§ Mr. Chris ButlerTo ask the Secretary of State for Health what information he has as to the interval between a person being infected with HIV and the time when HIV antibodies can be ascertained by testing.
§ Mrs. Virginia BottomleyThere is usually an interval of six to 12 weeks from infection with HIV to the development of antibodies detectable by routine screening methods. In some individuals the appearance of antibodies may be delayed, but in 95 per cent. of cases they are detectable within six months.
