At The KEY, diagnostics aren’t a check-up — they’re a blueprint. We combine advanced blood panels with AI-driven analysis to uncover root causes, optimize biology, and track progress with scientific precision. Our protocols go beyond traditional testing, offering a comprehensive understanding of your body’s performance, resilience, and risk factors.

The KEY Diagnostics

Root-Cause Testing, Precision Planning

What We Test

1. Blood & Biomarker Panels

In-depth analysis of vitamins, minerals, hormones, lipids, metabolic function, immune status, and inflammation markers. These include:

  • Complete Blood Count

  • Omega-3/Omega-6 ratios

  • Homocysteine

  • CRP / IL-6 / TNF-α

  • Mitochondrial markers

Stool diagnostics provide a comprehensive picture of gut health by assessing microbiota diversity, digestive enzyme activity, intestinal inflammation, and the presence of pathogens or leaky gut. These insights are foundational for immune function, mood regulation, and overall metabolic balance.

2. Gut Health & Microbiome

3. Neurotransmitters & Mental Health Markers

Urinary and blood profiles that map mood-regulating neurotransmitters (serotonin, dopamine, GABA), plus tryptophan metabolism and kynurenine pathway activity.

Thyroid, adrenal, and sex hormone testing to assess endocrine balance and bioavailable hormone levels — key to longevity, energy, and cognitive health.

4. Hormonal Mapping

Functional markers for energy production, mitochondrial stress, oxidative damage, and cellular efficiency — including NAD status, Q10 levels, and fatty acid oxidation.

5. Metabolic & Mitochondrial Testing

6. Heavy Metals & Detox Pathways

Urine and blood testing for toxins like mercury, lead, and arsenic. Plus genetic and enzymatic markers for detox efficiency (e.g., COMT, MTHFR).

7. Epigenetic & Genetic Testing

Insights into biological age, longevity predispositions, and SNPs (single nucleotide polymorphisms) affecting nutrient absorption, metabolism, and disease risk.

Optional Add-On Programs

  • Methylation Profile

  • Nitrostress Analysis

  • Histamine & DAO Activity

  • Amino Acid Profile

  • Tryptophan–Kynurenine Pathway Mapping

Designed for Personalization

These diagnostics aren’t just data points — they guide your personalized protocol. Whether it’s for anti-aging, gut restoration, cognitive enhancement, or immune optimization, every treatment begins with clarity.
