Cohen vs. DiMauro on fresh vs. frozen

[Guest guest]

Since I'll be having a biopsy in November, I've been looking into the

fresh vs. frozen question. I called Dr. Cohen's office and a nurse

called back and said they only do fresh ones. They believe it's much

better. Then I called Dr. DiMauro (who I actually spoke with

directly). He was convinced that frozen is fine in the vast majority

of cases.

I liked Dr. DiMauro's answer better for the pragmatic, non-scientific

reason that I'd have to travel to get a fresh biopsy and travelling is

very difficult for me. But I know some of you have had both types

done. Did you get different results with each type? If so, could the

different results be attributable to the specific type of mito you

have? Or, could it simply be that people with mito test differently

at different points in their illnesses? Or, do you believe that the

fresh-frozen issue was the key?

Best,
