At HFW Longevity, we use advanced health testing to uncover what may be driving fatigue, hormone imbalance, gut dysfunction, inflammation, weight resistance, poor recovery, brain fog, cellular aging, and long-term health decline.
These tests help us understand what your body actually needs before we recommend a protocol.

It’s been a blessing working with Dr. Landi and his entire team! After getting my test results, Dr. Landi walked me through a number of helpful steps to restore my health. He is very knowledgeable and uses an in-depth functional medicine approach in addressing health concerns. Bernadette is also very kind and thoughtful and I enjoy the interpersonal connection I have built with all of them.

You cannot personalize care with incomplete data.
Most standard labs are designed to look for disease-range problems. HFW testing is designed to look deeper.
We use advanced diagnostics to evaluate:
Your birthday tells one story. Your biology may tell another.
TruAge + TruHealth testing measures biological age, pace of aging, and organ-system health.
This test may help reveal how your body is aging beneath the surface across major systems like immune, metabolic, hormonal, cardiovascular, and cellular health.
What it can help assess:
Best for: Longevity planning, healthspan optimization, prevention-focused patients, and anyone who wants measurable aging data.

TruAge + TruHealth testing measures biological age, pace of aging, and organ-system health.

What it can help assess:
Best for: Longevity planning, healthspan optimization, prevention-focused patients, and anyone who wants measurable aging data.
Cellular energy starts here.
NAD+ is involved in cellular energy production, mitochondrial function, repair, and healthy aging.
This test measures your NAD+ level so your provider can better understand cellular energy status and whether NAD+ support may fit your plan.
What it can help assess:
Best for: Fatigue, low energy, poor recovery, mitochondrial support, and longevity-focused protocols.
Your gut can affect far more than digestion.
What it can help assess:
Best for: Bloating, constipation, diarrhea, reflux, IBS-like symptoms, food sensitivity patterns, fatigue, brain fog, skin issues, and inflammation.
Not just hormone levels. Hormone behavior.
DUTCH Plus is an advanced hormone test that evaluates sex hormones, hormone metabolites, cortisol rhythm, adrenal patterns, and melatonin.
Unlike a single blood draw, this test helps show how your hormones move, clear, and interact over time.
What it can help assess:
Best for: Perimenopause, menopause, PMS, low libido, fatigue, poor sleep, mood changes, anxiety, weight resistance, and hormone therapy planning.
A deeper look at cellular function and nutrient status.
Metabolomix+ evaluates nutrient status, oxidative stress, amino acids, gut metabolites, and mitochondrial markers.
This test helps identify the biochemical patterns behind energy, mood, recovery, immune function, and cellular performance.
What it can help assess:
Best for: Fatigue, brain fog, poor recovery, inflammation, nutrient depletion, chronic stress, mood changes, and mitochondrial support.
Cortisol is more than a stress hormone.
What it can help assess:
Food reactions are not always immediate.
This is not the same as an allergy test. It is used to identify delayed immune reactivity patterns that may contribute to inflammation, digestive symptoms, skin issues, fatigue, and energy crashes.
What it can help assess:
Best for: Bloating, digestive symptoms, skin flare-ups, inflammation, fatigue, food sensitivity patterns, and patients who feel worse after eating but cannot identify why.
A blood panel built around your goals.
This may include metabolic, inflammatory, hormonal, thyroid, nutrient, cardiovascular, liver, kidney, glucose, insulin, and safety markers.
Best for: Patients who need a targeted baseline, protocol monitoring, hormone safety labs, metabolic tracking, or quarterly optimization data.
A deeper bloodwork review may evaluate metabolic markers, thyroid function, inflammation, nutrient patterns, hormone markers, liver function, kidney function, cardiovascular risk, glucose regulation, and safety markers.
Best for: Baseline health review, ongoing monitoring, hormone therapy safety, metabolic health, fatigue, weight resistance, and quarterly optimization.
Galleri is a blood-based screening test designed to detect cancer signals from cell-free DNA and identify a likely tissue of origin when a signal is found.
Best for: Patients with elevated cancer risk, family history, or those seeking early-detection screening as part of a longevity-focused care plan.
The Organic Acids Test evaluates metabolic byproducts in urine that reflect energy production, nutrient processing, oxidative stress, neurotransmitter metabolism, yeast and bacterial patterns, B-vitamin status, and detox capacity.
Best for: Mitochondrial function, fatigue, brain fog, oxidative stress, nutrient strategy, detox support, and metabolic optimization.
Genetic testing helps identify inherited patterns related to nutrient processing, detox pathways, inflammation, hormone metabolism, cardiovascular tendencies, cognitive risk, and long-term health personalization.
Best for: Patients who want a more personalized nutrition, supplement, hormone, detox, and prevention strategy.
DEXA can evaluate bone density, lean muscle mass, fat mass, visceral fat distribution, and body composition trends.
Best for: Menopause, hormone optimization, GLP-1 therapy, weight loss, muscle preservation, osteopenia/osteoporosis risk, and longevity tracking.

My husband has been working for years with Dr. Landi in both chiro and functional medicine. He is so happy with the results and passionate about working with Dr. Landi I had to follow! As a women in peri-menopause I experienced issues with weight gain, low energy and aging. The peptides Dr. Landi custom recommended have been a game changer. His expertise plus amazing bedside manner and caring nature are a rare blend. I highly recommend!

I have been working with Dr Landi for several months now. He is extremely knowledgeable, attentive and responsive. He actually listens which is rare in medicine these days. I’m excited to see what the results are from my protocol in a couple of months. Highly recommend his practice if you’re looking into functional medicine.
Lauren Griffith
Dr. Landi is highly knowledgeable and skilled in the field of functional medicine, but he also possesses a genuine empathy and compassion that is so often lacking in the traditional healthcare system. Dr. Landi connects to each of his patients on a personal level, works with you every step of the way, and makes you feel supported while navigating challenging health obstacles.
Kevin Heckman
I found out about the practice of Functional Dr’e last year and realized this is what I need! Finding Dr Landi so close to home was awesome. We appreciated his candor, knowledge and engaging personality. He exuded caring and interest in me and my situation. I feel he had repeatedly gone the extra mile for me so our collaboration is successful.
