Do I need an empty stomach for noninvasive gene prenatal testing? 】

No, a regular diet will not have an impact on the test results. After the consultation, Ms. Liu considered it for a while and finally decided to do a non-invasive genetic prenatal test, although the type of examination was less than the amniocentesis, but at least there was no damage to the mother. After 3 weeks, the test results are low-risk, which means that there is a 99% certainty that the fetus has trisomy 21, trisomy 18, trisomy 13, Ms. Liu finally breathed a sigh of relief, through the follow-up obstetric examination, the baby is also normal.

The new non-invasive gene prenatal testing technology, as a more accurate screening method for Down syndrome, brings more options to expectant mothers in need.

Suitable groups include: pregnant women at critical risk of Down screening for Trisomy 21 or Trisomy 18, pregnant women with contraindications to invasive prenatal diagnosis (e.g., active infection, central placenta previa, threatened miscarriage, etc.), and pregnant women who have missed serological screening time. However, the type of chromosomal abnormalities currently diagnosed by this technology is still limited, and not all abnormalities of chromosomes can be found.

In short, due to the limitations of non-invasive genetic prenatal testing, it is necessary to carefully consider and consult carefully, and doctors will need to develop individualized prenatal screening and prenatal diagnosis programs according to the specific conditions of pregnant women.
