Can a store-bought blood glucose meter diagnose diabetes?

No. Diagnosis comes from blood tests by a health care professional.

  1. Yes, one high reading is enough
  2. Yes, if you test twice in a day
  3. No, it takes office or lab tests ✔

Why: Home meters are great for managing diabetes, but they can't diagnose it. If you think you might have diabetes, get tested by a health care professional instead of guessing.

Huh, didn't know that: NIDDK says anyone who has symptoms of diabetes should be tested for it.
