In an emergency situation like a stroke, it's important for doctors to first confirm the type of stroke to provide the appropriate treatment. Imaging tests like a CT scan or MRI can help determine the type of stroke; blood flow tests like cerebral angiography, can help evaluate the size and location of blockages.
1 These tests measure the levels of normal chemical substances in your blood. 2  The most important test in emergency stroke evaluation is glucose (or blood sugar), because levels of blood glucose which are too high or too low can cause symptoms which may be mistaken for stroke. This is a routine test to determine the number of red blood cells, white blood cells, and platelets in your blood. 2  Hematocrit and hemoglobin are measures of the number of red blood cells. 3  A complete blood count might be used to diagnose anemia (too little blood) or infection (shown by too many white blood cells).
