What happens during a blood glucose test? For some types of glucose blood tests, you will drink a sugary liquid and wait for an hour before your blood sample is taken: A glucose challenge test is used to test for gestational diabetes in pregnancy.

If your blood glucose level is higher than normal, you may have gestational diabetes. You'll need an oral glucose tolerance test OGTT to get a diagnosis. An oral glucose tolerance test OGTT is used to diagnose gestational diabetes, and type 2 diabetes and prediabetes in people who aren't pregnant.

A blood sample will be taken before you have a sugary drink and then again, every hour for the next 2 or 3 hours. Will I need to do anything to prepare for the test? Are there any risks to the test? What do the results mean?

High glucose levels may also be a sign of: Hyperthyroidism Pancreas disorders Stress from surgery, very serious illness, or trauma If you have diabetes, lower than normal glucose levels may be caused by: Side effects from certain diabetes medicines Not eating enough, especially after taking diabetes medicine Being more physically active than usual If you don't have diabetes, low blood glucose levels may be a sign of: Liver disease Kidney disease Underactive adrenal, pituitary , or thyroid gland hypothyroidism Alcohol use disorder AUD If your glucose results are not normal, it doesn't always mean you have a medical condition that needs treatment.

Is there anything else I should know about a blood glucose test? There are two ways to do this: Blood glucose meters require you to prick your finger with a small device called a lancet.

You apply a drop of blood to a test strip and insert it into a small, electronic glucose meter, which measures the glucose is in your blood. Continuous glucose monitors CGM use a tiny sensor that you insert under your skin. Every few minutes, the sensor measures glucose levels in fluids between your cells.

If your glucose is too high or too low, you use a blood glucose meter to check your blood levels before making changes to raise or lower your glucose level. References American Diabetes Association [Internet].

Find out your ideal target range. Not everyone with diabetes needs to check their levels like this. Everyone with diabetes is entitled to this check. High blood sugar levels increase your risk of developing serious complications.

However you manage your diabetes, stay in the know about your blood sugar levels. If you take certain medication, like insulin or sulphonylureas, checking your blood sugars is a vital part of living with diabetes. It can help you work out when you need to take more medication, when you need to eat something or for when you want to get up and move around more.

Routine checks can help you know when you might be starting to go too low called a hypo or too high called a hyper. It can help you and your healthcare team spot patterns too. Do you write your results down? You might find that helpful.

But importantly, it will help you stay healthy and prevent serious diabetes complications now and in the future. By complications, we mean serious problems in places like your feet and your eyes.

This happens because too much sugar in the blood damages your blood vessels, making it harder for blood to flow around your body. This can lead to very serious problems like sight loss and needing an amputation. Knowing all the facts and speaking to other people can help — contact our helpline or chat to others with diabetes on our online forum.

Watch our video and follow our simple steps on how to test your blood sugars in the right way and safely. New meters come on the market all the time, so it can be tricky choosing the right one.

If you have sight problems, you may not be able to use some meters so your healthcare team can suggest alternatives. Some people can get meters on prescription. But if you choose to buy your own meter, you might not get a prescription for the test strips it uses.

Chat to your healthcare team. If this happens to you, take it up with your GP practice. Walgreens sells the meter and accessories without a prescription. You may consider the Libre, G6, Guardian Connect, or Eversense based on their features, as well as the accuracy and duration of sensor wear. While most insurance and Medicare do cover CGMs, these monitors are more expensive overall.

Depending on your insurance, they may offer coverage for one type of CGM but not another. With a prescription, you may be able to buy a CGM from a medical supply store online. If you do decide to purchase a glucose meter or monitor online, be sure you know the total costs up front, including any test strips, extra sensors, lancets, and accessories that may be sold separately.

However, you do need one for a continuous glucose monitor. Some smartwatches can connect to CGM systems, allowing you to check your readings on your watch. But none are capable of taking blood glucose readings directly. These seven glucose meters offer benefits — and some drawbacks — to consider when making your ultimate selection.

You can also talk about these monitors with your doctor. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.
