ABSTRACT
Objective To compare the coherence of serum creatinine,creatinine clearance(Ccr), Cystatin C,and estimated glomerular filtration rate(eGFR)in each stage of chronic kidney disease(CKD) patients.Methods Creatinine in serum and urine were determined by Jaffe method;serum Cystatin C was measured by particle enhanced turbidimetric method,while eGFR was calculated using the abbreviated Modification of Diet in Renal Disease(MDRD)equation which was mainly based on the serum creatinine concentration.According to the American national kidney foundation-Kidney Disease Outcome Quality Initiative(NKF-K/DOQI)guideline,all cases were grouped by eGFR into 5 stages.Results In these 228 cases,as eGFR decreased gradually,the average levels of creatinine and Cystatin C increased,while Ccr decreased.The level of each items showed a statistic difference among each stage(P0.05);in eGFR 60-89 ml/min group,the average level of creatinine was 83.3 ?mol/L,the abnormal rate was only 6.8%,it was not a sensitive marker to detect the slightly damaged GFR,the levels of Ccr and Cystatin C showed a marginal decrease and increase,with an abnormal rates of 70% and 86%,there was a statistic difference among the three abnormal rates(P
