Reference Interval for Renal Profile parameters in North Indian Population from Rajasthan

Dharmveer Yadav, Monika Gupta, Sandhya Mishra, Praveen Sharma


Objective: Reference intervals are an essential part of laboratory medicine. Current study was planned to evaluate renal parameters in the healthy defined group of individuals which would serve as reference values of renal parameters for the North Indian population from Rajasthan.

Design & Methods: Present study was conducted on 2021 apparently healthy individuals of North Indian origin ranging in age from 15-60 years, were selected randomly using defined criteria. Fasting samples were analyzed for Urea, Creatinine, Uric Acid, Sodium, Potassium and Chloride. Data were analyzed for middle 95 percentile (2.5th-97.5th percentile), median and 95% confidence interval using SPSS software package version 10.0.

Result: RI for Urea, Creatinine and uric acid were lower in female (16-42mg/dl, 0.6-1.2mg/dl, 2.4-6.8mg/dl) as compared to male (17.00-44.35mg/dl, 0.7-1.5mg/dl, 2.8-7.2mg/dl). There was a progressive increase in urea, uric acid and Creatinine with increase in age. Though no appreciable differences could be observed in respect to most of renal parameters in rural versus urban, a wider range for uric acid was observed in urban population (2.50-7.20mg/dl). Except for Na+, K+ and Cl-, rest of parameters i.e. urea, creatinine, uric acid were higher range in obese as compared to non obese (17-45 Vs 17-44, 0.66-1.5 Vs 0.60-1.40, 2.5-7.4 Vs 2.5-7.0). Uric acid level was also found to be higher in non vegetarian population (2.6-7.5mg/dl).

Conclusion: Findings of this study provide sex, age, BMI, habitat and diet specific renal function reference values to be used for North Indian population.
