TB Gold QuantiFERON Test

What is TB Gold QuantiFERON Test

TB Gold QuantiFERON Test is a blood test that is used to detect latent or active tuberculosis (TB) infection. This modern technique assesses the immune system's reaction to tuberculin germs in the blood, as opposed to the conventional skin test. It functions by monitoring the release of interferon-gamma (IFN-γ) in response to exposure of blood cells to tuberculosis antigens. Because of its high sensitivity and specificity, this test is an effective choice for diagnosing tuberculosis infections, particularly in those who have had the BCG vaccination, which may affect the results of skin tests.

TB Gold QuantiFERON Test Procedure

A tiny blood sample from the patient is taken as part of the TB Gold Quantiferon Test procedure. After incubating the sample with particular TB antigens, the quantity of IFN-γ that the blood cells produce is quantified. There is a tuberculosis infection if the immune cells identify the TB antigens and generate IFN-γ. Unlike the skin test, which takes two trips to complete, the test can be finished in one visit. The findings are usually available in a few days and offer a prompt and precise diagnosis to guide additional testing and therapy in medicine.
