What is glucose serum?

Glucose is another word referring to the sugar within a person's bloodstream. According to My Lab Testing, it is the primary test done to screen for diabetes.

People get their intake of glucose from foods that are high in carbohydrates. The primary reason that people are diagnosed with diabetes is because their pancreas does not produce enough insulin to break down those sugars, according to WebMD. To complete these tests, the blood samples are spun by a centrifuge to separate the blood from the serum. This serum is a substance that is more clear in color and gives a more accurate result during the testing process.
