Down syndrome test
The latest non-invasive Down syndrome test in unborn babies would greatly enhance detection rates if it’s available to all pregnant women.
What is Down Syndrome?
Children with Down syndrome tend to have an extra copy of chromosome 21. Down syndrome children suffer from physical abnormalities and intellectual impairment. There is no cure for this chromosomal disorder.
Down Syndrome Test:
Scientists at Curtin University in Perth have discovered the new screening Down syndrome test can enhance detection rates and drastically reduce dependence on invasive diagnostic procedures, which could cause miscarriages.
The latest non-invasive Down syndrome test would have cut down on the number of invasive diagnostic procedures while miscarriages due to such procedures could have been reduced by 88% in women with high risk pregnancies
Researchers from Curtin University reviewed 32,478 WA pregnancies between January 2005 & December 2006.
The results showed that if all expectant mothers recognized as high-risk had opted for this new non-invasive testing procedure, up to 7 additional cases of Down syndrome may have been confirmed. The results show the new blood test gives better outcomes.
Currently, high risk pregnant women can opt for diagnostic testing like amniocentesis but it’s invasive and could cause miscarriage.
The test for Down syndrome is currently available in the private health sector in Australia. Eventually it will be available via the public health system.
