Questions of A More Technical Nature

Blood Type and ELISA


I am type O. Last year my doctor ran an Elisa Allergy blood test because he suspected that I had some food allergies. The test showed the I was highly allergic to the exact same foods that ER4YT says I should not eat. Is this a common occurence? Is it further evidence supporting the concepts behind ER4YT.


It is common enough to make me think many of the other allergy determination methods, such as rotation dieting, ELISA and RAST are not really worth the extra effort, and indeed will tend to generate more false positives and false negatives than they will pinpoint foods not identified via ABO blood type. Most are also very expensive.

The Ask Dr. D'Adamo internet advice column ran from 1996 to 2009, at which time Dr. D'Adamo's teaching and programming responsibilities no longer allowed him to devote time and resources to directly answering visitor questions. However we've recently reorganized this treasure-trove of material and made it again available to his readership. He occasionally posts new entries. These are marked with a NEW tag.
