It is usually done in the morning after you have been fasting (not eating) for at least eight to 12 hours. Depending on your age, family history, medical conditions, and risk factors, your doctor will decide how often you should have a fasting blood sugar test.\u00a0<\/span><\/p>\n<h3 id=\"how-to-prepare\"><span style=\"font-weight: 400;\">How to prepare<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">There is not much to do to prepare for a fasting blood sugar test in the lab. All you have to do is go to the lab with your blood test orders. It\u2019s best to go in the morning after you have not had anything to eat or drink (except water) for at least eight to 12 hours. The phlebotomist will take a blood sample, and depending on the lab, you should have results in anywhere from 24 to 72 hours. Having a fasting blood sugar test is just like any other blood work\u2014in fact, it\u2019s often done in combination with other blood work that your doctor orders.\u00a0<\/span><\/p>\n<h3 id=\"can-i-do-a-fasting-blood-sugar-test-at-home\"><span style=\"font-weight: 400;\">Can I do a fasting blood sugar test at home?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">If you want to do a fasting blood glucose test at home, you can use a blood glucose meter to perform the test yourself. You may need to watch the training videos if you have not used a meter before. You can use the blood glucose meter to check your fasting blood sugar. If you are interested in a more complete picture of your blood sugar, you can ask your healthcare professional if continuous glucose monitoring is an option for you. Continuous glucose monitors (CGMs) use a sensor to capture blood sugar data frequently throughout the course of a day\u2014every one to five minutes, depending on the particular CGM. Using a CGM, you would be able to see your fasting blood sugar every day, as well as throughout the day and night.\u00a0<\/span><\/p>\n<h3 id=\"other-tests-to-diagnose-diabetes\"><span style=\"font-weight: 400;\">Other tests to diagnose diabetes<\/span><\/h3>\n<p><b>Hemoglobin A1C<\/b><span style=\"font-weight: 400;\">: Your doctor may also order a test called <\/span><a href=\"https:\/\/www.singlecare.com\/blog\/normal-a1c-levels\/\"><span style=\"font-weight: 400;\">hemoglobin A1C<\/span><\/a><span style=\"font-weight: 400;\">.

If blood sugar stays low for too long, it may lead to seizures or coma (and very rarely can cause death). If you are at high risk for having low blood sugar levels, it is important to carry a source of fast-acting carbohydrates with you at all times, such as glucose tablets or Smarties, to treat low blood sugar quickly. Your doctor may also prescribe Baqsimi, which is a nasal spray that contains glucagon.
