NutriStat Complete


Advanced Cardiometabolic & Lipoprotein Profiling
The Complete adds full lipoprotein particle sizing, LDL phenotyping, and fasting glucose — delivering advanced cardiovascular risk data far beyond what the Basic panel provides.

Thyroid & Sex Hormone Panels Included
Rather than ordering separately, the Complete integrates thyroid and sex hormone testing into one report — directly connecting hormonal imbalances to the nutritional deficiencies already identified in the Basic.

Heavy Metal & Toxic Element Screening
The Complete adds whole blood analysis for 15 toxic elements including mercury, lead, and arsenic — giving practitioners the environmental toxin data essential for root-cause functional medicine work.

No more guessing. Get all you need for nutritional diagnostics in one test.
