Serum lactic dehydrogenase (LDH), glutamic oxaloacetic transaminase (GOT), and amylase levels were determined in 76 chronically uremic patients. Serum LDH was increased in 77% of 486 determinations, and only 10% of the abnormal levels could be accounted for by pathological conditions known to increase LDH. Serum GOT levels were generally normal. Serum amylase was increased in 32% of 175 determinations. There is a high incidence of abnormal LDH and amylase levels in uremic patients. We caution against overinterpretation of these findings and the costly and often unnecessary search for their significance.
