A glucose blood test measures the level of a type of sugar, called glucose in the blood. This test is used to determine if your blood sugar levels are in the healthy range. As diabetes can increase your blood glucose levels, a glucose blood test is done for people with type 1 & type 2 diabetes, and gestational diabetes. Usually, many people with diabetes need to check their blood glucose levels every day. So, if you have diabetes, make sure to talk to your health care provider about the best ways to manage your disease. Additionally, your doctor may order a glucose blood test if you have symptoms of high glucose levels (hyperglycemia) or low glucose levels (hypoglycemia).

Glucose blood test cost with insurance
Many insurance companies in the U.S. cover all the vital tests like a glucose blood test. However, the coverage provided by private health insurance companies and national health insurance programs like Medicare varies widely. Most of the health insurance policies cover glucose blood test costs only once or twice a year and when your physician orders more than twice in a year, you should pay the test cost out of pocket. So, you are recommended to check if your health insurance policy covers the glucose blood testcost.
Our glucose blood testing providers do not accept any kind of health insurance policy. However, they can provide you with an itemized receipt containing all the details viz the name of the test, code of the test, and CPT code which is necessary for insurance reimbursement purposes.
What is a glucose blood test?
Glucose, a type of simple sugar is the main source of energy for the body. The body breaks down the food we eat into glucose and other substances. And the glucose goes into the bloodstream and a hormone called insulin helps bring glucose into the body’s cells. Usually, insulin controls the amount of sugar in your blood. When a person has diabetes, their body either does not make enough insulin or the insulin produced does not work properly. And it causes sugar to build up in the blood. However, high levels of blood sugar can lead to severe organ damage if left untreated.
A glucose blood test measures the level of glucose in your blood. Too much or too little glucose may indicate a serious medical condition. This test is used to screen for diabetes (high blood sugar) or hypoglycemia (low blood sugar). And it is also used to monitor your levels when you are already diagnosed with diabetes.
A glucose blood test is also called blood sugar, self-monitoring of blood glucose, fasting plasma glucose, fasting blood sugar, or fasting blood glucose.
Purpose of glucose blood test

- To check for prediabetes and diabetes

Additionally, your doctors may also order this test when you have symptoms of high glucose levels (hyperglycemia) or low glucose levels (hypoglycemia).
Symptoms of high blood glucose levels may include:
- Increased thirst

How should you prepare a glucose blood test?
Blood glucose tests can be random or fasting tests. For this test, you should not consume food or beverages other than water eight hours before the test. You can eat or drink before a random glucose test. However, fasting tests provide more accurate results & are easier to interpret.
Make sure to tell your doctor about the medications you’re taking, including prescriptions, over-the-counter drugs, and herbal supplements before the test. Because certain medications can affect blood glucose levels. So, your doctor may ask you to stop taking a particular medication or to change the dosage before your test temporarily.
What happens during the glucose blood test?
For this test, the blood sample is most likely to be collected with a very simple prick to a finger. Or your doctor may also draw blood from a vein when you need other tests.
Before drawing blood, a nurse or healthcare professional will clean the area with an antiseptic to kill any germs. They will tie an elastic band around your upper arm, to make veins swell with blood. Once a vein is found, they will insert a sterile needle into it. And the blood is drawn into a tube attached to the needle. It is common to feel slight pain when the needle goes in. After drawing blood, your healthcare professional will remove the needle and place a bandage over the puncture site. Then the blood sample will be sent to a lab for testing.
Risk of this test
There is little risk in having a glucose blood test. You may have slight bleeding, bruising, minor pain, in the area where the needle was inserted. But the symptoms go away quickly.
What do the results mean?
For a fasting test, a normal level is between 70 and 100 milligrams per deciliter (mg/dL). Whereas for a random blood glucose test, a normal level is under 125 mg/dL. It is important to note that, the exact level will depend on when you last ate.
For a fasting blood glucose test, a blood glucose level of 100–125 mg/dL can indicate prediabetes. And when the blood glucose level is 126 mg/dL and higher it can indicate diabetes. For a random blood glucose test, the blood glucose level of 140–199 mg/dL can indicate prediabetes. And when your blood glucose level is 200 mg/dL and higher, it can indicate that you likely have diabetes. When your random blood glucose test results are abnormal, doctors may order a fasting blood glucose test to confirm the diagnosis or another test like an Hgba1c.
If the test results are not normal, it doesn’t necessarily mean you have a medical condition. Even high stress and certain medicines can also affect glucose levels. Apart from this, high glucose levels may also be a sign of kidney disease, hyperthyroidism, pancreatitis, or pancreatic cancer. And lower than normal glucose levels may be a sign of hypothyroidism, liver disease, or too much insulin or other diabetes medicine.
