Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: Thank you for the advice! We havent thought about pheochromocytoma. It does seem to line up. How does that get diagnosed? The website I was reading just a minute ago said a 24-hour urine test which she did when her GI doctor wanted to test for carcinoid syndrome/neuroendocrine tumors with a 5-HIAA urine test. I think they were only testing 5-HIAA though and not anything else so not sure if thats what they test for when checking for pheochromocytoma. Shes also had a kidney ultrasound and two abdominal (including kidneys) CT scans with contrast. Would they have shown up on those or is it one of those things they have to be specifically looking for?Shes reached out for therapy. She actually is a counselor herself so we tend to think she had the proper coping skills herself but as time has gone on with this, she has reached out to former colleagues, specifically to try to schedule EMDR therapy which has been very helpful for her in the past.The tricky part with it being related to anything COVID-related is she's never actually tested positive for COVID. So we don't know that she's had it even though when she searches for others dealing with her symptoms on reddit, it often takes her to posts in the covid longhaulers subreddit.. ### Response: 5-HIAA testing is for carcinoid syndrome, not pheo.
