In the case of solar urticaria, there is also activation of some antigen in the skin by ultraviolet light which then causes an ige reaction.

Thus, it is allergy in the sense that experts in understanding this part of the immune system treat these conditions, but no allergic antibody ...Read more

Is black tattoo ink hypoallergenic? Are allergic rxns to this rare for those with history of allergies? (AR, chronic urticaria....)

If you're concerned, ask for a test spot in an inconspicuous area 1-2 weeks before a full tattoo as a precautionary measure. ...Read more

If you strictly avoid these foods, then an Allergist can perform testing to begin to quantify risk and this can be followed by supervised food trials to confirm absence of allergy. ...Read more
