About Our Fasting Insulin Test
Fasting Instructions:Fasting is required for this lab test. You should not consume food or beverages other than water for at least 8 hours prior to visiting the lab. If you choose not to fast, it may affect your results.
A fasting insulin test is a valuable test used primarily to help identify insulin resistance, a condition in which the body does not use insulin effectively. This condition often precedes the development of type 2 diabetes and is a component of metabolic syndrome. Here are a few reasons why you might want to consider a fasting insulin test:
- Detect Insulin Resistance and Prediabetes: Elevated levels of fasting insulin can be an early sign of insulin resistance and prediabetes. Identifying these conditions early can enable you to make lifestyle changes or start treatments to prevent progression to type 2 diabetes.
- Monitor Treatment Efficacy: If you have been diagnosed with insulin resistance, prediabetes, or diabetes, a fasting insulin test can help monitor the effectiveness of lifestyle modifications or medications you are using to control your condition.
- Metabolic Syndrome Assessment: Metabolic syndrome is a cluster of conditions — increased blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol or triglyceride levels — that occur together, increasing your risk of heart disease, stroke, and type 2 diabetes. Insulin resistance is a key feature of metabolic syndrome, and a fasting insulin test can help evaluate this aspect.
- Polycystic Ovary Syndrome (PCOS): Women with PCOS often have insulin resistance, so a fasting insulin test can provide valuable information in the diagnosis and management of this condition.
- Hypoglycemia Evaluation: If you are experiencing symptoms of hypoglycemia (low blood sugar), a fasting insulin test, in conjunction with blood glucose testing, can help determine if you're producing too much insulin.
