Product Description
A transabdominal ultrasound scan (full bladder) to measure the amount of fluid under the skin at the back of the fetal neck and a maternal blood sample for two blood markers (BhCG and PAPP-A). Together with maternal age, a probability is calculated for conditions such as Down Syndrome, Edward Syndrome and Patau Syndrome. If the probability is more than 1:150 then further testing like CVS, Amniocentesis or NIPT (Panorama) is offered.
