Interesting.
I wonder how they arrived at 0602 and 0603, for I think serology cannot resolv the differences. Could be HLA DQ by PCR plus HLA DR by PCR.

Which reminds me, some of Dr. Shoemaker's patients have had DR testing done, and discussed it on forums, and I ran across it. Gluten sensitive persons only get DR testing done.
Now certain DR types are very sensitive to mold.

Looks like your DR types are DR13 which is also DR 52 and DR 15 which is also DR51. You can check what that means at the chart in wikipedia, HLA DR page.

When googling shoemaker mold rosetta, it clearly says HLA DR by PCR.
Now I just have to find his chart somewhere.
