What is Down syndrome screening?
Down syndrome is a group of symptoms caused by abnormal chromosomes (inherited genetic material) that cause patients to have low intelligence, slow speech, and have problems using muscles.
Children with Down syndrome have 47 chromosomes (normal humans have 46). The most common cause is an extra chromosome on chromosome 21, which can occur in normal pregnancies.
“Currently, there are methods to screen for Down syndrome that can be tested in almost all pregnant mothers and can be done from the beginning of pregnancy.”
Is it necessary to test for Down syndrome? Why do we need to test?
Down syndrome is most common in pregnant women aged 35 and over, who have a 1 in 250 chance of having a baby with Down syndrome. The older you get, the higher your risk. However, pregnant women under 35 can still have babies with Down syndrome.

At what gestational age can Down syndrome be detected?
Down syndrome can be screened from the 10th week of pregnancy by testing pregnant women’s blood, called a “screening test.” However, if an abnormality is detected (a positive result from a blood test), the doctor will recommend confirming the results again by performing an amniocentesis to examine the chromosomes.
Such tests will help doctors and pregnant women plan for the care of a fetus with Down syndrome, and may also give pregnant women and couples the option of terminating a pregnancy.
What does a Down syndrome test tell you?
Down syndrome screening tells the chance and risk that the baby will have Down syndrome, allowing pregnant women to know in advance, allowing doctors and pregnant women to plan for treatment if the baby has Down syndrome.
