Longevity & Optimization Home Test Kit

$299

The Longevity & Optimization Home Test Kit tracks the markers most tied to healthy aging, so you can optimize stress, hormones, and inflammation over time. It measures 5 markers — Cortisol, DHEA-S, HS-CRP (inflammation), Testosterone, and Vitamin D — ideal for proactive, performance-minded adults. Collected at home in minutes with a premium self-collection device — no clinic visit and no traditional needle stick — then mailed back in prepaid packaging. Physician critical-value review included at no extra cost: a licensed physician reviews your results solely to identify any critical value — an out-of-range result that may be concerning — and if one is found, you’re notified directly so you can seek further medical evaluation. Knowingly Healthy and Test Smartly Labs do NOT interpret, diagnose, treat, or recommend any medical treatment; the physician’s role is strictly limited to flagging critical values. Your results are provided for informational and wellness purposes only and are not a substitute for professional medical advice — you should consult your own medical professional to interpret your results and decide on any next steps. (Test-ordering requirements vary by state; where a physician order is required, it’s arranged for you.) Part of the Knowingly Healthy line, powered by Test Smartly Labs — a direct-access laboratory with 15+ years of trusted service, physical patient locations, and live customer support. Unlike marketing companies that broker your sample to third-party labs, Knowingly Healthy is real lab medicine, processed at a top reference laboratory.
