A 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 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 کاملA reagent strip for measuring the specific gravity of urine.
A solid-phase reagent for determination of urinary specific gravity (relative density) is described. This reagent strip, similar to others in the "N-Multistix" series (Ames), contains a polyacid whose acidity is sensitive to the ionic concentration in the urine in which it is immersed. As the acidity of the polyacid changes, pH changes are detected by a pH indicator within the reagent strip. In...
متن کاملThe Specific Gravity of the Urine in Diabetes Mellitus
or 1045." Again, we are told by another -writer that in diagnosing a case of diabetes " the density of diabetic urine, however, is one of the best indications. This fluid varies in density from 1030 to 1074 (Becquerel); but, on an average and tolerably constantly, it is 1040; and when the urinometer stands above 1030, we may suspect that sugar is present.". (Aitken's Science and Practice of Med...
متن کاملAssessment of construction workers' hydration status using urine specific gravity.
OBJECTIVES The study objective was to assess hydration status by measuring USG among construction workers in Iran. MATERIALS AND METHODS The study design was comparative and experimental. Sixty participants were randomly selected from the construction workers from a construction campus with a similar type of work, climate and diet and formed 2 groups (individuals exposed to the sun and non-ex...
