Screening Tests in Pregnancy

Updated: Apr 16, 2022

What you need to know about Screening in Pregnancy

You'll be offered some screening tests during pregnancy to check for 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.

Pregnancy Screening tests are NOT PERFECT:


It is important to recognise that a screening test is not a diagnostic test. This means that a condition may be suspected but is not always confirmed, you may therefore be offered additional testing or procedures following screening.


Screening tests are used to find people at higher chance of a health problem.

This means they can get earlier, potentially more effective, treatment or make informed decisions about their health.


Some people will be told that they or their baby have a higher chance of having a health condition when in fact they do not have the condition. Also, a few people will be told that they or their baby have a lower chance of having a health condition when in fact they do have the condition.


What do Pregnancy Screening Tests Involve?


The screening tests offered during pregnancy in England are either ultrasound scans or blood tests, or a combination of both.
