Time taken for non-parent relatives to have carrier testing after the diagnosis of a child with CF through newborn screening. ^*This column represents relatives who have been tested in the eighth year after their family member was diagnosed with CF. The database search was conducted in March 2009, and hence only tests conducted in the first quarter of 2009 have been included and this column does not represent a full year. One relative was tested 39 months before the birth of the child in this study. This was because another child in the family was born with CF 15 years previously (first cousin once removed from the child in the present study). The relative (carrier risk of 1 in 4, based on relationship to child in this study) was tested when she was pregnant, which was before the birth of the child in this study.
