Non-invasive first trimester blood test reliably detects Down's syndrome

This sounds like  a good advance.

 

New research has found that routine screening using a non-invasive test that analyzes fetal DNA in a pregnant woman's blood can accurately detect Down's syndrome and other genetic fetal abnormalities in the first trimester. Published early online in Ultrasound in Obstetrics & Gynecology, the results suggest that the test is superior to currently available screening strategies and could reshape standards in prenatal testing.

 

Current screening for Down's syndrome, or trisomy 21, and other trisomy conditions includes a combined test done between the 11th and 13th weeks of pregnancy, which involves an ultrasound screen and a hormonal analysis of the pregnant woman's blood. Only chorionic villus sampling and amniocentesis can definitely detect or rule out fetal genetic abnormalities, but these are invasive to the pregnancy and carry a risk of miscarriage.
