Dipstick measurements of urine specific gravity
Aim—To evaluate the reliability of dipstick measurements of urine specific gravity (U-SG). Methods—Fresh urine specimens were tested for urine pH and osmolality (U-pH, U-Osm) by a pH meter and an osmometer, and for U-SG by three diVerent methods (refractometry, automatic readout of a dipstick (Clinitek-50), and (visual) change of colour of the dipstick). Results—The correlations between the vis...
متن کاملUrine Dipstick Analysis
All samples should be midstream and collected in a clean sterile container. Suprapubic aspiration or fresh catheter samples are ideal, but not always practical. The gold standard method of testing is to remove a small volume of urine from the sterile container with a fresh sterile syringe, and then apply the removed urine to the dipstick. In this way, the remainder of the collected sample conte...
متن کاملA discrepant urine specific gravity.
A 21-year-old man presented after being struck by a car and underwent a computed tomography scan of the chest and spine. Three hours later, his clear yellow urine sample was sent to the laboratory. A routine urinalysis with the Roche Urisys® 2400 indicated the specific gravity (SG) as a flag, i.e., an error for SG. A manual repeat of the SG measurement was also not readable by refractometer (no...
متن کاملDipstick analysis for screening of paediatric urine.
The examination of. urine specimens constitutes a major portion of the work of a clinical microbiology laboratory. Although the prevalence of urinary tract infection varies for different patient populations, most urine specimens are culture negative. In this laboratory only 12% of paediatric urines show evidence of urinary tract infection. The availability of a rapid reliable screening test for...
متن کاملA dipstick test combined with urine specific gravity improved the accuracy of proteinuria determination in pregnancy screening.
Proteinuria screening using a semi-quantitative dipstick test of the spot urine in antenatal clinic is known to have high false-positive rates. The aim of this study was to assess availability of a dipstick test combined with the urine specific gravity for the determination of pathological proteinuria. A dipstick test was performed on 582 urine samples obtained from 283 pregnant women comprisin...
