I've gained a lot of insight into my health risks associated with high cholesterol through the lab tests that I wasn't getting through my regular doctor. I've learned through a high Lp(a) result that I'm genetically prone to heart health risks. This is enabling me to have a more productive discussion with my doctor and to advocate for my healthcare.

Though it uses AI, it is hands down the best health assessment tool out there. It is the doorway for change that can lead to preventing metabolic and other disease.
