Possible po. Makikita po kasi ang nuchal fold thickness sa ordinary ultrasound, and increase in nuchal fold thickness can be a sign na may down syndrome si baby. Then irerequest ka for another ultrasound like CAS to confirm. Heto po ang possible causes. https://ph.theasianparent.com/bagay-na-dapat-malaman-tungkol-sa-down-syndrome
Hindi po ata mommy, ang alam ko po sa CAS ( congenital anomaly scan) na type ng ultrasound nadedetect kung may problem sa development ni baby
Pag CAS po mamsh nakikita.
