What could my DS be allergic to?

[SalviaOfficinalis]

My 1yo DS has had one allergic reaction (rash all over and facial swelling). It happened 10 mins after having a small taste of my Indian takeaway. He had a bit of naan, paneer and chicken. I cut the pieces of paneer and chicken to remove the spices from the outside, but would have been traces left.

He’s had negative skin pricks for tree nuts, sesame and coconut. Now awaiting blood results to confirm negatives.

He eats peanuts, milk, eggs, wheat. He’s had a few Indian spices from my cooking - turmeric, coriander, cumin.

He hasn’t tried (that I’m aware of): shellfish, celery, mustard.

Does anyone have any unusual allergies? Any ideas?

I stick to giving him things I know he’s had before so it does limit us and worry me. I wouldn’t feel safe just giving him whatever we’re eating.

Prob not specific to the meal you had but my DS is allergic to egg white.... he can have whole egg, cooked into a cake for example but couldn't have egg white on it's own in something like meringue.

Always found it weird one... how it being whole egg is fine but not if egg white on its own.....

Thanks for posting. He has daal at home quite often (including since the reaction) so not lentils.

Re the ingredients list, it was a big order and I didn’t order it so don’t know which dishes it was exactly. I do understand why it’s being suggested but I’d still be questioning which of the 50 different ingredients it was - and it could always have been cross contaminated with something not on the list.

Thanks for everyone’s help, I think I just have to accept that we might not find out until it happens again if all his blood tests come back negative.

A cashew nut allergy affects 1% of the population so it's a fairly likely contender

Cashew nuts allergy
is not uncommon

Yes! Almost anything can be an allergen. And there are some very strange allergies around that have only recently been 'discovered' or identified - I have a form of exercise induced anaphylaxis, where I'm allergic to a specific protein in wheat gluten, but unlike to react unless there's a co-factor, other 'newish' ones are lipid transfer protein and alpha-gal.

I was going to suggest lentils as well as my DS was intolerant of these and peas, too when he was young. It took ages to work out what it was, but thankfully he has grown out of it. It was an intolerance, provoking a rash and hives on his face rather than a true allergy. The only way to find out is to do an exclusion test, removing then reintroducing foods or ingredients one by one.

Forgot to add, my dc's allergy doctor tested him with 120+ allergens from single blood test, found out unexpected allergies too.
For prick test, if I want my dc to be tested for unusual allergen, I bring actual thing with me, and the nurses and doctor are happy to test for him.

@grapehyacinthisactuallyblue was your DC’s testing NHS (if you’re in the Uk) or private?

Chick peas? My son has anaphylaxis to them.

Also, the RAST blood tests as less reliable than skin prick tests.

NHS. London Hospital.
