Can someone explain what that means? I had blood work done a couple of months ago and my prolactin levels were slightly high. I did a repeat test last week and I just got my results and it said it was still “marginally high.” I didn’t speak to the doctor as she hasn’t requested a callback and has made a note that I’m already being referred to the fertility clinic. What can cause raised levels of prolactin? I don’t seem to have any “symptoms” of anything indicating there’s something wrong and my dr obviously doesn’t think I’m at death’s door or anything but I’m curious as to why it’s remained high.
