Talk:Free androgen index

I cannot find any substantiation of the Wikipedia article assertion "Neither FAI nor free or total testosterone measurements should be interpreted in isolation; as a bare minimum, gonadotropin levels should also be measured." I have searched the NIH PubMed index of medical journal articles, but I found no substantiation, at least not in the context of men. Can someone provide substantiation? If not, should this assertion be deleted from the article?
 * This seems to be added by 68.146.75.110 along with quite a bit of other text. So you may also wish to check https://secure.wikimedia.org/wikipedia/en/w/index.php?title=Free_androgen_index&action=historysubmit&diff=317024151&oldid=309720069. Also this is not encyclopedic style, Wikipedia is not supposed to be an adviser for how to do things. Graeme Bartlett (talk) 05:59, 25 January 2012 (UTC)

Free T testing expensive and not readily available?
I would like to see a source for this as I personally have had total T and free T done for less than 30 euros. Anditres (talk) 11:53, 31 January 2022 (UTC)
