Every adult should have their fasting Insulin level checked.

If your doc doesn't know what that is, tell her/him it's CPT code 83525...

If your doc asks why you want it, say

"A fasting insulin test is crucial for assessing insulin resistance, a precursor to type 2 diabetes and metabolic syndrome. It provides early insight into metabolic health, often before glucose levels are affected, enabling proactive interventions to prevent chronic diseases and improve long-term health outcomes."
