 The incidence of type 2 diabetes mellitus is rapidly increasing, with many complications pressured on the health care system. Complications of diabetes due to chronic hyperglycemia related to other metabolic disorders, causing damage to the microvascular system. Among them, damaged kidney vessels lead to impair the renal function as diabetic nephropathy is the most common cause of end-stage renal disease. Measurement of glomerular filtration rate (GFR) is an important parameter in assessing renal function. In Vietnam’s hospital, serum creatinine is the biomarker mostly used to assess GFR. However, this biomarker is affected many factors such as gender, age, ... Many studies showed that serum Cystatin C is another biomarker that can detect early decline in GFR, less affected by other factors. Therefore, we conducted this study to explore serum cystatin C and creatinine levels in patients with type 2 diabetes and initially compare GFR in applying formulas of CKD.EPI 2012 and age and sex factors with these two biomarkers on those patient groups. The prospective, descriptive, cross-sectional study was performed on 50 patients with type 2 diabetes. Serum Cystatin C, serum creatinine test was performed and GFR was estimated by CKD.EPI 2012 equation. The results showed that the average serum Cystatin C level of the study group was 0.87 ± 0.24 mg/L that expressed no difference between two genders, and significant difference between age groups. Whereas, the average serum creatinine level of the study group was 81.30 ± 19.70 µmol/L, significant difference between male and female but not difference between age groups. In patients with GFR <60 mL/min/1.73m2, serum creatinine and cystatin C levels were higher than normal but there was no difference with the upper limit in the normal reference range of the two indications.
