TB Quantiferon Gold Test

TB Quantiferon Gold Test


The TB QuantiFERON Gold (IGRA) test is a reliable blood test that checks for TB infection without the need for a skin test. It measures how your immune system reacts to specific TB proteins, making it suitable even for people who have had the BCG vaccination. This test is widely used for TB screening in healthcare, employment, and immigration assessments. Results are objective and do not require a follow-up visit for reading.
