Prenatal screening tests are broadly categorized into two main types:
1. Maternal Serum Screening Tests: This category includes the Combined First Trimester Screen (Dual Test), Triple Test, and Quadruple Test, which assess the risk of certain chromosomal abnormalities.
2. Cell-Free DNA (cfDNA) Testing (Non-invasive Prenatal Testing - NIPT): This advanced screening method analyzes fetal DNA fragments present in the mother's blood to evaluate the risk of specific chromosomal conditions.
