any mothers during their 16-18 weeks pregnancy carry out this test?
it's a screen test to indicate the risk of the baby affected with Down syndrome.

i read it's just to see if the risk is high or low and the cutting point is 1/270. anything greater than 1/270 is consider high risk.

if you're in the high risk category, this does not mean your baby is confirm a down syndrome. sometimes those with low risk also can have a Down baby.

pls share on this topic.

thanks
