Vertebral artery dissection (VAD) is a disease of young, generally healthy individuals. Laboratory evaluation is directed toward establishing baseline parameters in anticipation of anticoagulant therapy.

Prothrombin time (PT), activated partial thromboplastin time (aPTT), and international normalized ratio (INR) are the usual monitoring parameters for patients on anticoagulant medication.

Erythrocyte sedimentation rate (ESR), if elevated, may suggest vasculitis involving the cerebrovascular circulation.
