Hi Colleagues, We are requiring papers / articles discussing and outlining the History of Pregnancy Testing . I have searched medline with little success. (We also have some information that toads were used for urine screening for pregnancy here in Queensland Australia . However we have been unable to find any documented evidence of this)Any help in locating a source for any information on this topic would be greatfully received. Many Thanks in advance.
