Measures antidiuretic hormone (ADH) with serum osmolality — evaluates water balance disorders, unexplained sodium abnormalities, and diabetes insipidus. The Antidiuretic Hormone (ADH) Profile measures vasopressin — the hormone that regulates how your kidneys retain water — alongside serum osmolality, which shows the concentration of your blood at the time of the draw. Interpreting the two together is what makes this profile clinically useful: ADH should rise and fall in lockstep with osmolality, and a mismatch points toward conditions like diabetes insipidus (too little ADH effect), SIADH (too much), or primary polydipsia. It's typically ordered when evaluating persistent sodium abnormalities, excessive thirst and urination, or unexplained fluid retention. Because ADH is measured directly, this is a specialty send-out test — results take a few days longer than routine labs. **Clinical use:** Hormone testing measures the chemical messengers that regulate energy, mood, sex drive, weight, and reproduction — helping pinpoint imbalances that cause a wide range of symptoms. ## Who should order it? Anyone with unexplained fatigue, mood changes, libido changes, weight changes, irregular cycles, or considering hormone replacement therapy. ## Biomarkers measured - ADH (Antidiuretic Hormone) - Osmolality ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Labcorp | $109.99 | $115.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | Rhode Island is not served.
