The Correlation of Urine Protein/osmolality and Protein/creatinine Ratio as Predictor of 24-hour Urinary Protein Excretion.

Background: The drawback of 24-hour urine collection is that it is troublesome, takes a lot of time, and is inaccurate because of collection errors and improper timing. The research in the Indian adult population about the correlation of spot urine protein/osmolality ratio (UPOR) and spot urine protein/creatinine ratio (UPCR) as a predictor of 24-hour urinary protein excretion is lacking.

Objectives: To study the correlation of spot UPOR and spot UPCR as the prognosticator of 24-hour urinary protein excretion.
