Urine Osmolality Test

Results and Values

What do the test results mean?

Normally, urine has an osmolality of 50 to 1,400 mOsm/kg H20 (milliosmoles per kilogram of water).

Abnormally high osmolality may be a sign of:

Addison's disease, which is caused by a deficiency of hormones produced in the adenal glands

irregularities in the secretion of antidiuretic hormone, or ADH. ADH helps the kidneys put water back into the bloodstream.

congestive heart failure, or a weakened heart that fails to pump enough blood to body cells

Abnormally low osmolality may be a sign of:

aldosteronism, a condition in which a person has too much of the hormone aldosterone, which helps the body break down and use sodium, chloride, and potassium

diabetes insipidus, a disease which causes increased thirst and urination

excessive fluid intake, which occurs when a person drinks too much fluid

kidney damage or disease

pyelonephritis, a kidney inflammation usually caused by an infection
