Start with fit
Is this the right test for you?
The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.
- ✓Individuals with symptoms suggestive of active TB (e.g., persistent cough, fever, night sweats, weight loss).
- ✓Individuals who have had close contact with a person with active TB.
- ✓Individuals with conditions that increase the risk of TB (e.g., HIV infection, diabetes, immunosuppressive therapy).
- ✓Individuals travelling to or residing in areas with high TB prevalence.
- ✓Screening for latent TB infection (LTBI) in high-risk populations.
- ✓Individuals with inconclusive results from tuberculin skin tests (TST).
In plain language
What this test helps you understand
The IGRA test detects the presence of interferon-gamma, a cytokine produced by T-cells in response to TB antigens. This response indicates whether an individual has been exposed to the TB bacteria, aiding in the diagnosis of both latent and active TB infections.
This test is recommended for individuals who have been in close contact with someone diagnosed with TB, show symptoms of TB (such as persistent cough, fever, night sweats, or weight loss), or are at high risk due to immunocompromising conditions or travel to areas with high TB prevalence.
