I love function. It gives me the ability to monitor my bios twice a year and make adjustments with food first and supplements if needed. I’m able to stay on top of my health and basically functional!

TripleZZZ
Very quick and efficient process from start to finish; very informative and affordable if you're into longevity and monitoring an array of blood factors. The tests are affordable and the app has an integration with Claude and the Apple Health app, so you can do indepth analysis of the data. I highly recommend. I just wish that there was a Quest lab in the Ann Arbor area.

Just having all of the days presented clearly and visually, along with the notes finally gives me a good picture of my health. Add-on tests can get expensive, but the basic membership is very worth it. Nice app as well.

Arun
I trust Dr. Hyman and his team to identify the important items to screen. This screen did me a very good service: my blood lead levels were very high this time vs no blood lead level in previous test. So I am acting on it. I could have missed it if I had not done this screening test and could have sustained irreversible damage to my health. The results give me an excellent big picture with details so I know how I am doing. Quest is an excellent and trustworthy lab so I trust the results. I appreciate Dr. Hyman for setting up something I can do to take care of myself without hassling with health insurance with its usual obstacles. The cost is very reasonable considering the number of items that are tested and screened so this is a very good value.
