Objective: To correlate Cystatin C with GFR and urinary albumin in order to find it out as a marker of early detection of kidney
disease (diabetic nephropathy).
Study Design: A cross sectional analytic study
Place and Duration: The Department of Biochemistry, Islamic International Medical College from 15th March, 2016 to 14th March,
2017.
Methodology: The diabetic patients having urinary albumin creatinine level between 30 mg/g to 300 mg/g were selected. The
estimation of urinary albumin levels and cystatin C levels were carried out on IMAGIN Specific Protein Analyzer. GFR was calculated
using standardized clinical and pathological parameters of creatinine levels, patients age, gender and body size and a cutoff value of
GRF of < 60 ml was set for probable nephropathy.
Results: Mean age of patients was 56.1 ± 5.4 years with male predominance (58.5%). Non-parametric spearman’s correlation
coefficient found out that GFR was negatively correlated with Cystatin C (-.305). The correlation coefficient for and Cystatin C and
urinary albumin was (0.517) showing a perfect positive linear relation.
Conclusion: Cystatin C was found significantly correlated with GFR and urinary albumin, thus, validating previous findings regarding
Cystatin C’s role as an early marker of kidney diseases.
