OBJECTIVE To assess the diagnostic accuracy of random urine protein-creatinine (P/C) ratio for prediction of significant proteinuria in preeclampsia as an alternative to the time-consuming 24-hour urine protein collection. METHODS Retrospective record analysis was performed on 140 pregnant women who were admitted with suspicion for preeclampsia from January 2006 to June 2011. Random urine pro...

The urinalysis is an important step in the diagnostic workup of patients with kidney diseases. The assessment of the urine includes evaluation of its physical characteristics (colour, clarity and volume), the measurement of biochemical parameters using dipstick tests (urine pH, blood, glucose, ketones, bilirubin, urobilinogen and protein) and importantly the evaluation of the sediment by phase ...

INTRODUCTION Measurement of the protein content in a 24-hour urine sample is the definitive method of establishing the presence of abnormal proteinuria. However, the urine collection is cumbersome. The spot urine protein to creatinine ratio seems to be a reliable diagnostic tool for urine protein measurement. OBJECTIVE Our aim was to evaluate the spot urine protein/creatinine ratio against 24...

OBJECTIVE To find shortest and reliable time period of urine collection for determination of proteinuria. MATERIALS AND METHODS It is a prospective study carried out on 125 pregnant women with preeclampsia after 20 weeks of gestation having urine albumin >1 using dipstick test. Urine was collected in five different time intervals in colors labeled containers with the assistance of nursing sta...

BACKGROUND The urine protein:creatinine ratio (UPC) is used to quantify urine protein excretion and guide recommendations for monitoring and treatment of proteinuria. HYPOTHESIS/OBJECTIVES Home urine samples will have lower UPCs than hospital samples. The objectives were to compare UPCs of samples collected in each setting and to determine whether environment of sample collection might affect...

The objective was to study the impact of birth weight on the relationship between ambulatory blood pressure and urinary sodium excretion in children and adolescents. The study included 134 healthy children (61 boys), all Caucasians, who were born at term after a normotensive pregnancy. For each subject, a 24-hour ambulatory blood pressure monitoring and a complete urine collection were simultan...

BACKGROUND Current UK guidelines for the identification, management and referral of chronic kidney disease advise an early-morning urine sample for the albumin:creatinine ratio or the protein:creatinine ratio (PCR) in order to quantify proteinuria. Estimated protein output (EPO) is an alternative and possibly better method of quantifying proteinuria which takes lean weight into consideration. ...

Background and Objectives. This study proposes a novel urine collection device that can divide each urine collection into 20 parts and store and cool just one part. The aim of the current study is to compare measured biomarkers from the proposed urine collection device to those of conventional 24-hour sampling method. We also hypothesized that the new method would significantly increase patient...

Are overnight urine specimens adequate for characterizing the daily salt intake of individuals, i.e., can the overnight specimen replace the 24-bour specimen? Data from 142 male participants of an ongoing trial on the primary prevention of hypertension were used to examine this question with correlation analysis and quantile classification. Estimated correlation between the true mean 24-hour an...
