need for the IGRA TB Test
The IGRA TB test is a key diagnostic tool for detecting TB infection before it becomes active and spreads to others.
1. Early Detection of TB :- The IGRA TB test helps detect infection at an early stage, even when no symptoms are present, reducing the risk of developing or unknowingly spreading active tuberculosis disease.
2. High-Risk Group Screening :- Ideal for healthcare workers, close contacts of TB patients, or individuals with weak immune systems, this test helps monitor and manage TB risk more effectively in vulnerable populations.
3. Accurate and Reliable :- Unlike traditional skin tests, IGRA TB provides more accurate results in people previously vaccinated with BCG, minimizing false positives and helping ensure patients receive appropriate treatment when truly needed.
4. One-Time Testing :- This test requires just one visit—no follow-up appointment for result reading—making it far more convenient for busy people and reducing delays in diagnosis and treatment initiation.
5. Support for TB Elimination :- By identifying hidden TB infections, this test helps prevent new TB cases, supports disease control efforts, and contributes meaningfully to global and national public health elimination strategies.

Frequently Asked Questions
Is the IGRA TB test safe for children?
Yes, it is safe for children, especially those at risk or with TB exposure. It is commonly used in pediatric TB screening.
Can the IGRA TB test confirm active TB?
No, it only detects latent infection. Further testing, like a chest X-ray, is needed to confirm active TB disease.
Do I need to fast before an IGRA TB test?
No fasting is required. You can eat and drink normally before the test.
Is the IGRA TB test better than the skin test?
Yes, it’s more accurate, especially for people who had the BCG vaccine, and doesn’t require a second visit for result reading.
What does an IGRA TB test detect?
It checks if your immune system has been exposed to TB bacteria, indicating a latent or silent infection without current symptoms.
