Comparative studies on tuberculin testing

ABSTRACT

The relative sensitivity of tuberculin testing was studied with the use of a commercial preparation of Vollmers Patch, Mantoux 0.1 mg. OT, and first strength dose (0.00002 mg.) Purified Protein Derivative, and 1.0 mg. OTIt was found that the Vollmers Patch is almost as sensitive as Mantoux 0.1 mg. and better than first strength dose of PPD, but about 16.6% less sensitive than 1.0 mg. OTIn spite of some minor objections, the patch test is the method of choice to be recommended in the first testing for tuberculin reaction. It should be followed by either 1 mg. OT, or 0.002 (1/2 second strength dose) of PPD. (Summary and Conclusion)
