title: [How effective are tests for avoiding contrast reactions].
abstract: The frequency of known severe and fatal reactions after intravenous injections of biligrafin forte were compared during two periods. During the first period test ampules were provided; during the second period, the test ampules were no longer made. It was shown that the failure to perform tests did not result in any increase in the complication rate when compared with the period when test ampules were available. The problems arising from this comparison are discussed.
