An interleukin 2 binding factor in human serum.

CLINICALCHEMISTRY, Vol. 34, No. 3, 1988 595 limit for creatine, i.e., for men 4 mgfL, and for women 7 mg/ L. As expected, samples with a higher creatinine concentration require less creatine for this interference to be manifested. Evidently creatine interference has no substantive impact on the clinical utility of the Kodak Ektachem single-slide method, because any flagged value is automatically diluted as a part of the routine protocol. Indeed, a “Substrate Depletion” flag should alert one of a possible creatine abnormality and the associated clinical implications, e.g., rhabdomyolysis or other disorders involving destruction or wasting of muscle mass and associated renal failure.
