Down's syndrome : None that i know of but is there history of this genetic disorder?
Dr. James Ferguson

Screening / specific: There are some early screening tests like the maternal AFP determination or of a prenatal ultrasound that can be suggestive of ds but are not specific. The amniocentesis gathers cells that were shed by baby during pregnancy.Chromosome study of these cells is specific and dependable to confirm or exclude genetic disorders like ds.

Dr. Michael Amster
Specializes in Pediatrics
Physical and genetic: Down's syndrome is a genetic disorder having one too many of the 21 chromosome. Most are detected on the triple screen, followed by genetic testing on amniocentesis. However, there are physical signs to look for: a single palmar crease, very weak musculature, distinct facial features, and heart defects. There are other smaller signs. There will be developmental delay, and other health issues later.

Can I take a test to see if my fetus will have down syndrome?

2 doctor answers5 doctors weighed in
Dr. Craig Keathley
Obstetrics and Gynecology 24 years experience
Yes: The diagnostic test for Down syndrome is a fetal chromosome analysis or karyotype with fetal cells obtained by either chorionic villus sampling or amniocentesis. Both tests have complication risks. There are less invasive tests using ultrasound and blood tests that can suggest an elevated risk, but they only assess risks and are not diagnostic.
