A laboratory evaluation of a patient's response to administrations of desmopressin (DDAVP) is commonly performed to assess whether or not a patient can receive this product either therapeutically or prophylactically before surgery.

Perform a laboratory evaluation to rule out whether the patient has vWD type 2B prior to testing, in patients with risk factors for thrombotic complications, because case reports suggest this drug may be contraindicated in this setting.
