Prenatal Test - what is it and how the test is done
- Alpha-Fetoprotein (AFP) levels
- Chorionic Villus Sampling
Prenatal testing includes screening and diagnostic tests which provide valuable information about your baby's health. It involves blood tests or ultrasounds to assess the baby's health.
These tests test alpha-Fetoprotein (AFP) levels, chorionic villus sampling, and Amniocentesis. In the first trimester, a blood test and ultrasound are done to measure the size of the clear space in the tissue at the back of a baby's neck. During your second trimester, another blood test is called the quad screen. This test measures levels of four substances in your blood. Prenatal cell-free DNA screening provides information about a baby's sex and rhesus (Rh) blood type. These tests detect chromosomal aberrations and down syndrome identification.
The accuracy varies from test-test, and false positive or falsely negative results are possible.
Prenatal results provide information on whether the baby has a genetic defect. These can ease your anxiety during pregnancy about the baby's health.
Blood tests and ultrasounds pose limited risks for you and your baby. Invasive tests such as chorionic villus sampling or Amniocentesis carry a slight chance of pregnancy loss.
