What is Down Syndrome?
Down syndrome is the most common chromosome disorder that we know of. One out of every 700-900 babies born worldwide will have Down syndrome, although this number is lower in Australia. People with Down syndrome have:
- some characteristic physical features
- some health and development challenges
- some level of intellectual disability.
These characteristics will vary from one person to another. A screening test for Down syndrome can be carried out before a baby is born either in the first trimester via a combined blood test and ultrasound, or during the second trimester via a blood test. This is not 100% accurate. www.downsyndrome.org.au/what_is_down_syndrome.html
What does the test involve?
First trimester combined screening test
This test combines the results of a blood test and a Nuchal Translucency test (measures the babies neck) via ultrasound. These test will show the risk of your chance of having a baby with Down syndrome. It will not tell you if your baby has Down Syndrome.
Second Trimester tests
This blood test is carried out at 14-20 weeks and measures ‘markers’ in your blood. If either of these tests shows a chance of Down syndrome further diagnostics tests can be carried out. The decision to carry out further tests is up to you and your family after further discussion with your doctor and/ or midwife; genetic counselling may also be available.
