Quick question. I have my yearly medical eval due this month because of my SI. I have been submitting my 24hr urine results due to a pheocromocytoma back in 03. So far, the results have always come back normal. I also do my yearly PFT to show the FAA that I can breathe... Now. My primary care physician can do both of these in his office. Is is acceptable if he does both tests and clears me to fly based on my results, or do the tests have to be done by an (endocrinologist = pheo) (pulmonologist = PFT)? I was usually going to the hospital for the PFT and the endocrinology office for the 24hr urine. Thanks for all the advice and answers.!
