[Old and new standardized color test for the determination of aspartate aminotransferase in the differential diagnosis of heart infarct and angina pectoris].

The usability of the new and old standardized colour test for the determination of the aspartate aminotransferase (GOT) (set of test instruments VEB Arzneimittelwerk Dresden) in the differential diagnosis between acute myocardial infarction and angina pectoris are compared. Concerning this problematics the new colour test does not evoke a better separation effect than the old one. Since with the change-over there were connected considerable uncertainties in the clinic it is recommended in case of a future standardisation to publish the regions of reference and first clinical experiences before the change-over.
