Leptin, Serum or Plasma

This test measures the level of leptin, a hormone produced by fat cells that signals to your brain when you are full. It helps evaluate how your body regulates appetite and energy, which is particularly relevant for individuals investigating the causes of obesity or uncontrolled hunger. These results can help distinguish between rare genetic deficiencies and the more common condition where the body becomes resistant to leptin's signals. However, this test cannot identify the specific root cause of weight gain or diagnose a metabolic disorder on its own.
