Further research on the routine adoption of Actim Partus and PartoSure to help diagnose preterm labour in women with intact membranes when transvaginal ultrasound measurement of cervical length is needed on the accuracy of the tests and their effect on clinical outcomes. Centres using the tests to help diagnose preterm labour in women with intact membranes are encouraged to take part in studies to address the research considerations (see the guidance sections 5.12 to 5.16). Data are needed on:
- the impact of gestational age on the accuracy of the tests
- how the tests affect clinical decision-making
- the effect of the tests on outcomes for mother and baby
