Insulin Fasting Blood Test
A Insulin Fasting Blood Test is used in diagnosing and the therapy of various disorders of carbohydrate metabolism, including diabetes mellitus and hypoglycemia.
The insulin fasting blood test is chiefly used as a test insulin levels and to diagnoses diabetes and insulin resistance. The test can also hypoglycemia, an insulin related disorder.
Insulin is a peptide hormone that is produced by the pancreas and is used to control the level of glucose in in the blood. Glucose is a blood sugar that is introduced to the body by consuming carbohydrates. When glucose blood levels increase, insulin is then release from the pancreas into the blood stream. The insulin helps to remove the glucose from the blood and put it into fat and tissue cells where it can be stored for energy.
When the body is working optimally, this process of moving glucose out of the blood should only take about two hours. When glucose stays in the blood longer that this, it can cause nerve and heart damage, as well as organ and sexual dysfunction. Unfortunately, in people with diabetes, in some cases there is a lack of insulin in the body and in other cases insulin is present but is being inhibited from doing its job. The later process is known as insulin resistance. When insulin is unavailable or unable to function properly, glucose blood levels can become abnormally and dangerously high. It is also possible for insulin levels to be too high. This can result from overmedicating diabetes or from a natural occurrence of hypoglycemia, where there is so much insulin in the blood that glucose levels become dangerously low.
