UK NSC screening recommendation
Screening women for vasa praevia during pregnancy is not recommended because:
- it is not known how many babies are affected by it in the UK
- it is not known how accurate screening tests are at detecting it
- screening may mean some women are offered an early caesarean when they do not need one
- some women may be reassured by false tests and still have a problem during delivery
