The best way to monitor blood sugar levels is by testing blood from a finger prick with a glucose meter, according to WebMD. Those with diabetes need to test their blood sugar levels before meals, exercise, driving and going to bed. Testing several times a day is best.
In some patients, continuous glucose monitoring systems monitor blood sugar levels instead of more traditional glucose meters, states WebMD. Patients with insulin pumps use these systems to provide a regular stream of data to keep their insulin levels close to normal. The system stores the data for analysis through a computer program or by a doctor at a later time.
The A1C is another test that helps properly monitor blood sugar levels, maintains the Joslin Diabetes Center. The A1C test requires a finger-prick blood sample and is typically administered by a nurse or physician at regular diabetes care appointments. The test gives a picture of what the patient's average blood sugar level was for the last three months. It is not a substitute for regular at home monitoring with a glucose meter.
The best home glucose monitors are those that patients find easy to use and easy to carry with them, according to the Joslin Diabetes Center. It recommends carrying a small meter and other testing supplies along on outings to make it easy to monitor blood sugar levels on the go.
