Amniocentesis is recommended as the first choice for pregnancy at the age of 35 and needs to be performed under the supervision of a doctor.
At 35 years of age when pregnancy is already at an advanced age, it is recommended that amniocentesis be the first choice due to the increased risk of developing fetal chromosomal abnormalities or structural developmental abnormalities, etc. Amniocentesis can clarify the presence or absence of chromosomal problems.
Non-invasive prenatal testing technology is also an option for 35-year-old pregnant women whose only risk factor is age and who cannot accept the risk of amniocentesis.
Non-invasive prenatal testing (NIPT) is a prenatal test that screens for only three types of aneuploid chromosomal disorders, trisomy 21, trisomy 18 and trisomy 13, and a positive result will still require a definitive diagnosis such as amniocentesis.
However, amniocentesis is preferred for pregnant women who have a combination of chromosomal abnormalities and whose fetus may be at risk for genetic disorders.
