Nuchal Translucency Screening

We're having nuchal translucency screening next week (on the 28th).  This is a test for Down syndrome and other chromosomal problems.  We're excited that we get to see the babies in an ultrasound again, but it is a bit nerve-wracking to think of some of the possibilities.  This seems to be a standard test that they do with twins (I think).  We are praying for regular results, so if you think about praying for the four of us between now and the 28th, we would surely appreciate it.  =)
