Pregnancy Guide

Checks for Abnormalities

You will be offered some screening tests during pregnancy to try to find any health problems that could affect you or your baby, such as infectious diseases, sickle cell and thalassaemia, Down’s syndrome, Edwards’ syndrome and Patau’s syndrome, or physical abnormalities.

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

What are screening tests?

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.

Screening tests are not perfect.  Some people will be told that they or their baby may have a higher chance of having a health problem when in fact they do not have a problem.  Also, a few people will be told that they or their baby have a low chance of having a health problem when in fact they do have a problem.

You may want to think carefully about whether or not you want to have these screening tests.
