We studied the positive response rate with QuantiFERON-TB GOLD In-Tube in patients with Mycobacterium avium complex disease. We evaluated 62 subjects with M. avium complex disease. QuantiFERON-TB GOLD In-Tube was performed for all the subjects. The positive response rate with QuantiFERON-TB GOLD In-Tube and the history of pulmonary tuberculosis in patients who showed a positive response were evaluated. Seven patients (11.3%) showed a positive response with QuantiFERON-TB GOLD In-Tube. These patients were elderly (age, 72-87 years) and had a history of pulmonary tuberculosis. Eleven other patients with a history of pulmonary tuberculosis showed a negative response with QuantiFERON-TB GOLD In-Tube. Half or less than half of the elderly patients with M. avium complex disease and a history of pulmonary tuberculosis showed a positive response with QuantiFERON-TB GOLD In-Tube.
