There were 3941 reported PND tests of which there were 964 affected fetal results. Antenatal test coverage and Family Origin Questionnaire completion rates are high and increasing; the proportion of tests declined has decreased. However, there is wide variation in the timing of antenatal tests and completeness of follow-up and testing. Since 2014/2015 a lower proportion of PND tests are performed by the programme standard of 12+6 weeks. Results suggest that PND timing affects reproductive choices as those with an affected fetus identified by PND testing earlier are more likely to terminate the pregnancy.Conclusions The screening programme appears to be widely accepted as part of routine antenatal care in England. However, the timeliness of screening and subsequent PND testing has consistently not met programme standards. Improving timeliness would enable individuals to consider their options to make informed choices for their pregnancies at the appropriate time. This paper reports carrier rates for an almost complete cohort of women which provides important epidemiological information on the genetic profile of women in England. ER -
