Screening tests are offered to all pregnant women to assess the chance of you or your baby having a health issue.
They don't provide a definite diagnosis, but help you and your midwife decide whether you need further tests to make a diagnosis.
Your pregnancy, your choice
It's important that you understand the purpose and possible results of the screening tests before you decide whether or not to have them.
You may choose not to be screened because you don’t want to know whether your baby has a health issue. You may choose to be screened so you can get support earlier and make decisions for you and your baby. For example, to prepare or plan treatment for after your baby's born.
You can discuss all screening tests with your midwife.
What tests will I be offered during my pregnancy?
During your pregnancy you'll be offered:
These are used to test for:
- blood count, blood group and Rhesus status (positive or negative)
- sickle cell and thalassaemia
- infectious diseases (hepatitis B, syphilis and HIV)
- Down’s syndrome
- fetal anomalies
You'll also be offered diagnostic tests if any conditions are suspected.
When will I have these tests?
Some pregnancy screening tests should take place as early as possible in pregnancy, ideally by 10 weeks, but can be done later on if necessary. However, some other tests can only be done at a certain time during pregnancy (for example screening for Down’s syndrome).
Pregnancy screening choices in Scotland will be changing in Summer 2020. Check for the most up-to-date information.
What tests will I be offered after birth?
Towards the end of your pregnancy your midwife will talk to you about newborn screening.
Pregnancy screening leaflet
NHS Health Scotland has produced a leaflet explaining pregnancy screening in Scotland, why it's offered and what happens next if the test finds that your baby might have a condition or disorder.
This leaflet is available in English and other languages.
