I was considering writing to Dr. Myhill to ask if any doctor or lab in the US is doing the detailed mitochondrial testing that she pioneered in the UK. I was pleased to see that she now offers a service whereby patients can have blood drawn here in the US and air-mailed to her office for the tests. From there the blood is sent to two different labs for the various panels. On receipt of the lab reports, she'll forward them to a patient's physician along with her recommendations on supplements. I think the total cost is around £250 to £300. I'd like to hear from anyone who has had these tests done. Was the information provided helpful? Did you see an improvement from taking the recommended supplements?
