Patient's question:
Just switched to the screening. How should I read the results of the screening?Doctor's answer:
Down syndrome, also known as "Down syndrome" or "trisomy 21," refers to the change of chromosome 21 from the normal two copies to three copies. It is a disease caused by a multi-gene mutation of congenital chromosomal abnormalities and is one of the most common congenital birth defects. If your urine screening value is greater than 1,270 (the normal value is 1,700), it is recommended to perform a thorough abnormal clearance test and amniocentesis if a high-risk result reappears during the mid-pregnancy Down syndrome screening.
