Question: What tests are used to diagnose diabetes? Queen (Heads of San Juan).
Answer: Diabetes can be diagnosed with a simple fasting blood test (fasting blood glucose measurement). Diabetes is diagnosed if the result is greater than or equal to 126 mg / dL twice. Levels between 100 and 126 mg / dL are called glucose intolerance or prediabetes. These levels are considered risk factors for developing type 2 diabetes and its complications.
