Diabetes is typically diagnosed through a series of blood tests that measure blood sugar levels. The most common tests include the fasting plasma glucose test, which measures blood sugar after not eating for at least 8 hours, and the A1C test, which provides an average of blood sugar levels over the past 2-3 months. Other tests like the oral glucose tolerance test may also be used. If blood sugar levels are above normal ranges, further testing and monitoring may be recommended to confirm a diabetes diagnosis. Early diagnosis is crucial for proper management and preventing complications. [https://www.niddk.nih.gov/health-information/diabetes/overview/tests-diagnosis]
