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.

No fasting required. Follow any hydration instructions from your provider — fluid intake directly affects ADH and osmolality, so don't dramatically change your water intake right before the draw unless instructed.
