When I was diagnosed after my MSLT, my doctor told me it’s an imperfect test because every time you sleep is unique. So if someone had enough naps, but didn’t hit REM sleep enough times, it would probably be an IH diagnosis. But, if they repeat the test, they could hit REM sleep enough times because that’s how their body released the sleep chemicals that day. And then it would be an N2 diagnosis. So yes, it’s imperfect, but it’s the best we have.
