I thought it would be advisable to ask Dr Dodds herself about Nutriscan and the lack of testing.
Here is the email I sent today:
Good Day Dr Dodds;
There has been some discussion about the above test and concerns expressed with-in a forum I am a member of. I will link below the thread for your perusal.
Essentially the concern is that at this point in time there are no published peer reviewed studies that validate this test.
I was hoping that you could give me an expected publish date for the research that underpins the accuracy and reliablility of this test.
