Trisomy 18 can be detected before birth
It can be detected both before and after birth. Before birth they do an amniocentesis and count the amount of chromosome in the cells of the amniotic fluid (which is from the baby). After birth they draw blood to count the chromosomes. My baby was diagnosed at 4 days old, though some people didn't now about it until their child was many months old.
