Information about antenatal screening tests - Section 8 – More information about antenatal screening tests

You can also get information about screening tests from your midwife or your hospital doctor (your obstetrician) and from the antenatal screening Wales page.

If you move home

If you move home during your pregnancy, please tell your midwife so that they can update your medical records.

Private tests

The quality of the screening offered by the NHS in Wales is monitored. Some women pay privately to have screening tests. Screening done by private clinics is not monitored by the NHS. This means that your midwife will have no information about the quality and accuracy of any screening tests carried out by private clinics.
