Quantitation of Proteinuria by the Use of Protein-to-Creatinine Ratios in Single Urine Samples

Key Points

• The aim is to evaluate the effectiveness of protein-to-creatinine ratios in single urine samples for quantifying proteinuria compared to 24-hour urinary protein excretions.
• Compared protein-to-creatinine ratios in single-voided urine samples with 24-hour urinary protein excretion measurements.
• Included a diverse group of inpatients and outpatients with different renal diseases and proteinuria levels.
• Measured correlations between single urine samples and 24-hour collections.
• Protein-to-creatinine ratios correlated well with 24-hour urinary protein measurements.
• This method simplifies the assessment of proteinuria compared to traditional 24-hour urine collection.
• The test proves reliable for screening, assessing, and following up on proteinuria.
