Where should I go?

Only place you can do the testing now is the Univ Of Minnesota.

The U of Minnesota halted DDC from testing further. Now they can charge whatever they want without any competition. Real nice especially with no further research currently.

You can also use Paw Print Genetics. They do a lot of other tests too.

Paw Print Genetics is a newer lab in the US. They can test Labs for PRA-prcd, EIC, and CNM. They have lots of other tests also, but less common ones. They do not offer RD/OSD; but maybe they would if enough people asked for it. They seem to have a very good testing protocol (in writing anyway). I haven't used them myself.

If U of MN halted DDC from EIC testing why wouldn't they halt this new lab from doing so?

Different method.
