Insulin is a hormone that is produced and stored in the pancreas.
Insulin helps transport glucose, the body’s main source of energy, from the blood to within cells. It also helps regulate blood glucose levels and has a role in lipid metabolism.
This test measures the amount of insulin in the blood. Insulin levels are most frequently ordered when someone has acute or chronic symptoms of low blood glucose (hypoglycemia) levels.
An insulin test may also be done when an individual has or is suspected of having insulin resistance. This may include people with type 2 diabetes, polycystic ovarian syndrome (PCOS), prediabetes or heart disease, or metabolic syndrome.
Requirements: Fasting required (Please consult your physician). To fast for blood work, do not eat anything for 8 to 12 hours before the test. It’s best to schedule fasting blood work for the morning, so that you don’t have to spend the whole day hungry. If fasting is not done before blood work, the results of the blood tests may be inaccurate.
