Leptin
Also known as Leptin
What it is
Leptin is a hormone produced by fat cells that signals satiety and metabolic reserve to the brain.
Why it matters
Leptin gives insight into fat mass signaling and appetite regulation, especially in patients with weight resistance despite lifestyle change.
Range GPLX watches for
GPLX watches for leptin within age- and sex-appropriate reference ranges. Very high leptin often accompanies obesity and leptin resistance.
This educational range is not a personal diagnostic threshold. Your physician interprets your result in context of your full biomarker panel, medications, symptoms, and history.
What abnormal values can suggest
If low
A low leptin value can suggest low body fat, prolonged caloric restriction, or, rarely, leptin deficiency.
If high
A high leptin value can suggest obesity, leptin resistance, or inflammation.
