Saw your link, did your test and here's my feedback.

No "share" or "download" button in the app? Sure, "apps are cool" and all that - but what about folks who want to archive or share their health data? AFAIK literally no provision to share all those nifty biomarkers with my doctor (except many, many screenshots)?

Nowhere in the "how to get blood test" email instructions does it bother to mention a urine sample will also be needed. Kinda useful to know if you should not pee right before heading to the lab.
