Lack of interference with creatinine assays by four cephalosporin-like antibiotics.

Some cephalosporin-like antibiotics have been shown to interfere with creatinine assays performed by the commonly used Jaffe methods. The authors show that four new drugs of this type--moxalactam, cefoperazone, cefotaxime, and ceftazidime--do not interfere with this test. A table is presented summarizing all literature data regarding interference with creatinine assays of cephalosporin-like drugs.
