[The effect of iodine-containing radiographic contrast medium on TSH-TRH-tests (author's transl)].
In the course of an investigation of TRH-tests, 340 TSH-tests were performed in 120 patients before and after the administration of various iodine-containing radiographic contrast media in order to determine a possible effect on the TRH-tests. In addition, the peripheral thyroxin level and RIA-T3 content of the serum was determined. Mean TSH rise following TRH (delta-TSH) showed no significant difference before and after the contrast medium. Individual variations were, however, observed. In view of these results, it is concluded that the TRH-test provides reliable information after iodine exposure.
