Biomarker Tracking

Summary

A short, well-chosen blood panel — ApoB, HbA1c with fasting glucose (and, if you can, fasting insulin), ferritin, vitamin D, hsCRP, and TSH — checked roughly yearly tells you almost everything a healthy person needs to know about their trajectory; the "full body" 100-marker panels sold by direct-to-consumer labs mostly generate false alarms, anxiety, and follow-on tests, while a handful of genuinely useful markers (ApoB, fasting insulin) are paradoxically *under*-ordered by routine care. ---
