Just had skin prick allergy testing and allergist said it was inconclusive because I reacted to all 40 allergens equally. Whats the next step in test?

In brief: Inconclusive or not

Usually there is a positive control (histamine) and a negative control (glycerin) when you have a skin allergy test.
If you don't react to histamine then lack of response to other antigens is inconclusive. However, if you are positive to histamine, negative to glycerin, and positive to all antigens tested then that means you are highly allergic and would probably benefit from desensitization
