Executive Summary
There are wide variations in the methodology and markers used for antenatal screening in the UK for Down's syndrome, says a new UK study in the October 9 edition of The Lancet. The survey shows that antenatal screening with serum or ultrasound markers has increased over the past decade. However, the most common method offered by health authorities - the double test, AFP and total or free b-hCG - is not the best, says the study.
