Interventions

Ultrasound DIAGNOSTIC_TEST

All study interventions/procedures will happen during the participants routine clinic visit in which they will receive their routine Ultrasound scan, followed by an additional research scan, which will take approximately 2-3 minutes. A blood sample will also be taken from participants as part of their routine pregnancy care. Residual blood from the same sample will be used to conduct an additional test to quantify Placental Growth Factor (PlGF). Participants will also be asked questions about their relevant medical history and demographic data which is also routinely collected as part of their pregnancy record.

Eligibility Criteria

• Age: 18 Years+
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Pregnant women attending the Fetal Medicine Foundation for their first-trimester screening scan

You may qualify if:

• Pregnant
• years of age, or older
• Presenting for first-trimester combined test screening between 11+0 and 13+6 weeks of pregnancy
• Participant is willing and able to give informed consent for participation in the investigation.
• Able to understand written or verbal English and able to access methods of translation.
• In the opinion of the investigator, the participant is not at risk or under stress or limited in their ability to participate in the study activities.

You may not qualify if:

• Participant with a multiple pregnancy (more than one viable fetus) discovered at the scan
• Participant with a non-viable pregnancy discovered at the scan (no detectable heartbeat)
• Pregnancies with major defects identified during 11+0 to13+6 week scan
• Any pregnancy subsequently found to be chromosomally abnormal as a result of either prenatal or postnatal testing
