I am male, 44. I have much information about how the immune system works.
IgE and IgG tests tell whether you are allergic...or...intolerant. Intolerant reactions can happen 48 hours after eating the offending food.
Anyway, I just found this site. I have been living with intolerance to milk, egg, peanut butter, wheat, soy, corn, yeast.
