Allergy Tests

In the past I found a study showing that testing of foods doesn't work because the proteins used in testing are the raw protein for each ingredient which doesn't necessarily tell you what will or won't happen with the cooked version.

Again, today, I am running across the reverse scenario to the above in that there are also papers showing a cooked protein may not be a trigger when "uncooked" proteins are, such as with egg:
"CONCLUSIONS: The majority of subjects with egg allergy were tolerant of heated egg. Continued ingestion of heated egg was well tolerated and associated with immunologic changes that paralleled the changes observed with the development of clinical tolerance to regular egg."
