Are scans and tests in pregnancy compulsory?

Should I have the tests?

No, scans and tests are not compulsory however, you will be offered all tests and scans that are felt appropriate for you and your baby. Every test which is offered to you should be fully explained so that you know what the test is for, why it is being offered to you and what the results might show. Many of the tests offered are for conditions or situations which are only likely to affect a very few mums and babies but they may have serious consequences. If you are unsure whether to agree to a test or want to discuss it further do ask.

Should I have the tests?

You need to start thinking about which test you want to have, if any, almost as soon as you find out that you are pregnant. So the first or second time you see your GP or your midwife is the right time to ask them to talk through your options with you.

While many mothers are relieved that there are tests which will reassure them that their baby is healthy, others are unhappy about being tested. Remember that you are entirely within your rights to refuse tests (including ultrasound scans). Health professionals may sometimes be surprised by your decision, but it’s your body and your baby.

You might decide to go ahead with testing because:

• You need the reassurance that negative test results would bring
• You want to know if your baby has a problem so that you can prepare yourself for his or her arrival
• Your partner is very much in favour of tests
• You would certainly choose to terminate your pregnancy if the baby was found to have a serious health problem

You may decide at the very beginning of your pregnancy not to have any antenatal tests at all. Commons reasons for this include:

• You would never choose to terminate a pregnancy
• You are prepared to accept your baby just as he or she is
• You think the tests cause more anxiety than they provide reassurance
• Your partner is against testing
• You may already have a disabled child and believe that to test the baby you are carrying for abnormality and end the pregnancy if there is a problem would suggest to your other child that you find disability unacceptable

If you are disabled yourself or there is a family history of genetic or congenital conditions, before you get pregnant ask your GP to refer you to the clinical genetics unit at your regional referral centre. There you will be able to discuss the likelihood of your baby being affected with the same condition and how best to cope. If you are already pregnant, you should still ask to see a doctor, midwife or counsellor with specialist knowledge who can help you think about which tests are best for you.
