Non-Invasive Prenatal Testing: Advances, Applications, and Limitations in Prenatal Screening
Year: 2025
Type: article
Abstract: Non-invasive prenatal testing (NIPT) is a prenatal screening technology based on the analysis of cell-free fetal DNA (cfDNA) detected in maternal peripheral blood. It offers high detection efficiency for common chromosomal aneuploidies, such as trisomy 21 (T21), trisomy 18 (T18), trisomy 13 (T13), and sex chromosome aneuploidies (SCA). Additionally, NIPT has expanded to include the screening of subchromosomal microdeletions and microduplications, single-gene genetic diseases, and has even demonstrated certain diagnostic value for placental-derived complications during pregnancy. However, some of the problems it presents, such as technical limitations and ethical or psychological issues, cannot be overlooked. This article reviews the advancements and limitations of NIPT in prenatal screening.
