Hyper/Hyponatremia:
Osmolality differentiates between real and factitious hyponatremia. Urine osmolality helps identify the genesis of hypo- and hyper-natremia.
Inappropriate ADH Syndrome: Serum and urine osmolality help determine whether SIADH is present in a patient with normal blood volume.
ADH Therapy: Urine osmolality provides a rapid measure of patient response, assisting therapy modification.
Diabetes Insipidus: Urine osmolality can measure the effects of humoral factors and offers rapid determination of the disease’s etiology.
Insulin therapy: Osmolality provides rapid assessment of the effectiveness of the insulin therapy.
