I'd send Glenn a PM and ask him. He talks to his expert doctors about all the tests, and he is very informed about them.
I do know that I've seen him post here that some doctors do not use the punch biopsy because they don't "trust" it .
I think but do not quote me, that he mentioned Mayo as one place that doesn't like the punch biopsy yet.
And it is true, it is not cast in stone... it is rather new, and needs good interpretation etc.
