Extremely thorough. Got more answers in the clinical notes than I ever have from a physician. Very happy with the testing and answers.

Bill
Blood work is great, interface is pretty helpful in explaining biomarkers. New MRI and CT scans would be helpful if they weren't only partnered with ezra. Nearest testing facility is hours and multiple states drive from my location. I was hopeful to sign up for a scan, only to find out it was not actually available to me reasonably.

Kathleen
I took advantage of the discount provided through the Supp app (or else I would not have done it). I was impressed with the speed in getting results. The results indicated a potential health concern that I would not of known otherwise due to lack of tests in standard testing. It also alerted me to a few areas where adjusting my supplement routine could fix. Overall very impressed.

The comprehensive scope of testing and clarity of explanation of the results is excellent, including the clinician's notes after all results are in. Lots of good information for the money.
