الگوریتم Reflex DNA screening

The Reflex DNA test involves taking two blood samples in the 11th, 12th or 13th week of pregnancy. One sample is used straight away to carry out a Combined test while the other sample is retained and only used for a DNA test if this is indicated by the result of the Combined test.
