At the same time, the differentiation between nonspecific tuberculin reactions and specific ones is understudied.Additional optimization approaches to improve test performance were examined and showed that the application of "a priori exclusions" of test results on the basis of reactivity to fortuitum PPD (sensitin produced from Mycobacterium fortuitum) and to a lesser degree, avian PPD, increased specificity without losing sensitivity (Michel et al., 2011).
