TWO INPUTS. ONE TEMPERATURE.

Your CDT is calculated from two sources.

Neither source alone gives you the full picture. Together, they reveal not just what's happening in your body, but what's driving it.

Your Health Assessment
A structured clinical intake covering sleep, stress, diet, symptoms, environmental exposures, infection history, oral health, and gut function. The upstream drivers that blood work cannot see. Research shows self-rated health alone predicts cardiovascular death at nearly 2× risk (JAHA, HR 1.92).
Your Precision Biomarkers
65+ functional medicine markers and derived ratios measured against precision reference ranges calibrated to outcomes research. Not the population averages most labs rely on. Where standard labs call an ESR under 15 normal, we flag anything above 6, because the 10-15 range is linked to 136% higher all-cause mortality.

WHAT FEEDS YOUR CDT

65+ biomarkers and derived ratios across 10 domains. Each one connected to your life.

Cardiovascular

14 markers
ApoB · Lp(a) · hsCRP · Homocysteine · Fibrinogen · HDL · LDL · Total Cholesterol · AIP · Triglycerides · RDW · ESR · Lp-PLA2 · Myeloperoxidase · NT Pro BNP
Standard cholesterol panels tell a fraction of the story. Foundation measures the particles, ratios, and inflammatory signals that actually predict cardiovascular events - and connects each to the lifestyle drivers the assessment reveals.
THE BIOMARKERS

ApoB measures the actual number of atherogenic particles in circulation, which is often more predictive of vascular risk than LDL alone.

Lp(a) is a genetically determined risk factor most clinicians never test. You cannot fully lifestyle your way out of elevated Lp(a), but it changes how aggressively other risks should be managed.

AIP (Atherogenic Index of Plasma) predicts atherosclerosis better than standard cholesterol snapshots. Foundation optimal is under 0.11; risk rises significantly above 0.24.

Homocysteine reflects methylation stress and metabolic disruption. Every 5 umol/L elevation above optimal is linked to ~40% higher heart disease and Alzheimer's risk.

HDL - Protective lipid transport, but quality and function matter as much as quantity.
LDL - A transport structure, not inherently pathological; interpreted with ApoB and inflammatory context.
Total Cholesterol - Essential substrate for hormones, vitamin D, and cell membrane function.
Triglycerides - Sugar handling signal. (Also appears in Metabolic)
hsCRP - Chronic vascular inflammation barometer. (Also appears in Inflammation & Immune)
ESR - Charge-based blood inflammation signal. (Also appears in Inflammation & Immune)
RDW - Vascular integrity marker. (Also appears in Blood Health & Clotting)
Lp-PLA2 - Arterial wall inflammation and plaque instability signal.
Myeloperoxidase - Oxidative vascular stress marker.
NT Pro BNP - Cardiac wall stress marker.
Homocysteine: Standard under 15 umol/L → Foundation 5-10
AIP: Standard usually not tested → Foundation under 0.11
LDL: Standard under 100 → Foundation 100-190
Total Cholesterol: Standard under 200 → Foundation 180-280
THE LIFE CONNECTION
Sleep debt elevates fibrinogen. Chronic stress pushes homocysteine. Processed food drives triglyceride/HDL imbalance. Oral inflammation can surface as vascular inflammation. The assessment maps these upstream drivers before care decisions are made.

Oral infectionhsCRP ↑ ESR ↑

Metabolic

7 markers
Fasting Insulin · HbA1c · Glucose · HOMA-IR · Triglycerides · Uric Acid · Homocysteine
Insulin resistance appears in these markers years before glucose goes abnormal. Most people with early metabolic dysfunction are told everything looks fine. It isn't.
THE BIOMARKERS

Fasting insulin is often the earliest metabolic warning signal. Over half of people with elevated insulin still look 'normal' on glucose and A1c.

Glucose above ~85 mg/dL can create daily endothelial irritation long before diabetes thresholds are crossed.

HbA1c reflects ~120 days of glucose exposure and helps expose silent glycemic drift.

HOMA-IR - Derived insulin resistance signal from fasting glucose + insulin.
Triglycerides - Excess carbohydrate pressure marker. (Also appears in Cardiovascular)
Uric Acid - Metabolic and oxidative stress signal. (Also appears in Kidney)
Homocysteine - Metabolic disruption marker. (Also appears in Cardiovascular)
Fasting Insulin: Standard under 25 uIU/mL → Foundation 2-6
Glucose: Standard under 99 mg/dL → Foundation 65-80
HbA1c: Standard under 5.7% → Foundation 4-5
Uric Acid: Standard 3-7 mg/dL → Foundation 4-6
THE LIFE CONNECTION
Meal timing, carbohydrate quality, sleep debt, and stress biology can produce similar lab outcomes through different pathways. The assessment identifies which mechanism is active for your pattern so intervention is specific.

Inflammation & Immune

12 markers
ESR · hsCRP · NLR · WBC · Neutrophils Absolute · Neutrophils % · Lymphocytes Absolute · Monocytes · Basophils · Eosinophils · Ferritin · Fibrinogen
Inflammation is the common thread across nearly every chronic disease. These markers reveal the type, source, and severity of immune activation that standard panels either miss or dismiss as non-specific.
THE BIOMARKERS

ESR reflects red-cell electrostatic behavior and inflammatory burden. The 'normal' 10-15 band has been linked to 136% higher all-cause mortality in apparently healthy people.

hsCRP is often dismissed as non-specific, but that broad responsiveness is exactly what makes it clinically powerful.

NLR amplifies hidden immune patterns by combining bacterial-leaning and viral/cancer-leaning directions into one prognostic signal.

WBC trend and level are deeply prognostic; chronic mild elevation is not benign.

Neutrophils Absolute - Bacterial-response load signal. (Also appears in Infection)
Neutrophils % - Differential patterning signal across immune classes.
Lymphocytes Absolute - Viral/cancer-adaptive response indicator.
Monocytes - Macrophage precursor activation signal.
Basophils - Allergy/parasitic/fungal pattern signal.
Eosinophils - Allergic/parasitic/certain malignancy pattern signal.
Ferritin - Iron/inflammation overlap marker. (Also appears in Nutrients & Minerals)
Fibrinogen - Inflammatory repair + clotting overlap. (Also appears in Cardiovascular/Blood)
ESR: Standard under 15 mm/hr → Foundation under 6
hsCRP: Standard varies → Foundation under 0.6 mg/L
NLR: Standard often not calculated → Foundation under 1.5
WBC: Standard 4,500-11,000 → Foundation 4,000-6,000
THE LIFE CONNECTION
Oral burden, gut permeability, toxin exposure, and chronic stress can all raise inflammatory signaling. Assessment context distinguishes where the immune burden is likely coming from and how urgent each pathway is.

Infection

Unique to Foundation3 dedicated + cross-referenced
Chlamydia pneumoniae Antibodies · Helicobacter pylori IgG Antibodies · Cross-referenced: Neutrophils Absolute · NLR · WBC
Chronic intracellular infection is one of four primary mechanisms driving long-horizon disease. These organisms steal cellular energy, drive inflammatory cascades, and often persist for years without obvious symptoms. Most panels don't test for them.
THE BIOMARKERS

Chlamydia pneumoniae (not the STI) is a respiratory intracellular pathogen linked in research to atherosclerosis and potentially neurodegenerative progression.

H. pylori can persist for years with minimal symptoms while driving gut barrier dysfunction, nutrient disruption, and chronic inflammatory cascades.

Foundation explicitly models chronic infection as a core mechanism in long-horizon disease risk-this is a major differentiator vs standard DTC panels.

Neutrophils Absolute - Persistent elevation can signal unresolved intracellular bacterial burden. (Also in Inflammation & Immune)
NLR - Combined immune-direction signal when bacterial and viral patterns coexist. (Also in Inflammation & Immune)
WBC - Chronic low-grade elevation can indicate unresolved biologic load. (Also in Inflammation & Immune)
THE LIFE CONNECTION
Infection history, recurrent illness, antibiotic exposure, dental history, GI symptoms, and environment all matter. The assessment helps localize likely source pathways: oral, respiratory, gastrointestinal, or environmental.

Thyroid & Hormones

10 markers
TSH · Free T3 · Free T4 · T3 · T4 · Reverse T3 · TPO Ab · Thyroglobulin Ab · DHEA-S · Cortisol
Your thyroid regulates metabolism and energy. Foundation tests the full thyroid axis including antibodies that reveal autoimmune patterns years before TSH goes out of range.
THE BIOMARKERS

TSH is a central pituitary-thyroid communication signal and often widens before overt thyroid disease is diagnosed.

TPO and Thyroglobulin antibodies expose autoimmune thyroid patterns that routine panels frequently miss.

Reverse T3 can rise under chronic stress states, functionally suppressing metabolic output despite 'normal' thyroid labs.

Free T3 - Active thyroid hormone availability.
Free T4 - Inactive thyroid hormone reservoir requiring conversion.
T3/T4 totals - Wider distribution context.
DHEA-S - Adrenal reserve and long-term stress biology marker.
Cortisol - Circadian stress axis marker. (Also in Cognitive & Stress)
TSH: Standard 0.4-6.0 mIU/L → Foundation 0.4-1.5
THE LIFE CONNECTION
Gut permeability, micronutrient sufficiency, and chronic stress tone strongly shape thyroid and adrenal outputs. Assessment data prevents one-size-fits-all endocrine recommendations.

Nutrients & Minerals

15+ markers
Vitamin D · B12 · Folate · Magnesium · Iron · Ferritin · TIBC · UIBC · TSAT · Ferritin/Iron Ratio · Calcium · Potassium · Sodium · Sodium/Potassium Ratio · Chloride · CO2 · Anion Gap
Nutrient status affects everything from energy to cognition to immune function. Standard thresholds are set for deficiency, not optimization. Foundation's ranges reflect where the research shows meaningful clinical benefit.
THE BIOMARKERS

Vitamin D functions hormonally across immune, oncologic, and metabolic systems; bone-only thresholds understate its broader role.

Ferritin is bidirectional risk intelligence: deficiency and overload are both clinically meaningful.

Iron physiology requires panel-level interpretation; single-marker review is frequently misleading.

B12 - Energy, cognition, and neurologic function marker.
Folate - Cell turnover and methylation partner to B12.
Magnesium - 300+ enzymatic process cofactor.
TIBC/UIBC/TSAT - Iron transport and saturation architecture.
Electrolytes (Ca/K/Na/Cl/CO2/Anion Gap) - Acid-base and fluid regulation context.
Vitamin D: Standard 30+ ng/mL → Foundation 55-100
Ferritin: Standard 12-150 ng/mL → Foundation 40-150
Iron: Foundation optimal 65-160 ug/dL
THE LIFE CONNECTION
Sun exposure, absorption capacity, gut integrity, alcohol intake, and food diversity patterns determine whether low or high nutrient markers reflect intake, transport, storage, or utilization issues.

Restrictive dietFolate ↓ Iron ↓

Liver

8 markers
ALT · AST · AST/ALT Ratio · GGT · Alkaline Phosphatase · Bilirubin · Albumin · LDH
Your liver is the body's detoxification and metabolic processing center. These markers catch stress, damage, and dysfunction at different stages - some early, some late.
THE BIOMARKERS

GGT is frequently an earlier liver stress signal than ALT/AST and can reflect oxidative and toxic burden.

Alkaline phosphatase provides hepatobiliary patterning that helps separate liver, bile, and bone-linked processes.

ALT - Hepatocellular injury marker.
AST - Hepatic + tissue stress marker.
AST/ALT ratio - Pattern-discrimination signal.
Bilirubin - Clearance and hemolysis context.
Albumin - Hepatic synthetic function marker.
LDH - Tissue stress and turnover marker.
AST: Standard 10-40 IU/L → Foundation 10-26
ALP: Foundation optimal 45-110
Bilirubin: Foundation optimal 0.1-0.9
THE LIFE CONNECTION
Medication load, alcohol, hydration, environmental burden, and nutrition patterns can create distinct liver signatures that look identical without intake context.
ASSESSMENT → BIOMARKER CONNECTIONS
Alcohol consumptionGGT ↑ AST ↑
Medication loadALT ↑ ALP ↑
Environmental toxinsGGT ↑ Bilirubin ↑
Poor hydrationBUN ↑ Albumin shifts

Kidney

6 markers
eGFR · Creatinine · BUN · BUN/Creatinine Ratio · Uric Acid · Albumin/Globulin Ratio
Kidneys have substantial reserve capacity, which means standard markers don't flag problems until significant function is already lost. Foundation's thresholds catch decline earlier.
THE BIOMARKERS

eGFR catches decline earlier than creatinine because kidneys have substantial reserve capacity.

BUN/Creatinine ratio offers strong hemodynamic and catabolic context often missed in single-marker review.

Creatinine - Filtration stress marker that rises late.
BUN - Protein catabolism and clearance signal.
Uric Acid - Oxidative/metabolic and renal overlap marker. (Also in Metabolic)
Albumin/Globulin ratio - Liver-kidney-immune pattern marker.
eGFR: Foundation optimal 90-120 mL/min
BUN/Creatinine ratio: Foundation optimal 10-21
THE LIFE CONNECTION
Hydration behavior, blood pressure history, protein intake, and medication use shift kidney interpretation dramatically. Assessment context prevents overcalling benign shifts or missing true decline.

Blood Health & Clotting

12 markers
CBC · Hemoglobin · Hematocrit · MCV · MCH · MCHC · RDW · Platelets · Fibrinogen · D-dimer · INR · Prothrombin Time
Your blood is a transport system, and its composition reveals your body's state. These markers map oxygen delivery, clotting function, and vascular inflammation.
THE BIOMARKERS

RDW is among the strongest vascular risk correlates and can surface endothelial stress long before overt disease events.

Hemoglobin reflects oxygen delivery capacity and iron biology simultaneously; both low and high states carry risk.

CBC - Complete blood architecture snapshot.
Hematocrit - Cell volume percentage context.
MCV/MCH/MCHC - Red cell structure and hemoglobinization patterning.
Platelets - Clotting volume + thrombotic tendency signal.
Fibrinogen - Repair/clot overlap marker. (Also in Cardiovascular/Inflammation)
D-dimer - Active clot turnover signal.
INR/PT - Clotting speed and coagulation pathway timing.
RDW: Foundation optimal 11-12.5%
Hemoglobin: Foundation optimal 12.0-15.5 g/dL
Platelets: Foundation optimal 150-379 x1000/uL
THE LIFE CONNECTION
Menstrual history, recent illness, hydration, iron intake/absorption, altitude, and medication profile all shift blood and clotting interpretation. Assessment data turns abnormal values into a root-cause map.

Cognitive & Stress

4 markers
Cortisol AM · BDNF · Omega-3 Index · CoQ10
These markers map your brain's health trajectory and your body's capacity to handle chronic stress. Chronic dysregulation here cascades into sleep, immunity, metabolism, and cognition.
THE BIOMARKERS

Cortisol AM anchors circadian stress axis function; chronic dysregulation cascades into sleep, glucose, immunity, and cognition.

BDNF is a central neuroplasticity and neuroprotection signal linked to learning and cognitive resilience.

Omega-3 Index - Membrane-level neurocardiovascular resilience marker.
CoQ10 - Mitochondrial energy support marker, often relevant with age and statin use.
Cortisol cross-reference - Also in Thyroid & Hormones.
THE LIFE CONNECTION
Sleep architecture, perceived stress load, movement pattern, and dietary fat quality all influence these markers in different directions. Assessment context determines which behavior changes will move the needle fastest.
