NACE
The NACE test is a
non-invasive prenatal test. To perform the test, all that’s needed is a small
sample of blood just like for any other routine blood test.
The NACE test compares
foetal DNA with the mother’s DNA to detect abnormalities .During pregnancy, the
baby’s DNA mixes with mother’s blood DNA.
Now it possible to detect fetal DNA in the mother’s blood and screen genetic
data of the baby’s chromosomes.
This
patient had screening test for downs
syndrome,. She was very anxious and tearful when double marker test was done, the result came positive for downs syndrome .
This is an indication that the the baby maybe suffering from downs syndrome,
but not a confirmation. Downs syndrome is an abnormality of chromosome number
21, and those babies are mentally retarded, and may have other abnormalities
like cardiac problems as well. It is often very stressful for parents to
receive such a report . They need to undergo further tests like NACE or
Amniocentesis to confirm or rule out downs. NACE will further screen and is done to avoid
amniocentesis , but it is not diagnostic. Amniocentesis will be done to confirm
whether it is true downs or just a false alarm. If NACE test is also positive,
Amniocentesis should be performed directly , it is done by taking fluid around
baby and doing genetic test on that .We did NACE test instead of amniocentesis (
which is an invasive test with 1% risk of miscarriage ). The result is negative
and we are so relieved , along with the parents , as it was a precious
pregnancy achieved through IUI,after severe oligoasthenoteratospermia .
