[What value does laboratory diagnosis have in acute abdomen?].

1. We found in a prospective study with routine laboratory tests: As a single test only amylase is of certain value, but there are 27% false positive results in peritonitis and intestinal obstruction. 2. Our standardized program can help to evaluate disturbed vital functions and so far improve pre- and postoperative treatment. 3. A high risk is given by simultanously alterated acid-base-balance, blood sugar and creatinine; but these findings are showing shock, not acute abdomen. 4. Laboratory procedures are of no help to the practitioner; they must not delay the early lifesaving operation.
