How to use
Book your blood draw at a partner lab or schedule an at-home visit with our phlebotomist. Your results are added to your health profile and reviewed by our medical team.
Why add an extra blood draw?
Health isn't static, and neither are your biomarkers. An additional blood draw allows you to measure changes sooner — whether you've adjusted supplements, made lifestyle changes, or want to validate progress after a specific intervention. This add-on gives you timely data, so decisions aren't delayed or based on assumptions.
