Urine osmolality and creatinine are highly correlated (Yeh et al.
Urine electrolyte analysis revealed a urine osmolality of 215 mOsol/kg, urine sodium of 81 meq/L, urine creatinine of 14 mg/dl, serum sodium of 137 meq/l, and serum osmolality of 278 mOmsol/kg.
Measured serum osmolality was 270 mOsm/kg/L (285-295 mOsm/kg/L), urine osmolality 320 mOsm/Kg/L.
A man's man, characterised by honesty, integrity, humility, diligence and a love of exuberant laughter; highly adventurous and of great courage, racing the death-defying Isle of Man motorcycle event; walking across the Sahara with a Taureg, recording urine osmolality along the trip; and being a military medical officer with the UN in the (then) Belgian Congo.
2 HCO3 (mmol/L) 32 33 Chloride (mmol/L) 93 95 Serum osmolality (mOsm/kg) -- 286 Urine osmolality (mOsm/kg) -- 379 Spot urine chloride (mmol/L) -- 239 Spot urine sodium (mmol/L) -- 178 Spot urine creatinine (umol/L) -- 3978 Spot urine potassium (mmol/L) -- 106 pH -- 7.
Urine osmolality is suggested to be the most accurate indicator of total solute concentration, which is influenced by hydration.
Serum osmolality was 236 mOsm/kg, urine osmolality was 402 mOsm/kg, and the urinary sodium concentration was 109 mmol/L.
With in vivo studies, Oliver et al (1982) reported that most of the increase in urine osmolality above isotonicity occurs in the terminal 25% (last 2 mm) of the rat medullary collecting duct.
The biochemical work-up included: in urine: creatinine concentration and urine osmolality, UA excretion expressed as 1.
Serum osmolality was mildly increased (patient value: 287 m osm/kg, normal: 270-285 m osm/kg), urine osmolality was normal (patient value: 177 m osm/kg, normal: 50-1400 m osm/kg) and urinary sodium was normal (patient value 32 mmol/L).
