A 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 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 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...

deficiency. It is not applicable to newborn or mass screening with use of ifiterpaper specimens, but is satisfactory for liquid urine screening. In one variant of sulfite oxidase deficiency, due to a defect of its molybdate cofactor metabolism, the concentration of uric acid in serum is decreased. Thus, an unexplained low serum uric acid, especially in a young patient with neurologic abnormalit...
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...
