Could I be only allergic to wheat?

I apologize if this is lengthy but I'm having trouble getting an answer from a doctor so I'm hoping someone will have a similar experience to me. 

I was diagnosed with celiac three years ago after doing an endoscopy. Since then I haven't eaten gluten aside from some minor slip ups here and there, but those slip ups don't always result in me getting sick. Sometimes I get realllllly sick and sometimes nothing happens at all. So fast forward this month, I had two coronas consecutively about 3 weeks ago (which contain barley) and nothing happened.. Then the next week I had ONE Mac and cheese noodle (not gluten-free) and had diarrhea for 24 hours straight it was awful. I got the suspicion I might only be allergic to wheat, seeing as I haven't really had problems with rye or barley, and tested it by eating an entire bowl of straight up barley. Nothing happened. I went to the doctor and she confirmed that its a definite possibility I might only be allergic to wheat and referred me to an allergist. After doing a skin prick test, I had no reaction to wheat, rye, or barley at all, so she told me she basically doesn't know if I am. So moral of the story, does anyone know a sure-fire way for me to find out if I am actually allergic to gluten or just wheat?

You could always have your gastroenterologist do the full celiac blood panel. That will give you a baseline for where you are now. It can take a month or more for damage from eating gluten to do something noticeable with your blood tests. If you have been gluten-free your blood tests should be normal.

Keep in mind that the gluten in barley could be doing damage even though you don't feel it. Then one day you can be wondering why you always feel sick and just avoiding wheat doesn't help.
