The whole process was very easy, booking my blood work appt, getting my results, receiving explanations about my results

Scheduling my labs couldn’t be more simpler. The Function Health website is easy to navigate, so I can quickly select a Quest Labs location near me through the Function Health website and schedule my appointment. It is also incredibly easy to schedule additional test at a very reasonable cost. There are some markers that I may want checked more frequently, and Function Health gives me that opportunity without having to request it from my Primary Care Physician. This is one of the best investments you can make in yourself because you can start to take charge and monitor your own health and identify deficiencies or issues before they create larger and more costly health concerns. The Clinician Notes provided at the conclusion of your labs are also very thorough and give great insight into what your results really mean for you.

Function Health tests things that regular doctors do not. The results arrived quickly, and the explanations were very helpful. I also appreciated that they had both "in range/out of range" and "optimal" levels of each test explained. I also appreciated the clinician's note that I got after all the test results came in. I believe knowing these results and staying on top of them will allow and motivate me to proactively be the healthiest person that I can be throughout my life.

A+. Half the price I was paying for bloodwork through insurance and I get 2 tests/year. And more tests I’d have to pay 1000-3500 for. Further illustrates the us healthcare system is a complete scam and better services can be provided for way less.

The only thing that could have made my experience better is letting me know where Quest was located. I drove up and down the street looking for the address and found out it was INSIDE the Safeway store.

Kelsey
My lab tech told me these tests would cost upwards of $4,000 and Function is a fraction of that! The entire process is extremely easy - 10/10 would recommend using this company.
