Many women’s groups ‘made serious attempts to reach local working class women based on their own particular needs.’121 Pregnancy testing was one of these needs and, for the predominantly white middle-class activists, it provided a means of reaching a diversity of women, including those who had never before talked to anyone about contraception, anatomy or reproduction, and who would otherwise not have made contact with a women’s centre.122 In this regard, it is helpful to think about feminist pregnancy testing in relation to comparatively well-studied instances of health-related activism. The Black Panther Party, for instance, used Sickledex, an inexpensive, portable diagnostic test for sickle cell anaemia to not only raise awareness about the genetic disease, but also recruit members and garner support for related causes.123 A.I.D.S. activists, often educated white middle-class men, acquired the language of immunology and learned to translate it into the vernacular, much as feminists had done before.124 And the birth-control clinics set up by Marie Stopes and others, including Lella Secor Florence in Cambridge, confronted similar challenges in reaching the desired clientele, including rural and working-class women.125
the phrase I'm looking for the source of is "translate the x into the vernacular"
