This is a great post and the concluding algorithm makes a lot of sense . . . EXCEPT in a critical arena: timing. One of the real promises of cell-free DNA screening is how early it can be done. Having reliable screening results by 12 weeks (test at 10 weeks + 2 weeks for results) instead of 16-18 weeks for the quad screen is HUGE.

I think it will be within pretty short order that the bulleted concerns will be addressed and the algorithm will become cell-free DNA screening -> diagnostic testing.
