MedlinePlus Medical Encyclopedia: Blood glucose monitoring (542 words) |
 | Blood glucose monitoring is a measurement of glucose (sugar) in the blood. |
| The finger is pricked and a drop of blood is put on a special strip, which uses a chemical substance to determine the amount of glucose in the blood. |
| The test allows the person with diabetes to carefully monitor blood glucose levels, to assure that they are within the normal range. |
| Glucose Tests: The Test (0 words) |
| Blood glucose testing can be used to screen healthy, asymptomatic individuals for diabetes and pre-diabetes because diabetes is a common disease that begins with few symptoms. |
| Blood glucose testing is also done in emergency settings to determine if low or high glucose is contributing to symptoms such as fainting and unconsciousness. |
| Hypoglycemia is characterized by a drop in blood glucose to a level where first it causes nervous system symptoms (sweating, palpitations, hunger, trembling, and anxiety), then begins to affect the brain (causing confusion, hallucinations, blurred vision, and sometimes even coma and death). |
