What is efts test?

This screening test will combine all the information below to tell you about the chance to have a baby with trisomy 21 and trisomy 18:

Your age at the time of birth

You have a higher chance for chromosome differences like trisomy 21 and trisomy 18 as you get older. If you got pregnant through in vitro fertilization, it is the age of the egg that is used. The egg may be your own or from a donor.

11-14 week (nuchal translucency) ultrasound result

The nuchal translucency (NT) refers to the pocket of fluid at the back of the baby's neck. This pocket of fluid is measured during the ultrasound. When there is more fluid than what we typically see, there is an increased chance for trisomy 21, trisomy 18 and other conditions.

Blood draw result

The blood test for eFTS will measure the amount of 3 or 4  chemicals made by your pregnancy.

Other information about you

Your health-care provider will ask you some questions about you that improve the accuracy of test. You will be asked about your racial identity, diabetes status, smoking history in the pregnancy, weight and whether the pregnancy happened through in vitro fertilization.

eFTS is an optional prenatal genetic screening test that can tell you the chance for having a baby with trisomy 21 (Down syndrome) or trisomy 18 (Edwards syndrome). WHEN IS eFTS DONE? eFTS is done in the first trimester of pregnancy, usually between 11 weeks 2 days to 13 weeks 3 days gestation.
