In the context of our patient population, the T-SPOT.TB assay is likely to be most useful in evaluation of patients with a positive TST, since these patients have a higher pretest probability of having LTBI. It is equally likely that the low prevalence of LTBI in this low-risk population led to an increase in the false-positive rate despite the high sensitivity and specificity of the T-SPOT.TB assay. Patients with a positive T-SPOT.TB test did not have typical risk factors for LTBI based on clinical evaluation.ĬONCLUSION: The lack of concordance between the TST and the T-SPOT.TB assay may indicate that the immunoassay is more sensitive, particularly in a patient population taking immunosuppressive medications. Among these 179 subjects, 2 had a positive TST and 10 had a positive T-SPOT.TB test. All subjects had a strong response to the T-SPOT.TB test positive control, and there were no indeterminate results. rapidly progressive disease with life-threatening extra-articular symptoms. RESULTS: Both tests were performed on 179 subjects, who had no history of a positive TST. Table 23.3 LiSt oF PHARMAcoLoGic AGentS coMMonLY USeD FoR tHe. A medical history was obtained using a questionnaire, whole blood was drawn for the T-SPOT.TB assay, and tuberculin skin testing (TST) was performed.
