Laboratory studies to be considered in the workup of carotid atherosclerosis include the following:

  • Complete blood count (CBC)
  • Electrolytes, blood urea nitrogen (BUN), and creatinine
  • Lipid profile
  • Prothrombin time (PT) and activated partial thromboplastin time (aPTT) - Heparin is administered during carotid endarterectomy (CEA), and knowing the PT or aPTT preoperatively is important
