You may test your blood sugar regularly – 4 or more times per day. It is common to test blood sugar levels before meals and snack time at night. You can also test before lunch at school if you feel comfortable with that. It’s best to discuss what is best for you with your parents and doctor.
How blood checks work
A tiny needle (called a lancet) is used to stick your finger to draw a drop of blood. You can also draw blood from your forearm, thigh or fleshy part of your hand with some glucose meters. Some lancing devices are spring-loaded – this will make sticking yourself less painful. Before starting the test, wash your hands or sticking site with soap and water. If you use your fingertip, stick the side of fingertip with the lancet. This helps to pool blood and avoid sore spots on this part of finger.
Checking with a blood glucose meter
You can check your blood sugar level by using blood glucose meters. They are small computerized machines that will show your blood sugar level by displaying numbers on the screen. Your doctor will show you how to use your meter correctly. It is better to use a meter than visual checking.
Logging your results
Once you finish the blood sugar test, write down the result. You can use these results to see how food, activity and stress affect your blood sugar. Compare your results with the previous days’ records to see if your blood sugar level is rising or dropping. If the result continues to be too high or low, your plan may need to be adjusted. You can learn what your results mean by working with your doctor.
