Urine Electrolytes Interpretation. Urinary potassium in the diagnosis of hypokalemia for the evaluation of urinary acidification problems eg. Pitfalls in this assessment are abnormal renal and adrenal function and the use of diuretics. Also urine osmolality is helpful in the differential diagnosis of hyponatremia polyuria and aki. When used with serum values urinary diagnostic indices can be generated.
Used in the diagnosis of a number of electrolyte disturbances in icu especially when intake of electrolytes is known and relatively controlled uses. The determination of urine electrolyte and creatinine concentrations may be helpful in the differential diagnosis of arf. The present brief review discusses the various aspects of the correct interpretation of urinary electrolytes solute excretion and urine flow in the setting of a rising serum creatinine. Una low 10 extra renal losses. Also urine osmolality is helpful in the differential diagnosis of hyponatremia polyuria and aki. They ensure that this balance does not fluctuate greatly from the needed level.
A urine potassium to creatinine ratio corrects for variations in urine volume.
However it is measured by determining the urine concentrations of na k and cl and is calculated as na k cl. If the ratio is less than 13 meq g hypokalemia is likely due to transcellular potassium shifts gi losses diuretics or poor intake. Urinary potassium in the diagnosis of hypokalemia for the evaluation of urinary acidification problems eg. To detect a mild to moderate degree of reduction of the effective intravascular volume both urine sodium na and chloride cl concentrations should be measured. The present brief review discusses the various aspects of the correct interpretation of urinary electrolytes solute excretion and urine flow in the setting of a rising serum creatinine. However it is measured by determining the urine concentrations of na k and cl and is calculated as na k cl.
