Queries about this test
- Ans: A positive result on the Quantiferon TB Gold Test indicates that you have been infected with the bacteria that causes tuberculosis. It does not necessarily mean that you have active tuberculosis or are contagious to others.
- Ans: Unlike traditional TB tests that require waiting for weeks, the Quantiferon TB Gold Test delivers results within 24 to 48 hours.
- Ans: The test works by measuring the response of your immune system to specific antigens associated with Mycobacterium tuberculosis, the bacteria that causes TB.
- Ans: टेस्ट माइकोबैक्टीरियम ट्यूबरकुलोसिस, टीबी का कारण बनने वाले बैक्टीरिया से जुड़े विशिष्ट एंटीजन के प्रति आपकी प्रतिरक्षा प्रणाली की प्रतिक्रिया को मापकर काम करता है।
- Ans: Yes, QuantiFERON-TB Gold detects latent TB infection by measuring immune response to TB proteins. It cannot distinguish between latent and active TB, so further tests are needed to confirm active disease.
- Ans: No fasting is required before a QuantiFERON-TB Gold test. You can eat, drink, and take medications normally beforehand, as food intake doesn't affect this blood-based TB immune response test.
- Ans: An indeterminate result means the test couldn't reliably detect immune response, often due to weak immune function or technical issues. Retesting or further evaluation is usually recommended by your doctor.
- Ans: No, prior BCG vaccination does not affect QuantiFERON-TB Gold results. Unlike the skin TB test, this blood test uses TB-specific antigens, avoiding false positives caused by BCG vaccination history.
- Ans: A positive result indicates TB infection (latent or active). Doctors typically order chest X-rays, symptom evaluation, and possibly sputum tests to determine if it's active disease requiring treatment.
