What is the purpose of this test?
The Insulin Fasting Blood Test measures the amount of insulin in your blood after you haven't eaten for a certain period, usually about 8 to 12 hours. Insulin is a hormone that helps control your blood sugar levels. By checking your fasting insulin levels, doctors can see how well your body is managing blood sugar, which is important for diagnosing and monitoring conditions like diabetes and insulin resistance.
This test helps doctors understand if your body is producing the right amount of insulin. High insulin levels can indicate that your body is having trouble using insulin properly, which can lead to insulin resistance. On the other hand, low levels might suggest issues with insulin production. The results of this test can help doctors develop a treatment plan to manage your blood sugar levels and prevent complications related to diabetes and other metabolic disorders.
