It has been drawn to my attention (by my single reader) that it is a cruel, cruel thing to have left the blog un-updated at such a place in the plot. What were the results of the Nuchal Translucency scan? Did anyone get eaten by the Smilodon?! As Darwintoo: Stormageddon (Stormy or StormyD for short) is showing you in her pic below, all is thumbs up! Here is some updatey goodness for you!

Apparently, neck folds are wonderful diagnostic tools. Between 11weeks and 13weeks 6days, the fluid between the folds in the foetus' neck can be measured in a Nuchal Translucency Scan. These measurements are correlated with maternal blood to give a probability ratio for the risk of Trisomy (a third copy of) in chromosome 13, 18 or 21.
