Answer

Lab studies may include the following:

  • CBC count with differential

  • Electrolyte panel

When a patient initially presents with transient global amnesia, stroke must be ruled out. This can be done using screening clotting tests, including prothrombin time (PT), activated partial throboplastin time (aPTT), and INR.
