An Overview of Stroke Tests
If a healthcare provider believes that a person is having a
stroke, there are a number of tests that he or she may recommend. Some of these tests help determine whether possible
stroke symptoms are actually being caused by a stroke or by another medical condition. Once a doctor has diagnosed a stroke, he or she may recommend other stroke tests to identify the cause of a stroke. In addition, doctors use some stroke screening tests to look for problems before a stroke happens. Finally, a number of these tests may be used for multiple purposes, such as for screening for
stroke risk factors or determining the cause once a stroke has occurred.
We will discuss these different stroke tests, including:
- Blood tests
- Common imaging tests used to diagnose a stroke
- Other tests doctors may recommend for screening, diagnosis, or for determining the cause of the stroke.
Blood Tests for Stroke
Healthcare providers may use blood tests to look for stroke risk factors along with certain conditions that may mimic stroke symptoms. Blood tests for stroke may include:
- A blood glucose test that checks your blood sugar level. Diabetes is a risk factor for stroke. Also, both low blood sugar (hypoglycemia) and high blood sugar (hyperglycemia) can mimic the symptoms of a stroke.
- A complete blood count (CBC) to look for certain causes of stroke, such as low platelets, anemia (including sickle cell anemia), or high white blood cells (from leukemia).
- Erythrocyte sedimentation rate (sed rate) to check for inflammation. There are several conditions that cause inflammation of blood vessels that can lead to a stroke. One example is temporal arteritis (also known as giant cell arteritis).
