No-call cell-free DNA result in a higher-risk pregnancy — structured clinical encounter

Station brief (candidate)

You are the paediatric registrar on the antenatal liaison round. Aisha is 37 years old at 11 weeks gestation. Her cell-free DNA screen returns a no-call result due to low fetal fraction. She asks whether the baby is fine and whether she needs any further testing. She lives two hours from the nearest diagnostic service, has intermittent phone reception and limited leave from work. You have 12 minutes with the patient and 5 minutes for examiner discussion. ^{[1] [18]}
