All the tests included with the $499 should be covered by your health insurance. I wouldn't sign up again for this unfortunately........... If you do not have health insurance it might be worth it.

I paid nearly $800 for functional health testing—including multiple lab visits—only to learn that the lab mishandled my samples and now expects me to come back and repeat the process. I’ve made every effort to reach them—calls, emails, texts, even in-person attempts—and the response? Silence. No call backs. No replies. Nothing. This company takes your money, disappears, and leaves you to deal with their mistakes. There’s absolutely no accountability, no communication, and no access to anyone in management. If something goes wrong—and clearly it can—you’re on your own. Avoid this place. They do not care about your time, your health, or your money. Look elsewhere. Hopefully one of their competitors understands what real customer service looks like.

Horrible experience. 2x blood draws at quest with many vials. Really bad technology dashboard. Experience falls short after the blood draw

Trash, garbage, go elsewhere. Take your $500 and have a nice dinner, don't waste it here. No testing location within 5 hours of me, no way to contact a human, AI chat useless. Royally pissed.

Stay Away- I did the first two tests more than one month ago. Received a handful of results within the first few days and have not heard anything else since. There is no customer service phone number, and the chat gives you some standard non-sense answers. These folks are way above their head, and the operation is a shamble. They don't have the operational infrastructure to support their business promise. It seems like the only part of the operation they have a handle on is to onboard you and collect your money, but nothing is set up for delivering their part. Don't waste your money.

I canceled my membership online about a week before it was due to renew and today I received a charge on my FSA card for $499! I tried calling the only number I could find for them and it went to voicemail, so I went online (again) and canceled it again - requesting a refund! This company is not what it says it is - you can't even text with a live person, it's all AI generated. BEWARE!

Wait time for test results is approaching 2 months, followed by another 2-3 weeks for clinical notes. I question the accuracy of the results given how long they sit around before being processed. When contacted, customer service is vague and noncommittal. Yet they continue growing the business despite these problems.

Easy to read. WAY to long to get results. You can go direct and get results from almost all of these test by Ultralab or other places in a matter of days. Its unclear to me how and why it takes weeks or months to get some results. Having worked in the lab samples sitting around for so long are suspect to storage issues and chain of custody and degredation
