One of the cardinal findings of the renal diseases is proteinuria, which appears in the early phase of kidney diseases and is very important in diagnosis, prognosis and decision making in the treatment process and results of the treatment. The study subjects were 126 patients who visited the nephrology department of Kangbuk Samsung Hospital. Serum was requested for urine protein electrophoresis. Total protein was measured with Bayer Advia 1650 (Biuret). Quantitation of each fraction was done by multiplying the percentage of each fraction by the total protein. Serum creatinine and BUN were also measured with Bayer Advia 1650 (Jaffe and Urease). Serum protein EP was done with REP(rapid electrophoresis) using Helena Kit reagents (REP Ultra SPE Kit, Ponceau S stain, Acetic acid, Methanol, EP Control). Concentrated urine was used for urine protein EP. The SPSS package was used for statistics analysis. Percentage and quantitation of the level of albumin in renal diseases were significantly lower than those in healthy controls. Total protein was correlated with albumin. In terms of proportion, α1-globulin, α2-globulin, β-globulin, and γ-globulin fractions were increased in the disease group. But, in the quantified level, α2-globulin was increased and β -globulin and γ-globulin were decreased. ESRD patients showed an increased secretion of high molecular proteins in urine protein EP. A decreased level in serum total protein correlated with the decreased level of serum albumin and the total amount of urine total protein. This study revealed the variety in the level of serum and urine proteins and their subgroups by EP.
