Aim: To assess the diagnostic accuracy of spot urine protein-creatinine ratio for detection of proteinuria in Preeclampsia. Methods: Cross Sectional Descriptive Study was conducted in a total of 38 pregnant women in Paropakar Maternity and Women’s Hospital in study period of 3 month. The correlation between protein- creatinine ratio in spot urine samples and urinary protein excretion in 24-hour collections were analyzed. Results: Comparison of 24 hours urinary protein and protein- creatinine ratio in women with preeclampsia shows a significant correlation (r=0.911, p<0.0001). The cut-off protein-creatinine ratios which gave maximum area under the curve for 300mg protein for 24hrs was 0.27 (sensitivity: 94.6%, specificity: 100%, PPV: 100%, NPV: 33.3%); 2000 mg urine protein excretion was 2.1 (sensitivity and specificity of 100%); 3000mg protein excreted for 24hours was 3.0 (sensitivity: 83.3%, specificity: 92.3%, PPV: 83.3%, NPV: 93.3%. Area under the ROC for 24hours urine total protein of >300mg, >2000mg and >3000mg/day were 0.946 (95%CI 0.873-1.019), 1 (95% CI 1.00-1.00) and 0.957 (95%CI 0.897- 1.016) respectively. Conclusions: Spot urine protein-creatinine ratio is as accurate as to 24 hours urine protein determination of proteinuria in Preeclampsia.

Background: The aim of the study was to evaluate the ability of the random urine P/C ratio to predict significant proteinuria, as well as to introduce a diagnostic test for pre-eclampsia which will avoid the inconvenience and time consumption of 24-hour urine protein collection. The objective of this study was to compare spot urine protein- creatinine ratio with 24-hour urine protein for estimation of proteinuria in pre-eclampsia.Methods: A total of 50 pregnant women with pre-eclampsia were prospectively studied for proteinuria in Rajarajeswari medical college and Hospital Bangalore for a period of 9 months from September 2018 to May 2019. Spot urine specimens for measuring P/C ratio were obtained immediately before 24-hour urine collection. The correlation between the spot urine P/C ratio and urinary protein excretion in the 24-hour collections was examined using the Spearman correlation test.Results: PCR at a cut off value 0.15 g/mmol had sensitivity and specificity of 96.6% and 55% respectively. In prediction of proteinuria of 300 mg/24 hr positive predictive value and negative predictive value 76.3% and 91.6% respectively.Conclusions: We found that there was a strong correlation between 24-hour urine protein excretion and spot urine protein creatinine ratio in pre-eclamptic women. Spot PCR can be used as a reasonable alternative to 24-hour urine protein test which is a cumbersome.

Background: Quantification of proteinuria is usually predicted upon 24-hour urine collection. Multiple factors influence urine collection and the rate of protein and creatinine excretion. A spot urine protein-creatinine (P-C) ratio has been shown over the years to be a reliable alternative to the 24-hour collection for detection and follow up of proteinuria. The objective of the study was to evaluate the accuracy of urine protein creatinine ratio (UP/UC) in a spot sample for quantitative measurement of proteinuria in comparison with 24 hours urinary protein excretion in children of nephrotic syndrome having normal Glomerular Filtration Rate (GFR). Methodology: This was a prospective study conducted in the department of paediatrics, Sir Salimullah Medical College & Mitford Hospital Dhaka over a period of six months from January 2003. Fifty cases of Nephrotic syndrome were included who were on initial attack and relapse cases noted down into the proforma with respect to history, examination and investigation. All the patients were advised regarding 24 hours urine collection. They were asked to give a 24 hours urine sample starting at 9.00 am for total protein excretion rate. A spot urine sample was obtained and urine protein/creatinine ratio was calculated. The data was analyzed by linear regression and by calculating the correlation coefficient between urinary protein/ creatinine ratio and 24-hour urinary protein. Results: Sample size was fifty. Urine total protein in a timed 24-hour sample of nephrotic syndrome patients was in the range of 300-3150mg/m2/hour with the mean value of 1725 mg/m2/hour. While as U(Pr/Cr) ratio ranged from 3.1-27.5 with the mean value of 15.2. A significant correlation was found between timed 24-hour urinary protein and UP/UC ratio (r=0.622, p=<.001.) Conclusions: Spot urine protein-creatinine ratio is highly reliable and rapid test for quantification of proteinuria in children with nephrotic syndrome.
