That seems quite reasonable. I convinced my doc to test my total IGE, which tells if my body is reacting to "something". And that was high. 250 or so I think. Not as high as my daughter, who is allergic to milk, egg, cats, dogs among other things, her total IGE is about 2000. I haven't gotten around to exploring what my body might be reacting to yet though.
Was it your doctor who was able to order the IGG test for you? What kind of things were you most allergic to? Do you have any luck taking antihistamines like Benadryl?
