Diabetes is typically diagnosed through various methods. Common diagnostic tests include a fasting plasma glucose (FPG) test, an oral glucose tolerance test (OGTT), and a glycated hemoglobin (A1C) test. These tests measure blood glucose levels and provide insights into a person’s diabetes status. Healthcare professionals evaluate the results alongside clinical symptoms and medical history to make an accurate diagnosis and determine the appropriate treatment plan. Regular screenings are recommended for individuals at high risk of developing diabetes.
