An assay of creatine in human serum using an HPLC with UV detection

Popis výsledku v původním jazyce

An ion-exchange high-performance liquid chromatography with ultraviolet detection for the determination of creatine in human serum has been developed. The human serum was deproteinized with perchloric acid. For the separation, a cation-exchange column LC-SCX, 250 mm x 4.6 mm, 5 um, was used. The mixture of ethanol and 10mmol l-1 ammonium acetate (15:85, v/v), pH 4.00+/-0.05 was used as a mobile phase. The analytical performance of this method is satisfactory: the intra-assay and inter-assay coefficientsof variation were below 10%. Quantitative recoveries of spiked serum samples were between 97.1% and 103.5%. The calibration curve was linear in the whole range tested. The limit of quantification was 2 umol l-1. The preliminary reference ranges of serumcreatine in a group of blood donors are 17-89 umol l-1 for women and 21-97 umol l-1 for men.
