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 کاملEvaluation of urine specific gravity and urine sediment as risk factors for urinary tract infections in cats.
BACKGROUND It has been suggested that diseases that promote isosthenuria predispose to urinary tract infections because of a lack of the common bacteriostatic properties present in concentrated urine. OBJECTIVES The purpose of this study was to assess the clinicopathologic risk factors for positive urine culture outcome in cats with chronic kidney disease (CKD), diabetes mellitus (DM), uncont...
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 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 کاملAldosterone increases urine production and decreases apical AQP2 expression in rats with diabetes insipidus.
Vasopressin and aldosterone are essential hormones in the regulation of water and sodium balance. Aldosterone regulates sodium reabsorption, although synergistic effects on collecting duct water permeability have been shown. We investigated the effects of 7-day aldosterone infusion or oral spironolactone treatment on water balance and aquaporin (AQP) 2 expression in rats with 21 days of lithium...
