What is a Interferon gamma release assay (IGRA) Test in Delhi ?
What is Interferon gamma release assay (IGRA)?
Interferon gamma release assay (IGRA) measures the amount of interferon-gamma your white blood cells release after exposure to specific tuberculosis (TB) proteins. It checks whether your immune system has been sensitized to TB bacteria.
What does Interferon gamma release assay (IGRA) measure?
This matters because it helps identify latent TB infection and supports evaluation for active TB when used with other tests. Doctors use IGRA for screening after TB exposure, for people starting immunosuppressive drugs, and for high-risk workers or travelers. A positive test suggests TB infection. A negative test usually means no immune evidence of TB, but recent exposure or weakened immunity can cause false negatives.
What symptoms suggest Interferon gamma release assay (IGRA) may be needed?
A doctor may recommend Interferon gamma release assay (IGRA) when a patient reports sudden fever (above 38.5°C), body aches and chills, persistent headache, nausea or vomiting, abdominal pain, skin rash, joint pain, and extreme fatigue. Sample collection for Delhi is available at labs and at home across Saket, Punjabi Bagh, and surrounding neighbourhoods.
How is Interferon gamma release assay (IGRA) performed?
GetVisit home collection in Saket or Punjabi Bagh, Delhi: a certified phlebotomist arrives at your address at your chosen slot (available from 6:00 AM), brings all sterile single-use equipment, draws the sample, and dispatches it to the NABL-accredited lab. Your digital report is delivered to your GetVisit profile the same day for most standard blood tests.
How accurate is Interferon gamma release assay (IGRA)?
Results are analytically reliable because GetVisit's Delhi logistics network maintains proper cold-chain transport from your Saket or Punjabi Bagh collection point to the processing lab, preserving sample integrity. NABL independently audits quality control at regular intervals.
Are there any risks to Interferon gamma release assay (IGRA)?
A blood draw for Interferon gamma release assay (IGRA) is very safe. Occasionally there is minor bruising or light-headedness; sitting for a couple of minutes afterwards at the Saket or Punjabi Bagh, Delhi collection point usually prevents this.
Did you know?
An interferon-gamma release assay (IGRA) is a blood test that detects immune sensitization to Mycobacterium tuberculosis by measuring interferon-gamma released by T cells after exposure to TB-specific antigens.
Interferon gamma release assay (IGRA) Test Preparation in Delhi
Fasting and diet:
No fasting is required. Eat and drink as usual, stay well hydrated, and simply avoid alcohol and heavy exercise in the 12 hours before your appointment.
Medication:
Unless your physician advises a change, keep taking your usual prescriptions as normal.
What to bring:
Bring your doctor's prescription, a valid photo ID, and your insurance card if you're using cashless OPD. Loose sleeves make collection easier.
Timing and slots:
An early slot works best, especially for fasting tests. Home collection is available across Punjabi Bagh, Preet Vihar, and the rest of Delhi.

Why Take a Interferon gamma release assay (IGRA) Test in Delhi ?
When does a doctor order Interferon gamma release assay (IGRA)?
Interferon gamma release assay (IGRA) is used in TB screening panels for people with TB exposure risk or before immunosuppressive therapy. Doctors order it for symptoms like persistent cough, fever, night sweats, weight loss, or known contact with TB.
Who should get Interferon gamma release assay (IGRA) done in Delhi?
Delhi faces a dual infection burden. The July-to-September monsoon floods low-lying areas including Dwarka, Rohini, Shahdara, and Uttam Nagar , driving dengue, typhoid, malaria, and leptospirosis surges. Separately, Delhi's severe winter air pollution (AQI regularly 300 to 500+ from November to January in all areas) causes chronic respiratory infections, suppresses immune function, and significantly increases susceptibility to seasonal viral and bacterial illness. Anyone with fever or flu-like illness in Delhi, especially during and after the monsoon, benefits from prompt Interferon gamma release assay (IGRA) testing, as do travellers returning from endemic areas and people caring for someone already infected. Residents of Hauz Khas, Dwarka, and flood-prone localities face higher seasonal exposure to mosquito- and water-borne infections.
What conditions can Interferon gamma release assay (IGRA) help diagnose?
It helps detect latent or active TB. Abnormal results usually indicate TB infection; weakened immunity, recent exposure, or some medicines can change accuracy. A family TB history raises testing importance.
What do Interferon gamma release assay (IGRA) results mean?
Higher or positive results: A positive IGRA means you likely have been infected with Mycobacterium tuberculosis but does not distinguish latent from active disease. Your doctor reads the value against the reference range on your report and your symptoms, and may repeat a borderline result to confirm it.
How often should Interferon gamma release assay (IGRA) be repeated?
Infection tests are ordered when symptoms are present rather than on a fixed schedule. Repeat testing may be needed to confirm recovery, to check clearance after treatment, or if fever recurs. During Delhi's monsoon fever season, prompt retesting is advised for any new febrile illness.
What happens after Interferon gamma release assay (IGRA) results are ready?
Your GetVisit digital report is delivered to your phone as soon as results are authorised. Share it directly with your doctor via the app, or book a consultation with a GetVisit-verified specialist on the same platform. Critical values outside a safe range are flagged by the laboratory for urgent clinical review.
