Why the study?
Does the protein-creatinine ratio in random urine samples accurately estimate 24-hour protein excretion in patients with varying renal function and proteinuria?
Population
51 patients with a wide spectrum of renal function and proteinuria
Comparison

Supports spot protein-creatinine ratios for estimating proteinuria; leaves open prospective validation across renal function ranges.
Does the protein-creatinine ratio in random urine samples accurately estimate 24-hour protein excretion in patients with varying renal function and proteinuria?
The protein-creatinine ratio in random urine samples provides an accurate estimation of 24-hour protein excretion, offering a simpler alternative for follow-up and screening.
