Popis: Background: Chronic Kidney Disease (CKD) is a global health problem with rising incidence. Serum Creatinine (SCr) is insensitive to moderate reductions in Glomerular Filtration Rate (GFR). Low molecular weight proteins like Beta2-Microglobulin (BMG) are cleared by the plasma through glomerular filtration. Hence serum concentrations increase progressively with reduction of GFR. Aim and Objectives: To correlate serum concentrations of BMG with creatinine and estimated GFR (eGFR) in patients with early stages of CKD. Material and Methods: Seventy four adults in early stages of CKD were included based on eGFR, calculated using the 4 variable Modification of Diet in Renal Disease (MDRD) equation and albumin creatinine ratio. They were divided into four groups based on the stages of CKD. SCr was measured using Jaffes reaction with Rosche Hitachi P800 autoanalyser and serum BMG was measured using Calbiotech ELISA kit and compared using one way ANOVA, followed by post hoc Tukey’s test and Pearson’s correlation tests with SPSS version 16 software. Results: Levels of serum BMG were significantly elevated in all groups, (p60 ml/min/1.73 m2. Both BMG(r=-0.792) and SCr(r=-0.913) increased with reduction of eGFR (p
