Blood Tests for Food

Our Food Testing

            I need to tell you up front that there is NO entirely accurate testing available for foods.  This includes all forms of skin testing and blood testing.  The reality is that most blood testing for foods is about 50% accurate - at best. I used to perform a type of testing in our office called Provocation/Neutralization or P/N testing [1,2]. This test, developed by Dr. Herbert Rinkel, has been used for over 40 years in this country, and is the most accurate food testing available.  Like all food testing, itís not perfect, but it's certainly "more" perfect than other methods and is correct about 80% of the time.

            Since we use LDA immunotherapy, we donít have to test people for foods any longer.  This is because the LDA food mixtures are cross-reactive for ALL foods, so we donít have to find out about each and every food sensitivity or allergy our patients have.

            Remember, LDA is the only viable treatment in existence for the treatment of anaphylaxis to peanut and shellfish.

Since LDA is a very broad spectrum treatment that treats most food problems, we do very little food testing nowadays.
