Biomarker Tracker logs your labs against reference intervals and, where the evidence supports one, a named optimal target — across 20 markers spanning lipids/cardiovascular, glycemic, inflammation, organ/metabolic and micronutrient panels. Every range links to its source guideline or PubMed citation, and where no defensible optimal exists, the tool says so plainly instead of guessing.
Everything is stored only in this browser's local storage — nothing is uploaded, there are no accounts, and you can export or erase your data anytime. The tracker also includes an "advanced diagnostics, explained" panel covering DEXA, coronary artery calcium (CAC) scoring, coronary CT angiography (CCTA), whole-body MRI and multi-cancer early detection (MCED) blood tests: what each one measures, who current guidelines say it may help, and its honest limitations.
