What is the primary role of genetic testing in prenatal care?

• A. It identifies all possible birth defects
• B. It screens for potential genetic disorders
• C. It guarantees a healthy baby
• D. It replaces traditional ultrasound methods

Answer: (B)

The primary role of genetic testing in prenatal care is to screen for potential genetic disorders. This process allows healthcare providers to identify specific conditions that may affect the developing fetus, such as chromosomal abnormalities, single-gene disorders, or increased risk for certain genetic conditions. By screening for these disorders, healthcare providers and parents can make informed decisions regarding the pregnancy, potential interventions, or preparations for any necessary medical care after birth. While genetic testing does contribute to understanding some possible birth defects, it doesn't identify all possible defects, as many conditions may be unrelated to genetics or may not be detectable through current testing methods. Additionally, genetic testing does not guarantee a healthy baby; it can only provide information about the risk of certain genetic conditions. It also does not replace traditional ultrasound methods, which serve different purposes, such as assessing fetal development and anatomy. Therefore, the emphasis of prenatal genetic testing is primarily on screening for genetic disorders rather than providing a comprehensive diagnosis or a definitive outcome for the health of the baby.
