Streptomycin interference in Jaffe reaction - possible false positive creatinine estimation in excessive dose exposure.

To study the potential of commonly used aminoglycoside antibiotics to form non-creatinine chromogen with alkaline picrate reagent. We studied the non-creatinine chromogen formation of various concentrations of streptomycin, amikacin, kanamycin, netilmicin, gentamicin and tobramycin added to known creatinine concentrations by the Jaffe reaction based creatinine estimation. Only streptomycin above therapeutic concentrations of 10mg/mL interfered in the Jaffe reaction and acted as non-creatinine chromogen. Therapeutic doses of the aminoglycosides do not form non-creatinine chromogens. Copyright © 2012 The Canadian Society of Clinical Chemists. Published by Elsevier Inc. All rights reserved.
