I am so impressed with the tests that were done as they were a deeper dive than my PC doctor would do and an amazing value. The clinician notes are terrific, not boiler plate but referenced my health profile and "connected the dots" to use their terminology.

For years, I was dealing with mystery neurological issues that no doctor could quite pin down. As a runner, former athlete, and yoga teacher, watching my mobility drop while weakness and pain took over was a total plot twist I didn't sign up for. Turns out, despite my "clean" diet, my body was secretly running on pure inflammation. Functional testing finally gave me some real answers, showing me the key nutrients my diet was actually missing. I’m not 100% cured of my neuropathy, but I’m sitting at a glorious 95% better—and I’ll take those odds any day! Beyond the day-to-day relief, getting negative cancer screening results brought a massive sigh of relief. Doing Alzheimer’s and MTHFR testing also completely shifted how I manage my stress and nutrition for the long haul. Oh, and the grand finale? Finding out my biological age is nearly 10 years younger than my birth certificate. Mind = officially blown.

This my second year with function health and I really comforted with the fact that not only do they take a deeper dive in labs not ordered or covered by physicians/insurance, but how function responds in great detail about every lab value. Clinical notes are provided that offer advice on supplementation and dietary intake to help with establishing optimal lab values and overall good health.

The blood testing in Quest in Sante Fe went very well. Professional and efficient and friendly staff. Much better than our experience there last year.
