How reliable is prolactin considered to be for distinguishing beteen seizures and pseudoseizures

Still not finding much, found this though which was what I thought had been the case:

 

"Pseudoseizures. Often a manifestation of psychologic illness, pseudoseizures are usually poorly stereotyped, varying in form and duration. Most epileptic seizures last less than 3 minutes, but pseudoseizures may have a much longer duration. They are much more likely to occur during times of stress and do not typically occur while alone or during dangerous activities such as cooking or drinking. Without capturing a spell on EEG, it can be difficult to differentiate pseudoseizures from epileptic seizures. Comparing a prolactin level drawn within 15 minutes of a spell to another drawn 24 hours later can be informative. Epileptic seizures are usually accompanied by a significant rise in prolactin level over that of the normal circadian variation. However, a normal prolactin is not helpful because not all seizures are associated with a rise in prolactin level."

Am stilll uncertain which seizures may not be assoicated with elevated prolactin, or how one would in those cases determine if the seizure was a real one or not

 

Will keep looking, though the question is apparently of more personal than general interest
