Test Details
Test Name : QuantiFERON TB GOLD
Code: QFTG
Test Overview : The QuantiFERON TB GOLD PLUS (QFT) blood test measures a person's immune reactivity to M. tuberculosis and can be used as an aid in diagnosing infection. The test should not be used to differentiate latent tuberculosis infection from tuberculosis disease. QFT is unaffected by previous BCG vaccination and will not give a false positive result.
Test Preparation Instructions : If you are visiting a Laboratory Health Centre call beforehand to confirm collections can be performed at the location and to secure a kit. Please allow 2 - 3 days for kit to arrive. In order to maintain the integrity of the sample, TB Quantiferon is not collected in some of our remote locations and Co-Op's. Please call your regional Help Desk or Customer Service to confirm an alternate location.
