QuantiFERON-TB Gold

QuantiFERON-TB Gold is a blood test used to detect if someone has been exposed to the bacteria that cause tuberculosis (TB). It measures the body's immune response to TB proteins by analyzing the blood sample. If the immune system reacts strongly, it suggests a possible TB infection, either active or latent. The test is quick, usually more specific than traditional skin tests, and doesn't require multiple visits. It helps doctors diagnose TB more accurately, guiding appropriate treatment decisions to prevent the spread of the disease.
