My markers (or quad screen was normal). Did they do the DNA testing on you??
it wasn't me, my Brothers wife. Quad screen is not really the same as markers, markers are something they can see on an ultrasound that resemble Down syndrome. There are several they look for, having one (in your case, an Echogenic bowel) is to uncommon and does not mean your child has DS. She didn't have a DNA test, she had a specialist do another Level II u/s and the bowel had cleared up by that time.
