Longevity Labs — the tests your last doctor didn't run.
Our Longevity Labs panel goes well beyond a standard annual physical. These are the functional and longevity markers that reveal metabolic dysfunction, hormonal imbalance, nutrient depletion, and systemic inflammation — often years before conventional testing catches it.

Complete Blood Count
7 markers
Baseline cellular health, immune function, and oxygen-carrying capacity. This is where we look for anemia, infection, and bone marrow dysfunction that quietly drive fatigue, brain fog, and immune issues.
White Blood Cell Count*
Immune system activity and infection surveillance
Red Blood Cell Count*
Oxygen-carrying capacity and tissue perfusion
Hemoglobin*
Oxygen transport — a core indicator of anemia
Hematocrit
Proportion of blood volume occupied by red blood cells
MCV / MCH / MCHC
Red cell size and hemoglobin concentration — classifies anemia type
Platelet Count
Blood clotting function and bone marrow health
RDW
Red cell size variation — an early marker of nutritional deficiency
Metabolic & Heart Health
11 markers
Insulin resistance and cardiovascular disease share the same root. A standard cholesterol panel misses the early signals — and so does checking blood sugar without insulin. We test both systems together because they're connected.
Fasting Glucose*
Blood sugar at baseline — the most fundamental metabolic marker
Hemoglobin A1C*
3-month average blood sugar — standard marker for diabetes and pre-diabetes
Fasting Insulin
The early warning most doctors never order — elevated years before blood sugar rises
Uric Acid
Metabolic health, kidney function, and gout risk — also linked to cardiovascular disease
Apolipoprotein B (apoB)
The single best predictor of cardiovascular risk
Lipoprotein(a) — Lp(a)
Genetic cardiovascular risk factor — rarely tested, needs to be checked once
Homocysteine
Cardiovascular and neurological risk marker — reflects methylation and B-vitamin function
LDL Particle Size
Small dense LDL is far more dangerous — most doctors never check
Total Cholesterol / LDL / HDL*
Standard lipid measures — meaningful only with the advanced markers above
Triglycerides*
Elevated levels signal insulin resistance and cardiovascular risk
Advanced Lipid Panel
Particle number and size distribution — the full picture standard panels miss
Hormone & Thyroid Health
10 markers
Hormones govern energy, mood, cognition, weight, libido, and resilience. Most doctors check TSH alone and call it a day — missing conversion issues, reproductive imbalances, and adrenal dysfunction. We test the full picture.
TSH*
Pituitary signal to the thyroid — standard screening, but insufficient alone
Free T3
The active thyroid hormone — what your cells actually use for metabolism
Free T4
Precursor hormone — conversion problems are common and commonly missed
Overall testosterone production — affects energy, mood, muscle, and cognition in all genders
Free Testosterone
The bioavailable fraction — what your body can actually use
Estradiol
Primary estrogen — critical for bone health, brain function, cardiovascular protection, and mood
LH (Luteinizing Hormone)
Pituitary signal for reproductive function — key for fertility and hormonal axis assessment
FSH (Follicle-Stimulating Hormone)
Reproductive and menopausal status — evaluates ovarian and testicular function
SHBG (Sex Hormone-Binding Globulin)
Controls how much testosterone and estrogen is available to tissues — essential context for interpreting hormone levels
Vitamins & Minerals
12 markers
The micronutrients that power energy production, neurological function, immune regulation, and mood. These are functional markers — they tell us what your cells actually have access to.
Vitamin D, 25-Hydroxy
Immune regulation, bone health, mood, and hormonal balance — deficient in most Americans
Magnesium (RBC)
Intracellular magnesium — critical for sleep, stress response, and muscle function
Zinc
Immune function, hormone production, wound healing, and gut integrity
Calcium*
Bone health, nerve conduction, muscle contraction, and heart rhythm — regulated by thyroid and parathyroid
Phosphorus
Bone mineralization and energy metabolism — works in balance with calcium
EPA + DHA Index
Omega-3 levels in red blood cells — the most accurate measure of long-term fatty acid status
Omega-3 Total
Essential anti-inflammatory fats that support brain and heart health
Omega-6 Total
Pro-inflammatory fats — not inherently bad, but balance with omega-3 is critical
Omega-6/Omega-3 Ratio
The key ratio — elevated values drive systemic inflammation
Arachidonic Acid/EPA Ratio
Inflammatory balance at the cellular membrane level
Vitamin B12
Neurological function, energy production, and red blood cell formation
Folate (RBC)
Intracellular folate — methylation, DNA synthesis, neurotransmitter production
Iron & Energy
3 markers
Iron is one of the most common nutritional deficiencies we see — and one of the most overlooked drivers of fatigue, brain fog, hair loss, and mood changes.
Iron, Serum
Circulating iron available for immediate use
Ferritin
Iron stores — the body's reserve tank, and the marker most often missed
TIBC
How aggressively your body is absorbing iron — a signal of hidden deficiency
Kidney Function & Electrolytes
10 markers
How well your kidneys are filtering waste, maintaining fluid balance, and regulating the electrolytes that govern muscle function, nerve signaling, and pH balance.
BUN
Kidney filtration and protein metabolism
Creatinine*
Kidney function and glomerular filtration rate
eGFR*
Estimated kidney filtration — early detection of renal decline
BUN/Creatinine Ratio
Differentiates kidney from non-kidney causes of elevated BUN
Sodium*
Fluid balance and nerve function — abnormalities signal kidney, adrenal, or hydration issues
Potassium*
Heart rhythm, muscle function, and nerve signaling — tightly regulated by the kidneys
Chloride
Acid-base balance and fluid regulation — moves with sodium to maintain equilibrium
CO2 (Bicarbonate)
Blood pH balance — reflects kidney and lung function in acid-base regulation
UACR (Urine Albumin-to-Creatinine Ratio)*
Early kidney damage detection — identifies microalbuminuria before kidney function declines
Urinalysis*
Screens for kidney disease, urinary tract infections, diabetes, and other systemic conditions
Liver Function
6 markers
Your liver handles detoxification, metabolic processing, and protein synthesis. These markers reveal how well it's performing — and catch damage early.
ALT (SGPT)
Liver-specific enzyme — the most sensitive marker for liver cell injury
AST (SGOT)
Liver enzyme — also elevated in muscle breakdown
Alkaline Phosphatase
Liver and bone health indicator
Total Bilirubin
Liver processing capacity and red blood cell turnover
Albumin
Nutritional status, liver synthetic function, and inflammation
Total Protein
Overall protein status — liver function, nutrition, and immune health
Inflammation & Autoimmunity
3 markers
Chronic low-grade inflammation is the common thread running through heart disease, autoimmunity, depression, metabolic dysfunction, and accelerated aging. These markers detect inflammation and screen for autoimmune thyroid disease.
hsCRP*
High-sensitivity C-reactive protein — the most important systemic inflammation marker we track
Autoimmune thyroid marker — detects Hashimoto's years before TSH becomes abnormal
* Supported by current clinical guidelines for routine screening, including the 2025 ACC/AHA Hypertension Guidelines, 2026 ACC/AHA Dyslipidemia Guidelines, USPSTF Diabetes Screening Recommendations, and the 2025 ACC Scientific Statement on Inflammation. Our panel is physician-curated to include both guideline-recommended and functional longevity markers — so you get the full picture in one draw.
