ABSTRACT:
There is disclosed a method for antenatal screening for an abnormality in a fetus using a bodily fluid, the fluid containing a marker which at one stage of gestation (stage A) the mean or median level) of the marker differs by less than 20% between pregnancies which are affected and unaffected by the abnormality and at another stage of gestation (stage B) differs by more than 50% between such affected and unaffected pregnancies, there being a period of at least 3 weeks between Stage A and Stage B and an apparatus for carrying out the method.
