    Note: µIU/mL = mIU/L

    Wikipedadia quoting the The Immunoassay Handbook, Third Edition, says: normal for women is 2.8-29.2ng/mL or 59-619mIU/L. So your result is about 3.8ng/mL

    Have a read of the whole article if you like, a bit heavy going and way way way more than you ever wanted to know about prolactin!!!!.

      Note, i don't have access to the The Immunoassay Handbook, so cannot validate the accuracy or otherwise of the information in this article.

        Apologies for a reply to a question from 3-4 years ago: The original conversion for prolactin was based on a finding that 2.5 ug "pure" human prolactin protein (i.e., the International Std. 84/500) comprised 53 mIU. While the purity during this experiment may be questioned, the resultant conversion is:

        1 ug = 21.2 mIU
        1 ng = 0.0212 mIU
        1 ng/ml = 0.0212 mIU/ml
        1 ng/ml = 21.2 mIU/l

          Hi, Are you the original poster? - Thanks for coming back, your data means the Wikipedia article is accurate, if you used a different source. Are you able to put up enough info that i could use google to find a link to an article to indicate the validity of this? (Guest users can't post links, but i'll put it up in this thread for you).

          Thanks very much.
