Yes i had that test done by my neuro and the only this off is elevated igg.
He also did random urine with it.
My immunologist did a hiss panel that showed elevated iga, very high ige and elevated igg.

Never had that infectious testig. Which specialty showed I go to that can evaluate these new blood test as Neuro, gp, and allergist don't know what the elevation signifies!

Btw.. Great seeing you in YouTube :-)
