N IS FOR NUCHAL SCAN

Little Treasures - - NEW­BORN DAYS -

“This is part of a screen­ing tool to de­ter­mine a woman’s chances of car­ry­ing a child with chro­mo­so­mal ab­nor­mal­i­ties,” says Wil­son, who notes the woman will also need a blood test. “The scan mea­sures the size of the grow­ing foe­tus but fo­cuses on the pres­ence of a nasal bone and the size of the nuchal fold be­hind the baby’s neck. The more fluid in the fold, the greater the risk of com­pli­ca­tions.” If the risk falls un­der 1 in 300, the fam­ily will be given the op­tion of fur­ther test­ing (see A is for Am­nio­cen­te­sis).
