Couples who undergo preimplantation genetic testing can reduce the risk of having a child with chromosomal abnormalities. This technology allows for the screening of embryos for comprehensive genetic issues, thereby lowering the likelihood of conceiving a child with chromosomal abnormalities.

Symptoms of chromosomal abnormalities include discomfort during pregnancy and the risk of miscarriage. Postnatal symptoms may need to be discovered through prenatal tests.

The causes of chromosomal abnormalities may involve congenital heredity or acquired genetic mutations.

Pediatric chromosome tests can be used to diagnose various genetic disorders

At 17 weeks and 2 days pregnant, a prenatal ultrasound revealed that the fetus has reached the critical risk of chromosomal abnormalities, and it is recommended to undergo further examination and consult with a obstetrician.

Before undergoing the third-generation IVF, genetic material is tested on the embryo before transplantation to screen out healthy embryos for transfer, preventing the transmission of genetic diseases. The success rate ranges from 30-70%, depending on the hospital and region. Due to the screening before transplantation, all born infants are healthy.

Fetal chromosomal abnormalities may originate from both parents, and it is recommended to check both parents’ chromosomes before pregnancy. Maintaining a good lifestyle and increasing physical exercise can enhance physical resistance and immunity, which is helpful for the next pregnancy.

A 24-year-old with chromosomal abnormalities asks if she can get pregnant. It is advised to first check the uterus development and seek guidance and treatment from a professional doctor.

Trisomy 21 or neural tube defects, the recent prenatal test results indicate an abnormality. Further examination and maintaining a healthy lifestyle to enhance physical fitness are recommended.

When the screening result indicates chromosomal abnormalities, further confirmation can be obtained through non-invasive DNA testing, and attention should be paid to the child’s care.
