Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: I greatly appreciate this response as its extremely informative!The white plaques were never followed up on unfortunately. Her blood in her stool cleared up shortly after so she let it go.I definitely agree with you on the autoimmune thoughts. I had no idea there were so much more to test for. What kind of specialist would she see who would run those kinds of tests and how does she approach it with that doctor? Just tell them she wants to be tested for everything?. ### Response: A lot of those blood tests I mentioned any primary can order as well as the synovial ultrasound.Its hard to approach an MD about specific tests but I think its worth asking. It just depends on how you think your doctor is. I have patients ask me for specific tests pretty often and we just make a joint decision on if its worth it in shared decision making.As for which specialty? rheumatology and GI would be the ones in my opinion..
