The Survey of the Turbidity Interference Rate in 24-Hour Urine Protein Measurement before and after Cold Treatment in Centrifuged Samples

Introduction and Aims: Proteinuria means the presence of an excess of serum proteins in the urine that is very important to achieve accurate and reliable results to the physicians. The aim of this study was to evaluate the interference of turbidity in the measurement of 24-hour urine protein before and after cold treatment in turbid centrifuged samples.
This experimental study was performed in ACECR (Academic Center for Education, Culture and Research), that was conducted on a random sample of 1000 people in 2015 March to September. The measurement of 24-hour urine protein was performed by using three chloral acetic acid method (TCA) and photometer.
Ten samples (1%) just were turbid after centrifuge. There was a significant difference (P In order to deposit interfering factors, the urine samples that are taken to measure protein and are turbid after centrifuge should be given cold treatment and centrifuge again.
