Insulin−Fasting Test

What is an Insulin Fasting Test?

• Purpose: The Insulin Fasting Test measures the level of insulin in the blood after an overnight fast (typically 8 to 12 hours without food or drink except water).
• Insulin: Insulin is a hormone produced by the pancreas that helps regulate blood sugar (glucose) levels. It facilitates the uptake of glucose into cells for energy or storage.

Why is the Insulin Fasting Test Important?

1. Diagnosis of Diabetes: Helps diagnose Type 1 or Type 2 diabetes by assessing how well the body regulates blood sugar levels.
2. Insulin Resistance: Used to diagnose insulin resistance, a condition where cells do not respond properly to insulin.
3. Monitoring Treatment: Assesses the effectiveness of treatment in individuals with diabetes or insulin resistance.

When Should You Get an Insulin Fasting Test?

• Diabetes Symptoms: If you experience symptoms such as frequent urination, excessive thirst, unexplained weight loss, or fatigue.
• Risk Factors: Individuals with risk factors for diabetes, such as obesity, family history of diabetes, or sedentary lifestyle.
• Polycystic Ovary Syndrome (PCOS): Used in the evaluation of women with PCOS who are at higher risk of insulin resistance.
• Monitoring: Individuals with diabetes may have regular insulin tests to monitor their condition and adjust treatment as needed.
