Serum or plasma mass concentration of desmopressin (DDAVP)

What Is Desmopressin Used For?

Desmopressin (DDAVP) is a hormone that mimics the effects of naturally occurring antidiuretic hormone (ADH). It is used primarily in medical settings to manage conditions like von Willebrand disease (a bleeding disorder), central diabetes insipidus (extreme thirst and frequent urination), and hemophilia A (a clotting disorder). It may also be used in other rare conditions where blood clotting or fluid balance needs support.

How Is This Test Performed?

A blood sample is drawn from a vein, usually in your arm. The sample is then processed to measure the concentration of desmopressin in the serum or plasma. The test result indicates how much of the hormone is present in your bloodstream.

What Does the Test Result Mean?

The test result provides a quantitative measure of desmopressin levels. This information helps healthcare providers assess whether your body is producing or responding appropriately to the hormone, especially if you are taking desmopressin as treatment.

Common Conditions Monitored With This Test

This test is often used in patients who are receiving desmopressin therapy to monitor its effectiveness. It may also be used in research or specialized clinical scenarios to study hormone levels in conditions affecting fluid balance or clotting.
