For headache associated with head trauma or a significant intracranial hemorrhage, the following laboratory studies may be indicated:

  • Complete blood count

  • Prothrombin time

  • Activated partial thromboplastin time

Lumbar puncture may reveal elevated opening pressure, leukocytosis, elevated protein, and low glucose. It is the most sensitive test in the diagnosis of subarachnoid hemorrhage.
