Glucose Blood Test - More Information
The blood glucose test is a core test in screening for diabetes and checks the level of glucose, or sugar, in the blood. Sometimes known as a fasting blood sugar (FBS) test because it is usually performed after an 8-hour fast, this test is frequently used by diabetics to manage their medications and by people in general who want a basic screen for diabetes.
Technological innovations over time have made the blood glucose test more accessible by allowing people to check their blood glucose levels using a home device called a glucose meter and a drop of blood from one's finger. However, some people prefer to get their glucose test done at a lab to avoid user error or because they want to test other markers such as their hemoglobin A1c level concurrently (all part of the diabetes screening panel).
While the glucose blood test is a useful screening tool, it does represent one's glucose level at only one point in time. As a result, the glucose test result cannot tell if one's glucose is spiking throughout the day but happened to be normal at the time of testing. Fortunately, other lab markers can help clarify what is happening to the blood sugar level at other times. The hemoglobin A1c and fructosamine tests can give one a better picture of the average blood sugar over different periods of time. For even more data, the newer GlycoMark test was designed specifically to help assess glycemic variability and the tightness of blood sugar control over time.
The glucose test also plays a role in other tests. For example, the blood glucose level is measured as part of the glucose tolerance test during which an oral solution is administered and blood glucose levels are measured to understand how quickly the body can clear glucose out of the bloodstream.
