Is a chromosome test necessary? Not everyone needs a chromosome test. If one of the couples has a family history of genetic disease, or has a history of unexplained spontaneous abortion, fetal malformation, stillbirth, stillbirth, embryonic cessation, or neonatal death, both couples should undergo a chromosome test. For older pregnant women, TORCH infection, or one of the couple\’s working environment is special (exposure to chemical, physical, radioactive substances, etc.), chorionic villus biopsy, amniocentesis and other examinations can be performed 2-3 months after pregnancy. Is a caesarean section really more dangerous than a vaginal birth?
