I am a 55-year-old asthmatic.  Next week,  I have an allergist who wants to give me 378 allergens (all at one time) for allergy skin tests. He says it is safe, but I read that 40-45 (AA&FA) is the range.  So far, I have not read anything about the consequences of receiving over 300 allergens at one time.  What would be the immune/autoimmune response to being given this this amount all at one time? Could this excessive amount cause damage?
I think you are advice for skin pricking allergy test. Need not worry. Allergen of allergic skin pricking test if very low. Other alternative is to go for allergy screening test in which General and specific IGE is measured in blood.
