Although diagnostic testing can (very slightly) increase the risk
, some parents decide to take the test for several reasons. There may be a specific reason why your baby could be at risk of being born with a defect and so parents want to know in advance so they can be prepared. Some disorders may require your baby to have special care after birth and so you will have time to make the necessary arrangements. You will also be able to prepare emotionally and will have time to learn about the specific disorder, which will make your life a bit easier when baby arrives. Knowing your baby’s condition in advance may also help your doctor prepare for the delivery and so your baby can be delivered as safely as possible.
If the tests turn up negative then you will have a major worry off your mind, although you should bear in mind that not all defects can be detected.
Many parents will feel that an increased risk of miscarriage is not a risk worth taking and would rather not take the test just for the sake of knowing. It depends on what makes you more nervous as a parent – a small increase in the risk of miscarriage or being unsure about your baby’s condition and health.
