Which tests are done in pregnancy to diagnose fetal abnormalities?

Hi,

Welcome to icliniq.com.

I do understand your concern.

Blood tests and scans that u should undergo include:

1. First trimester screening: Combined first-trimester screening, conducted between 11 to 14 weeks, involves a blood test (measuring Pregnancy-associated plasma protein-A and human chorionic gonadotropin levels) and a nuchal translucency ultrasound (measuring fluid at the back of the baby's neck). It estimates the risk of chromosomal abnormalities such as Down syndrome, Edwards syndrome, and Patau syndrome. The non-invasive cell-free DNA test (NIPT), performed as early as 10 weeks, analyzes fragments of fetal DNA in the mother's blood to screen for chromosomal abnormalities.

2. Second trimester screening: The quadruple screen, carried out around 15 to 20 weeks, measures levels of four substances to assess the risk of neural tube defects, chromosomal abnormalities, and other conditions. The anomaly scan, often done concurrently with the quadruple screen, examines the baby's anatomy for structural abnormalities.

3. Importance of prenatal testing: Prenatal testing yields valuable information about your unborn baby's health. Although not diagnostic, it can help in making informed decisions about the pregnancy, allowing for early intervention and planning for potential health issues. Prenatal testing also offers reassurance and peace of mind. However, the decision to undergo testing is personal and should be made in consultation with your healthcare provider. They can discuss the benefits and risks of each test, address concerns, and answer any questions you may have.

Remember, your doctor or midwife is your partner in ensuring a healthy pregnancy. Feel free to reach out with any further questions or concerns.

Thank you.
