Lab studies used in the diagnosis and assessment of cerebral aneurysms include the following:

  • Complete blood count (CBC) with platelets: Monitor for infection, evaluate anemia, and identify bleeding risk

  • Prothrombin time (PT)/activated partial thromboplastin time (aPTT): Identify a coagulopathy that increases bleeding risk

  • Serum chemistries, including electrolytes and osmolarity: Obtain baseline studies to monitor hyponatremia, address arrhythmogenic abnormalities, assess blood glucose, and monitor hyperosmolar therapy for elevated intracranial pressure

  • Liver function tests: Identify hepatic dysfunction that may complicate clinical course

  • Arterial blood gases: Assess blood oxygenation
