soulfeast, I have not discussed this with him specifically, so the correct answer is to say, "I don't know". But I can say that it has now been two years since my family first did the mycotoxin tests and at no time along the way did he ever suggest we do the HLA typing. As I have indicated before, Brewer's cfs patients almost uniformly test positive for mycotoxins, therefore all patients excrete mycotoxins, so these patients are all detoxing. At our last meeting I did ask about detox and he indicated that some patients might detox mycotoxins faster than others, but they will all get the job done if we can stop the input of myctoxins into the body. I was a patients of Dr. Shoemaker about 15 years ago and I was told I had the worst possible HLA type. Of course, my genetics have not changed, yet many years later I was excreting massive amounts of mycotoxins. (I was the record holder among Brewer's patients for the highest trichothecene level, but perhaps it has now been broken). So if mycotoxin testing is valid this would seem to be an absolute repudiation of the idea the HLA typing has any validity at all. I have read that Shoemaker takes the position that urine mycotoxin testing is not valid, but I have not seen an explanation as to why. Indeed, this really seems to paint him in a corner. To admit the test is valid would amount to an admission that the cornerstone of his whole mold theory has been wrong this whole time.
