What happens during a blood glucose test?A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. For some types of glucose blood tests, you will need to drink a sugary drink before your blood is drawn.If you have diabetes, your health care provider may recommend a kit to monitor your blood sugar at home. Most kits include a device to prick your finger (lancet). You will use this to collect a drop of blood for testing. There are some newer kits available that don’t require pricking your finger. For more information on at-home test kits, talk to your health care provider.
