[The tuberculin-transamidinase test--a new method for the diagnosis of renal tuberculosis]

The possible use of the provocative standard test with subcutaneous administration of tuberculin combined with determination of the activity of transamidinase, a renal specific enzyme, in the serum and urine before and 24, 48, 72 and 96 hours after administration of tuberculin was studied for the first time in 63 patients with a purpose of diagnosing nephrophthisis. It was shown that a 2-fold or higher increase in the transaminidase activity in response to subcutaneous administration of 50 TU during the period from 24 to 72 hours could serve as a sign of nephrophthisis.
