Pregnancy Screening

What is Pregnancy Screening?

A range of screening tests are offered during pregnancy or just after birth to identify either mothers or babies who may have or be at higher risk of developing a health problem. This means they can get earlier, potentially more effective, treatment and make informed decisions about their health. Screening tests are not perfect. 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 screening tests involve?

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

What are the risks of screening tests?

Screening tests cannot harm you or the baby but it is important to consider carefully whether or not to have these tests. Some screening tests in pregnancy can lead to difficult decisions for you.

For example, screening tests for Down’s syndrome, Edwards’ syndrome or Patau’s syndrome can lead to difficult decisions about whether to have a diagnostic test, such as amniocentesis, that carries a chance of miscarriage. A diagnostic test tells you for certain whether you or your baby has the condition. If diagnostic tests show your baby has a condition, this can lead to a decision about whether you want to continue or end the pregnancy.

Having a further test will always be your decision, and healthcare professionals will support you whatever you decide. It’s up to you whether or not you choose to have screening tests in pregnancy.

Will screening tests give me a definite answer?

This depends what the screening tests are looking for.

Yes

Screening tests for HIV, hepatitis B and syphilis are very accurate, and will tell for certain whether you have these infections.

If the test is positive, you’ll be offered further tests and examinations by doctors to find out the treatment you need.

No

Screening for Down’s syndrome, Edwards’ syndrome and Patau’s syndrome cannot say for certain whether your baby has the condition. It tells you if your baby has a lower or higher chance of having the condition. If your baby has a higher chance of a condition, you’ll be offered a diagnostic test that gives a more definite “yes” or “no” answer.

Do I have to have screening?

No – it’s up to you whether you have a screening test. It’s a personal choice that only you can make. You can discuss each of the screening tests you’re offered with your midwife or doctor and decide whether or not it’s right for you.
