What is an IGRA Test in Varanasi?
The IGRA Test in Varanasi (Interferon Gamma Release Assay) is a simple blood test used to detect latent tuberculosis (TB) infection. It measures your immune system’s response to Mycobacterium tuberculosis–specific antigens.
Unlike the older Tuberculin Skin Test (TST), the IGRA test requires only one visit and is not affected by BCG vaccination, making it ideal for accurate TB screening. It helps identify individuals exposed to TB bacteria, even when they show no symptoms.
What Does an IGRA Test Measure in Varanasi?
The test measures the release of interferon-gamma (IFN-γ) by your white blood cells when exposed to TB-specific antigens.
It helps:
- Detect latent TB infection: Identifies previous exposure to TB bacteria.
- Differentiate TB from BCG response: Avoids false positives caused by prior vaccination.
- Assess immune function: Especially useful for those with weakened immunity.
- Support TB contact tracing: Screens individuals exposed to active TB cases.
- Guide preventive care: Determines if you need preventive anti-TB medication to avoid future disease.
Who Should Consider an IGRA Test?
Your doctor may recommend the IGRA test if you:
- Have been in close contact with a person who has active TB.
- Have tested positive in a TB skin test and need confirmation.
- Have a weakened immune system due to conditions like HIV, diabetes, or kidney failure.
- Are preparing for organ transplant or immunosuppressive therapy.
- Work in healthcare or laboratory settings with potential TB exposure.
- Have received the BCG vaccine but still need TB screening.
What Is the Purpose of an IGRA Test?
The IGRA test identifies whether you have been infected with TB bacteria, even if you have no symptoms. Early detection allows for timely preventive treatment, helping reduce your risk of developing active TB in the future.

Guide to Interpreting IGRA Test Results
What Your IGRA Test Results May Indicate
| Result | Interpretation | Meaning |
|---|---|---|
| Negative | TB infection unlikely | No signs of latent or active TB infection. |
| Positive | Possible latent TB infection | Indicates exposure to TB bacteria; further tests needed to confirm. |
| Indeterminate | Inconclusive | May be due to technical issues or weak immune response; repeat testing recommended. |
Note:
A positive IGRA result indicates TB exposure but does not diagnose active disease. Follow-up with chest X-ray or sputum tests may be required.
Understanding Abnormal IGRA Test Results by Parameter
| Parameter | High Values May Indicate | Low or Indeterminate Values May Indicate |
|---|---|---|
| Gamma Interferon (Antigen Tube) | Immune response to TB antigens – possible latent infection | No detectable response or technical interference |
| Gamma Interferon (Mitogen Tube) | Normal immune activity | Possible immune suppression or poor sample quality |
What Preparations Are Needed for an IGRA Test?
Follow these simple steps to ensure an accurate result:
- No fasting required: Eat and drink normally before your test.
- Inform your doctor: Share details about current medications, chronic illnesses, or recent vaccinations.
- Avoid recent infections: If you’ve had flu, measles, or pneumonia recently, consult your doctor before testing.
- Provide medical history: Include any previous TB exposure, treatment, or vaccination details.
- Stay relaxed and hydrated: Drink water before your test to make the blood draw easier.
