Pregnancy screening tests

By getting in touch with a midwife as soon as possible in your pregnancy, you will get all the expert help you need, including information and advice about your pregnancy screening options.

Screening tests are offered to all pregnant women. They are intended to show whether there is a chance your baby may have a condition.

Your midwife will explain all tests offered to you.

Rash in pregnancy

You must let your midwife, GP or obstetrician know immediately if you have a rash illness or have any contact with another person with a rash at any time during your pregnancy.

Please avoid any antenatal clinic, maternity setting or other pregnant women until you have been assessed.

Any illness where you have a fever and a rash may be due to you having an infectious disease which could harm your unborn baby. You may be offered tests to find out if you have been infected. The health professional that assesses you will need to know:

• how many weeks pregnant you are

• when the contact with someone with a rash illness was

• the date that you first developed or had contact with someone with a rash

• a description of the rash (is it a raised, bumpy rash or is it blisters filled with fluid?)

• what infections you have had in the past eg chicken pox, measles

• what vaccinations you have previously had.
