Blood Sugar Testing At Home

What Is The Best Time To Check Your Blood Sugar.

A person can test their blood sugar levels at home.

In most cases, doctors ask people to measure fasting blood sugar immediately upon waking and before they have anything to eat or drink. It may also be appropriate to test blood sugar before eating or 2 hours after a meal, which is when blood sugar returns to normal levels.

The right time to test depends on treatment goals and other factors. For example, most people with diabetes do not need to test between meals unless they are using a diabetes drug that can lower blood sugar. Other people may test between meals if they feel their sugar levels may be low.

Since people with type 1 diabetes do not make any insulin, they need to test their blood sugar levels several times a day so they can adjust their insulin doses.


A person will test blood sugar levels by:

  • preparing the testing strip and glucose monitor to be ready for the blood sample
  • using an alcohol swab to clean the testing area, which is usually the side of a fingertip
  • lancing the testing area and bracing against a firm surface to help resist the impulse to pull away
  • squeezing the testing area around the wound to maximize blood flow
  • squeezing a drop of blood onto the test strip
  • putting the strip into the monitor
  • recording the time, blood sugar reading, and recent food intake in a log

However, the advice a person receives on when to monitor and what the results should be generally depend on his type of diabetes, age and state of overall health. It can also depend on a health-care providers philosophy of care and which set of diabetes care guidelines he follows. At least three major health organizations have published slightly different recommendations regarding goals for blood sugar levels.

There is some common ground when it comes to blood sugar monitoring practices. For example, most people take a fasting reading before breakfast every morning. Some people also monitor before lunch, dinner and bedtime some monitor after each meal and some monitor both before and after all meals. However, when monitoring after meals, some people do it two hours after the first bite of the meal, while others prefer to check one hour after the start of a meal.
