Functional Health Genetic Test
One cheek swab. 767 genetic insights across 10 reports and six areas of whole-body health.
Genetic Tests are a one-time purchase
The Functional Health Genetic Test analyzes your DNA to deliver 760+ genetic insights across 10 reports, covering methylation and detox, nutrition, weight, fitness, hormones, and longevity and heart health.
What your DNA reveals in this test
Methylation, detox & cellular processing
How your genes may shape methylation, the transsulfuration pathway, and the two phases of detox your body uses to process everyday compounds. The well-known MTHFR gene sits here.
Nutrition, vitamins & food response
How well your body absorbs vitamins and minerals, responds to different foods and diet types, and handles histamine and common food triggers.
Weight, appetite & metabolic response
How your genes may shape hunger, fullness, fat storage, blood sugar handling, and the way your body responds to losing weight and keeping it off.
Fitness, performance & recovery
How your genes may shape endurance versus power, mitochondrial energy, training response, and how your body recovers from exercise.
Hormones, thyroid & fertility
How your genes may shape estrogen, progesterone, and testosterone balance, thyroid hormone activity, and fertility-related pathways, for context to review with your provider.
Longevity, heart & healthy aging
How your genes may shape cellular aging and telomere maintenance, inflammation, heart and cardiovascular balance, and joint, bone, and skin resilience. Context, not a diagnosis.
What this test covers
This test analyzes your DNA across all 10 PlexusDx genetic reports: 767 markers across 176 traits, grouped into the six areas below.
Methylation, detox & cellular processing
How your genes may shape methylation, the transsulfuration pathway, and the two phases of detox your body uses to process everyday compounds. The well-known MTHFR gene sits here for folate handling, alongside COMT and CBS for methylation and GSTP1 for conjugation.
Nutrition, vitamins & food response
How well your body absorbs and uses vitamins and minerals, how you respond to different foods and diet types, and how you handle histamine and common food triggers. This area includes VDR for vitamin D, HFE for iron, and AOC1 for histamine breakdown.
Weight, appetite & metabolic response
How your genes may shape hunger, fullness, fat storage, blood sugar handling, and the way your body responds to losing weight and keeping it off. This area includes the well-known FTO gene, MC4R for appetite, and TCF7L2 for blood sugar response.
Fitness, performance & recovery
How your genes may shape endurance versus power, mitochondrial energy production, training response, and how your body recovers from exercise. This area includes the well-studied ACTN3 power gene, PPARGC1A for mitochondrial energy, and COL5A1 for tendon resilience.
Hormones, thyroid & fertility
How your genes may shape estrogen, progesterone, and testosterone balance, thyroid hormone activity, and fertility-related pathways. This area includes SHBG for free testosterone, CYP19A1 for estrogen production, and DIO2 for the T4-to-T3 conversion behind your metabolic pace.
Longevity, heart & healthy aging
How your genes may shape cellular aging, telomere maintenance, inflammation, and heart and cardiovascular balance, along with joint, bone, and skin resilience as you age. This area includes FOXO3 and SIRT1 for cellular aging, TERT for telomere maintenance, and APOB and PCSK9 for cholesterol handling.
You do not have to act on all of it. Pick one or two areas, talk them over with your doctor, and build from there. This test shows genetic tendencies, not a diagnosis. It does not diagnose, treat, or predict any condition, and it does not guarantee any specific outcome.
