What tests do functional doctors run?

Key areas include comprehensive panels for metabolism (HbA1c, insulin), thyroid (full panel with antibodies), hormones (cortisol, DHEA, sex hormones), gut (microbiome, SIBO, leaky gut), nutrient deficiencies (Vitamins D, B12, minerals), and environmental exposures (heavy metals).
