Advanced Blood Testing & Metabolic Assessment

JYZEN's on-site Biometrics Lab in Mill Valley provides comprehensive diagnostic blood testing and metabolic assessments, delivered by a dedicated in-house phlebotomist and medical team. The lab panel menu spans complete metabolic panels, CBC, lipid panels, inflammatory markers, thyroid and liver function, glucose and insulin sensitivity, vitamin D, iron studies, and advanced cardiovascular risk panels including the Boston Heart Advanced Cardio Risk Panel with genetic lipid analysis. Functional metabolic testing includes resting metabolic rate measurement, VO2 Max cardiopulmonary assessment, InBody body composition analysis, grip strength, HRV, spirometry, and mobility evaluation. Results are interpreted within JYZEN's integrative framework and used to build individualized optimization protocols.

JYZEN's Biometrics Lab, located at the Mill Valley clinic in Marin County, provides one of the most thorough in-clinic diagnostic assessment platforms available in the San Francisco Bay Area for clients pursuing a data-driven approach to health optimization. The lab's testing menu has been designed to feed directly into JYZEN's four-stage care model — diagnostics informing the detoxification, optimization, and maintenance phases — ensuring that every intervention is grounded in objective biomarker data rather than general protocols. Blood testing at JYZEN covers the full spectrum of metabolic, endocrine, cardiovascular, and nutritional markers. The complete metabolic panel assesses kidney function (creatinine, BUN, eGFR), liver enzymes (ALT, AST, ALP, GGT), electrolytes, and glucose. The comprehensive blood count (CBC) evaluates red and white blood cell populations and platelet counts, providing a snapshot of immune status and oxygen-carrying capacity. Lipid panels include standard total cholesterol, LDL, HDL, and triglyceride assessment, with advanced cardiovascular risk stratification available through the Boston Heart Advanced Cardio Risk Panel — a genetics-informed panel that assesses apolipoprotein levels, lipoprotein particle size and density, and genetic variants influencing cardiovascular risk beyond what standard lipid panels reveal. Inflammatory marker testing includes high-sensitivity CRP and other markers that can indicate systemic chronic low-grade inflammation, a key driver of accelerated biological aging. Thyroid function panels assess TSH, free T3 and T4, and antibodies where indicated. Insulin and HbA1c testing provide a detailed picture of glucose metabolism and metabolic flexibility, relevant for clients with insulin resistance, pre-diabetes risk, or metabolic syndrome. Vitamin D (25-OH D3) and iron studies (serum iron, ferritin, TIBC, transferrin saturation) round out the nutritional assessment. Specialty panels available at JYZEN include mold toxin screening and heavy metal testing, reflecting the clinical team's expertise in environmental medicine and chronic illness evaluation. Beyond blood panels, the Biometrics Lab offers functional metabolic testing: Resting Metabolic Rate (RMR) measurement quantifies daily caloric expenditure at rest using indirect calorimetry, enabling precise caloric and macronutrient targets; VO2 Max cardiopulmonary exercise testing measures aerobic capacity and cardiovascular fitness, a strong predictor of longevity outcomes. Body composition assessment combines InBody bioelectrical impedance analysis with skinfold caliper measurement for multi-method accuracy in tracking lean mass, fat mass, and visceral fat. Heart rate variability, grip strength, spirometry (lung function), and mobility assessment complete the functional performance picture. All results are interpreted by JYZEN's medical team — including board-certified integrative physicians and a naturopathic doctor — within the context of the client's individual health history and goals. The Biometrics Lab serves both standalone diagnostic clients and those enrolled in JYZEN's 90-Day Metabolic Reset or Longevity Program tracks.
