Interference of cefoxitin in the creatinine estimation and its clinical relevance.
Serum creatinine and creatinine clearance were measured in 10 healthy volunteers before and after an intravenous injection of 2 g cefoxitin sodium. Results were compared with in vitro work which demonstrated a positive interference by cefoxitin in the Jaffé reaction, the routine laboratory method of creatinine measurement. The serum creatinine estimation should be delayed until at least 2 hours...
متن کاملCatecholamine interference in enzymatic creatinine assays.
BACKGROUND Enzymatic creatinine assays are routinely used in clinical laboratories to provide more accurate estimated glomerular filtration rates and to avoid a perceived lack of analytical specificity associated with picrate (Jaffe) methods. Negative interferences with the enzymatic creatinine assay, which we noted in several patients on dopamine or dobutamine, prompted our further investigati...
متن کاملMore on cephalosporin interference with creatinine determinations.
Several cephalosporin antibioticscephalothin, cephaloglycine, cephaloridine, cephacetrile, and cefoxitinreportedly interfere positively with measurement of creatinine by the Jaff#{233} reaction. Others such as cefazolin, cephalexin, cephradine, cefamandole, and cephalpirin give negative or only very slight responses under the same in vitro conditions (1, 2). Rankin et al. (3) showed in vivo int...
متن کاملBilirubin interference in kinetic creatinine determination.
194 CLINICAL CHEMISTRY, Vol. 25, No. 1, 1979 gas chromatography before and after acid (6 mol/L HC1) and alkaline (NaOH) hydrolysis. We frequently observe a peak in the lactic acid position after alkaline hydrolysis. After acid hydrolysis of the same urine no lactate isobserved, but a peak appears in the position of levulinic acid. The mass spectra of these two peaks were identical with those of...
متن کاملBagnoud and Reymond: Interference of metamizol on creatinine determination
In order to eliminate positive interferences that take place with the Jaffe technique, the Kodak Ektachem and Boehringer Mannheim Companies have chosen an enzymatic method for the determination of creatinine in serum and urine. Pathological and clinical samples often contain metabolites in elevated concentrations or exogenous compounds such as drugs or toxic compounds. We noticed that patients ...
