Insert a test strip into the meter. Puncture the side of the fingertip with the needle (lancet) that comes with the test kit. Touch and hold the edge of the test strip against the drop of blood. The meter will show your blood sugar level on a screen after a few seconds.
A person cannot diagnose diabetes with home tests alone. People with unusual readings will need more tests by a doctor. You may also need to contact your doctor for preventive tests, such as cholesterol checks and eye exams. Home blood glucose testing is a safe and affordable way for people to detect diabetes before it causes problems.
