Sherri T.
Flexible for scheduling and the results have proven to be very helpful. Brief insights to explain each blood test result. Highly recommend. I also appreciate the “effective age” suggestion as a wrap up to the assessment.

Timely, accurate communication. Always helpful, cordial and friendly. Any problems or mistakes I encountered were caused by human error from another organization or business not from Function Heath FH personally provided information necessary to resolve issue without blame. They have been a pleasure to work with.

Everything about the process was simple and explained well. Ordering and setting the lab appointment was fast and the results were delivered in the time frame I was told they would be. Very insightful information and I look forward to doing the follow up labs for comparison. I would definitely reccomend Function and have.

I have recommended this to so many people. The cost for the tests and results I received were fantastic. Having access to the clinician report and all my test results, along with explanations is really great. The protocol feature/AI feature can be glitchy but I have not relied on that.

Kathleen M.
Using Function Health is highly recommended! Me cardiologist sent me to get bloodwork through Function Health. I was blown away with all of the information you get back from the tests. The testing is extremely detailed. If the test comes back they dig deeper to see where the issue developed. I have given my regular practitioner a printed copy and we sat down and reviewed all of the results. It is something I will use every year. It helped my cardiologist and my practitioner make changes and give me further advice. Fortunately there was no indication of cancer or other issues. Kathleen

Professional! Convenient! Flexible Scheduling. Excellent clinical notes! After using the service twice, it has been everything it was advertised to provide. I appreciate clear, concise objective data I can analyze with additional insight from the clinical notes. Absolutely recommend for anyone who appreciates seeing all the data and make your own choices to share/consult.
