The primary goals of the workup are to (1) establish the type of vascular lesion and the mechanism of the stroke and, if early enough, (2) establish whether acute intervention is needed to achieve recanalization.

The laboratory workup should include the following:

  • Complete blood count (CBC)

  • Electrolyte values

  • Blood urea nitrogen (BUN) and creatinine determination

  • International normalized ratio (INR)

  • Prothrombin time (PT) and activated partial thromboplastin time (aPTT)

  • Lipid profile
