Abstract

A patient with false elevation of serum creatinine level due to 5-fluorocytosine (5-FC) is reported. 5-FC interferes with the enzymatic method used for creatinine determination in the Kodak Ektachem analyzer. Clinicians should be aware of the potential for spurious azotemia in patients receiving 5-FC therapy for fungal urinary tract infections.
