Could someone help me find the best way to test prolactin in blood? For consistency, I have been testing it at 8am, in a fasted state. I've been doing this for years. The value will not budge below 14 ng/mL no matter what I do.
The one time I went to test non-fasted, the result was even worse (28 ng/mL). After getting the result, I read a study showing that a spike in prolactin is seen right after eating.
What would the ideal process to test pituitary hormones? Would it be best to have breakfast, a bowel movement and all, wait a few hours, and then go test before lunch time?
I understand a 12-hour fast will drive pituitary hormones up, but at the same time, pituitary hormones like LH, FSH, prolactin, are known to be lower during the rest of the day.
What do you think it is the true gauge of prolactin in the blood? Early morning fasted, early morning non-fasted, mid-day hours after breakfast...?
For those wondering, I've been very judicious about the day I go test prolactin early in the morning. For this last round of testing, it was a quiet week, no stress at work, good night sleep the night before and all that.
Thank you!
