Migraine FAQs: Is blood testing conducted to diagnose migraine?

As with all tests given to migraine sufferers, blood chemistry tests are conducted only to rule out other causes of the migraine symptoms.

These tests do not confirm a migraine diagnosis.

Blood chemistry tests can detect anemia, infections, blood clots or clotting problems, immune system disorders, arthritis, HIV and other sexually transmitted diseases, and diabetes (or other blood sugar issues)
