Our Services

Longevity and Preventive Health Diagnostics

Every protocol at RENEWL begins with data. Six diagnostic services — from a 60+ biomarker blood panel to VO² max testing and comprehensive GI analysis — each stand alone or serve as the foundation for a complete longevity program.

Foundational Diagnostics

RENEWL Comprehensive Lab Work — 60+ biomarkers

Comprehensive Lab Work

A single, in-clinic blood draw analyzed for 60+ biomarkers — covering metabolic health, inflammation, hormones, cholesterol, blood sugar, liver and kidney function, thyroid, vitamins, minerals, and more. Results reviewed one-on-one with your physician.

Most patients have never had a full picture of what's actually happening inside their body. A single test reveals patterns that explain energy, mood, weight, sleep, and recovery struggles — and points the way toward what to actually fix.

View Detailed Analysis
What we analyze
  • Metabolic health — fasting glucose, insulin, and HbA1c
  • Cardiovascular markers — full lipid panel with advanced markers where indicated
  • Hormones — total and free testosterone, estradiol, SHBG, DHEA-S, and related markers
  • Complete thyroid assessment including free T3, free T4, and antibodies where indicated
  • Inflammation and methylation-related markers such as hs-CRP and homocysteine
  • Organ function, complete blood count, and nutrient status — vitamin D, B12, ferritin, iron
What you learn
  • A full picture of what is driving energy, mood, weight, sleep, and recovery
  • The baseline every RENEWL protocol is built and measured against
  • Patterns a minimum insurance-covered panel typically misses
  • Re-testing at 30, 60, and 90 days shows whether a protocol is working
Who it’s for

Every new patient, and anyone who has never had more than a basic annual panel.

What to expect

A single in-clinic blood draw. Results are reviewed one-on-one with your physician rather than delivered as a portal PDF.

RENEWL Methylation Test — DNA and epigenetic analysis

Methylation Test

Analyzes your body's methylation pathways — the chemical processes that switch genes on and off and influence detoxification, hormone metabolism, neurotransmitter balance, and how your cells handle stress over time.

Helps explain why two people on the same protocol can respond differently. Methylation insights inform supplement choices, nutrient targeting, and how aggressively certain pathways can be supported.

View Detailed Analysis
What we analyze
  • Methylation pathway function and related genetic variants
  • Homocysteine and functional B-vitamin status, including folate and B12
  • Markers relevant to detoxification and hormone metabolism pathways
  • Neurotransmitter-related pathway inputs
What you learn
  • Helps explain why two patients on the same protocol respond differently
  • Informs targeted nutrient and supplement selection rather than broad guessing
  • Adds context to hormone metabolism and detoxification support
Who it’s for

Patients with an incomplete response to standard protocols, a family history of methylation-related concerns, or an interest in precision nutrient targeting.

What to expect

A simple collection with physician interpretation. Genetic variants indicate tendencies, not certainties, and are read alongside your labs and symptoms.

Performance & Body Composition

RENEWL VO2 Max Testing — aerobic capacity and training zones

VO² Max Testing

A physician-supervised graded exercise test on a treadmill or bike while a metabolic cart measures the oxygen you consume and the carbon dioxide you produce — capturing maximal aerobic capacity, ventilatory thresholds, and how efficiently you burn fat versus carbohydrate.

VO² max is one of the most established measures of cardiorespiratory fitness, and research consistently associates higher fitness with better long-term health outcomes. You leave with precise heart-rate training zones and an objective baseline to re-test against.

View Detailed Analysis
What we analyze
  • Maximal oxygen uptake (VO² max, mL/kg/min) with percentile ranking against age- and sex-matched norms
  • Ventilatory thresholds (VT1 and VT2) — where effort shifts from easy aerobic work to sustained hard effort
  • Respiratory exchange ratio and substrate use — the crossover between burning fat and burning carbohydrate
  • Maximum and recovery heart rate, with training zones derived from your own data
  • Breathing efficiency, ventilation, and workload economy across the intensity range
What you learn
  • An objective cardiorespiratory baseline you can re-test to show real progress
  • Precise heart-rate zones — most people train too hard on easy days and too easy on hard days
  • The intensity where fat oxidation peaks, which may inform weight-management programming
  • A shared reference point for physician, trainer, and patient when adjusting a program
Who it’s for

Athletes and active adults, patients beginning or upgrading an exercise program, weight-management patients, and anyone focused on long-term cardiovascular and metabolic health.

What to expect

Plan for 45–60 minutes wearing a mask connected to a metabolic cart while intensity increases in stages to voluntary fatigue. Screening is completed beforehand, testing is supervised, and results are reviewed with your physician. Patients with known cardiac disease or concerning symptoms may be referred for cardiology-supervised testing.

RENEWL DEXA Body Composition Scan

DEXA Body Composition

A short, painless scan that measures exactly how much of your body is lean muscle, fat, water, and bone — with precision a regular scale cannot provide. Includes regional breakdown (arms, legs, trunk) and bone density assessment.

Knowing your true body composition changes how you train, eat, and measure progress. Patients use DEXA as a baseline and re-scan periodically to see what's actually working — not just what the scale says.

View Detailed Analysis
What we analyze
  • Total and regional lean muscle mass across arms, legs, and trunk
  • Total and regional body fat, with left-to-right symmetry comparison
  • Visceral adipose tissue — the metabolically active fat around the organs
  • Bone mineral density with standardized scoring
  • Precise tracking against prior scans
What you learn
  • Shows what the scale cannot — whether change is muscle, fat, or fluid
  • Visceral fat is more informative for metabolic risk than total weight
  • A baseline for peptide, hormone, and weight-management programs
  • Bone density adds a longevity dimension often overlooked until a fracture
Who it’s for

Weight-management and performance patients, hormone and peptide patients, and anyone wanting an objective composition baseline.

What to expect

A short, painless scan. Most patients re-scan periodically to measure change over time.

Gut & Immune Health

RENEWL GI Labs — comprehensive stool and microbiome analysis

GI Labs

A comprehensive stool analysis that maps your gut microbiome, digestive capacity, and intestinal immune markers — beneficial and opportunistic bacteria, yeast, parasites, digestion and absorption markers, and inflammatory signals. Collected with a simple at-home kit.

Bloating, irregularity, reflux, skin flare-ups, and low energy often trace back to the gut. Mapping what is actually there replaces elimination-diet guesswork with a focused plan your physician can build around.

View Detailed Analysis
What we analyze
  • Microbiome composition — beneficial and commensal species, diversity, and dysbiosis patterns
  • Opportunistic and pathogenic targets including bacteria, parasites, yeast such as Candida, and H. pylori with virulence factors
  • Digestive and absorptive capacity — pancreatic elastase, fecal fat, and bile acid markers
  • Intestinal inflammation and immune activity, including calprotectin and secretory IgA
  • Gut barrier markers such as zonulin, associated with intestinal permeability
What you learn
  • Clarifies whether symptoms track to overgrowth, insufficiency, inflammation, or barrier issues
  • Targets probiotic, antimicrobial, enzyme, and fiber strategy instead of trial and error
  • Gut status influences nutrient absorption, immune function, skin, mood, and weight regulation
  • Gives a measurable starting point that can be re-tested after a protocol
Who it’s for

Patients with bloating, gas, irregularity, reflux, or food reactions; skin issues; a history of repeated antibiotics; or unexplained fatigue — and anyone wanting a gut baseline before a longevity program.

What to expect

Collected at home with a simple kit and reviewed one-on-one with your physician. GI Labs support clinical decision-making and are not a substitute for evaluation by a gastroenterologist. Bleeding, unintended weight loss, or persistent pain warrant prompt specialty referral.

RENEWL Food Sensitivity Test — inflammatory food trigger panel

Food Sensitivity Test

A comprehensive panel identifying foods that may be triggering low-grade inflammation, digestive issues, or skin reactions. Different from a food allergy test — it identifies milder, often-overlooked sensitivities driving symptoms.

Many patients have lived with bloating, fatigue, joint pain, or brain fog without realizing food is involved. The panel turns trial-and-error elimination diets into a focused, data-driven plan.

View Detailed Analysis
What we analyze
  • A broad panel of commonly consumed foods
  • Antibody-based reactivity patterns across food groups
  • Cross-reactivity patterns among related foods
  • Results organized into a tiered reintroduction framework
What you learn
  • Turns an open-ended elimination diet into a focused, time-limited plan
  • May help explain bloating, fatigue, joint discomfort, skin changes, or brain fog
  • Pairs naturally with GI Labs when gut symptoms are the main concern
Who it’s for

Patients with suspected food-related symptoms, digestive complaints, or skin and inflammatory concerns.

What to expect

Sensitivity testing differs from allergy testing and does not diagnose food allergy. Results guide a structured elimination and reintroduction plan. Suspected true food allergy should be evaluated by an allergist.

Early Cancer Detection

Cancerguard Multi-Cancer Early Detection blood specimen kit by Exact Sciences

Cancerguard™ — Multi-Cancer Early Detection

A blood-based multi-cancer early detection (MCED) test from Exact Sciences. From a single draw, it looks for signals associated with more than 50 cancer types — including high-mortality cancers that today have no routine screening — to extend early detection beyond what standard screening covers. Physician-ordered and reviewed one-on-one.

Nearly 70% of cancer deaths come from cancers with no recommended screening. Cancerguard is designed to complement your standard screening with a single blood draw — an added early-warning layer, not a replacement for it, and not a diagnosis.

View Detailed Analysis
What we analyze
  • Multiple biomarker classes from a single blood draw, analyzed by Exact Sciences' laboratory
  • Signals associated with more than 50 cancer types and subtypes
  • Coverage of several high-mortality cancers that have no routine screening — including pancreatic, ovarian, liver, esophageal, lung, and stomach
  • A cancer-signal result and, when a signal is found, a predicted signal origin to guide next steps
What you learn
  • Whether a cancer signal is or is not detected in your blood at this point in time
  • If a signal is found, the likely origin — information your physician uses to direct follow-up
  • A designed specificity of ~97%, meaning the test is built to keep false positives low
  • Added reach beyond standard screening, which today exists for only a handful of cancers
Who it’s for

Adults roughly 50–84 with no cancer diagnosis in the past three years who want to complement — not replace — their guideline-recommended screening. Your physician determines whether it's appropriate for you.

What to expect

A simple blood draw, physician-ordered and reviewed with you. Cancerguard is a prescription laboratory-developed test from Exact Sciences; it is not FDA-cleared or approved, and it does not diagnose cancer. It is not a substitute for recommended screening such as mammography or colonoscopy. A detected signal is an early warning that requires follow-up imaging and clinical evaluation to confirm whether cancer is present; a normal result does not rule out cancer. Self-pay pricing applies and availability may vary by state.

Why Comprehensive Testing Matters

Most clinics order the minimum panel insurance will cover — leaving large gaps in the picture. At RENEWL, a comprehensive baseline reveals connections between symptoms and biology that surface-level testing misses. Knowing the data lets us recommend only what your body actually needs — and avoid what it doesn't.
