Morning Prof

Thanks for your feedback. I just have a couple of things to add.

We have been to a paediatric allergist who tested him for every possible allergy. She did skin and blood tests. There was not one reaction. But this was done over a year ago. Could things have changed? I just don’ t want to have him go through all of it again if unnecessary. I''m also not keen on taking him back to her as she was also the paed who diagnosed him with primary cilia dyskenisia by leaving a message on my cell. I found it to be quite unprofessional.

The other thing is, he eats nuts everyday. He does not like meat, so I give him some cashews, hazelnut etc. Obviously I did not give him any today. Could this have caused him now to be allergic? Could I just start with a general bloodtest, would that show an allergy is present, or do we need to now test for all the specifics again?

There is no doubt that your son has recently had an allergic reaction. It is possible that the cause of his allergic reaction was not tested for at his previous visit to an allergist. He needs to be tested specifically for tree nuts, not all tree nuts,but certainly hazelnuts and almonds and also peanut. He should also be tested by a new allergy test called a CAST test. The CAST test is done for possible allergies to colourants and preservatives. He certainly should be tested for possible allergy to blue, red and yellow food dyes and to sodium benzoate on the CAST tests.
