CLIA-certified epigenetics laboratory True Diagnostics in Carlsbad analyzes DNA methylation patterns to calculate biological age through its TruAge testing platform on Loker Avenue West. The lab's proprietary OMICmAge algorithm measures over 900,000 methylation sites from a finger-prick blood sample, generating organ-specific aging data used by integrative practitioners including Quantum Functional Medicine to guide longevity interventions. Developed in collaboration with Harvard University, the third-generation DunedinPACE aging clock embedded in True Diagnostics' reports is the only commercially available pace-of-aging calculator validated across research and clinical settings. SymphonyAge scoring breaks biological age into 11 organ systems including brain, heart, liver, and immune function, giving clinicians granular targets for metabolic optimization. That organ-system approach aligns with the movement-based longevity programs at Longevity Physical Therapy in Bressi Ranch, where musculoskeletal health is tracked as a biomarker of functional age. The TruHealth panel adds 105-plus biomarkers covering antioxidant status, fatty acid ratios, and inflammatory markers to the methylation data, producing a multi-omic profile from a single at-home collection kit.
