Measurements of protein-to-creatinine ratios in single-voided urine samples were compared with 24-hour urinary protein excretions for quantitation of proteinuria in inpatients and outpatients. Patients included those representing a broad spectrum of renal diseases, a wide range of proteinuria, and various degrees of reduction in glomerular filtration rate. Protein-to-creatinine ratios in single-voided urine samples correlated well with measurements of 24-hour urinary protein. This simple single-voided test is reliable and useful in the screening, assessment, and follow-up of proteinuria and avoids the problems associated with 24-hour urine collection.
比较了单次晨尿样本中蛋白质与肌酐的比值与24小时尿蛋白排泄量，以定量住院患者和门诊患者的蛋白尿。患者包括患有广泛肾脏疾病、蛋白尿范围广泛以及肾小球滤过率不同程度降低的人群。单次晨尿样本中的蛋白质与肌酐比值与24小时尿蛋白测量值相关性良好。这种简单的单次晨尿检测在蛋白尿的筛查、评估和随访中可靠且有用，并且避免了与24小时尿液收集相关的问题。
