Carrier screening for other reasons

Although most people we talked to had carrier screening during pregnancy, a few discovered they were carriers at other times in their lives. Some people found out after their new baby had been screened – their experiences are summarised separately in the section on newborn screening tests.

Another was told her screening test results were negative, and it was only later she discovered she was in fact a sickle cell carrier.
