I find PEM/PENE to be vague and subjective and, as stated in this post, I am opening a new thread. It is my current understanding that 2 consecutive CPETs, separated by a 24 hour period, is the golden standard for objectively assessing PEM/PENE. I would like to undergo such a test in a private clinic, where healthcare professionals will probably not be familiar with ME/CFS. Therefore, I would need to know exactly what to ask them for as far as setting up the tests. I would also need to know how to interpret the results later on, on my own. Could you please help compile a list of up-to-date peer-reviewed articles where I could find this information?
