Standard lab reference ranges are built from the general population, the majority of whom are metabolically unwell. We use tighter, evidence-based optimal ranges drawn from longevity literature and preventive-medicine practice, applied to the same blood draw with a higher threshold for action.
ApoB, Lp(a), fasting insulin, HbA1c, triglyceride/HDL ratio. The markers that actually predict cardiovascular events, not just the ones on a standard panel.
hs-CRP, homocysteine, ferritin, GGT. Chronic low-grade inflammation is the common substrate of most age-related disease. We track it precisely.
Total and free testosterone, estradiol, progesterone, SHBG, DHEA-S, cortisol. Sex- and life-stage specific ranges, not population averages.
Vitamin D, B12, folate, omega-3 index, magnesium RBC. The substrates your brain depends on day to day.
Liver enzymes, kidney function, complete blood count, thyroid panel. The organ-system baseline that protocols build on.
Ferritin, zinc, B-vitamin panel, vitamin D 25-OH. Repletion before optimization.
Optimal ranges are drawn from peer-reviewed literature in cardiovascular medicine, endocrinology, and preventive nutrition. Protocols are reviewed by board-certified physicians on our clinical advisory team before release. Where the evidence is uncertain, we say so plainly inside the app rather than picking a number and pretending.
