Many people test positive for tuberculosis on the standard medical skin test. Unfortunately, there is a high rate of false positives, usually because of prior vaccination with the Bacille-Calmette-Guerin (BCG) vaccine administered for tuberculosis protection. Until the advent of blood tests like QuantiFERON Gold, people with a positive TB skin test who needed TB clearance would be required to get a chest x-ray (often annually).
