Screening tests in pregnancy


As Soon As You’re Pregnant

Women are encouraged to book their midwife appointment as soon as they know they are pregnant. 

Some screening tests, including those for sickle cell and thalassaemia, are best done before a woman reaches 10 weeks of pregnancy. This is because further tests may be needed, and decisions made about ongoing care.

Please visit for further information and advice.

You’ll be offered some screening tests during pregnancy to try to find any health conditions that could affect you or your baby.

The tests can help you make choices about further tests and care or treatment during your pregnancy or after your baby’s born. All screening tests offered by the NHS are free.
