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 کاملTwenty-Four-Hour Urine Osmolality as a Physiological Index of Adequate Water Intake
While associations exist between water, hydration, and disease risk, research quantifying the dose-response effect of water on health is limited. Thus, the water intake necessary to maintain optimal hydration from a physiological and health standpoint remains unclear. The aim of this analysis was to derive a 24 h urine osmolality (U(Osm)) threshold that would provide an index of "optimal hydrat...
متن کاملCorrelation of specific gravity and osmolality of urine in neonates and adults.
There is good correlation between the specific gravity and osmolality of urine obtained from neonates and adults, if specimens contain neither protein nor glucose. The regression equations between specific gravity and osmolality, however, differ considerably between the two age groups, maturation to the adult regression occurring within the first 5 years of life. Specifically derived regression...
متن کاملPregame urine specific gravity and fluid intake by National Basketball Association players during competition.
CONTEXT Urine specific gravity (USG) has been used to estimate hydration status in athletes on the field, with increasing levels of hypohydration indicated by higher USG measurements (eg, greater than 1.020). Whether initial hydration status based on a urine measure is related to subsequent drinking response during exercise or athletic competition is unclear. OBJECTIVE To determine the relati...
