Comparison of serum levels of Cystatin-C and traditional renal biomarkers for the early detection of pre-hypertensive nephropathy.

Objective: To compare serum Cystatin-C and serum creatinine levels along with estimated glomerular filtration rate of apparently healthy people of South Asian descent with pre-hypertension to determine which is better in detecting reversible renal dysfunction.

Methods: :The comparative cross-sectional study was conducted at the Army Medical College, Rawalpindi, Pakistan, in 2013-14, and comprised apparently normal healthy male and female volunteers. The subjects were divided into normotensive group 1 and pre-hypertensive group 2.
