Research: Two babies are miscarried for every three Down syndrome babies detected by amniocentesis and cvs

That's according to this report in the Telegraph (UK) that cites the findings of research recently published in the journal Down Syndrome Research and Practice. Here is an excerpt:

The losses are down to the invasive methods used to test for the condition, which affects approximately one in every 1,000 babies conceived, the researchers claim.

They also cast doubt on the advice and risk assessment given to the 6,000 women each year who are offered screening and subsequent testing to assess the health of their unborn baby.

If an expectant mother is deemed to be at risk of carrying a Down's baby following a blood test, she will then go on to undergo an amniocentesis and chorionic villus sampling (CVS) test, which involves inserting a fine needle through the abdomen to either withdraw amniotic fluid or take a tissue sample.

The NHS cites a miscarriage rate of between one and two per cent following the tests, but the researchers, from the charity Down's Syndrome Education International, point out that only the number of Down's babies terminated, miscarried or born are recorded, not the number of healthy babies lost.
