Investigation of False-Positive Results Given by the QuantiFERON-TB Gold In-Tube Assay JOURNAL OF CLINICAL MICROBIOLOGY Slater, M., Parsonnet, J., Banaei, N. 2012; 50 (9): 3105-3107

Abstract

We investigated a sudden increase in the rate of positive QuantiFERON-TB Gold In-Tube results from 10% to 31% at a U.S. academic institution. Direct comparison of the TB antigen tubes with tubes from a different lot number identified that a potential problem with the TB antigen vials in a certain tube lot was the likely cause of the elevated positive rate. The underlying defect remains unknown. This finding warrants refinement of quality control programs by the manufacturer and users.
