NT Screening vs. Amnio

Hi, I am 38 years old and 14 weeks pregnant with my 2nd child. I just had
the Nuchal translucency screening done and just found out my results are
within normal range. I understand the older we get, there is an increased
risk of genetic disorders. Are the miscarriage risks of an amnio that high?
I am a bit confused.

The risk of miscarriage with an amnio is somewhere in the
range of 1 in 100 to 1 in 200 depending on who's doing it. Whether
that's too high depends on your personal views.

I think there are some more recent data that put it more in the 1/200
- 1/400 range, but Ericka's the research lady around here!

Could be. I haven't really looked it up in a year
or so. I suspect there's still a lot of variation, though.
If I wanted an amnio, I'd look for someone with a lot of
experience and a good track record. I suspect that the
most skilled practitioners have significantly better odds.
hmmm.....
I did a quick Medline search. There's a June 2007
German study with 8 years of data, 20,460 subjects, 11,017 controls
that found a 1 in 200 risk. A 2004 meta-analysis found a
0.6 percent procedure-related risk of fetal loss. A 2006
study showed a 0.86 percent procedure related risk. There
was a Turkish study that showed no additional risk. I didn't
do an extensive search, though.
