Abstract
Background: Non-invasive prenatal testing (NIPT), also known as cell-free DNA testing and non-invasive prenatal screening (NIPS), is an important addition to the range of screening tests for fetal chromosomal abnormalities. For trisomy 21 in particular, NIPT is superior to other screening modalities. However, NIPT has limitations and complexities that requesting clinicians and their patients should understand.
Objective: This review article will briefly describe the technical basis of NIPT assays and compare the performance characteristics of NIPT with existing screening tests. The clinical use of NIPT will also be discussed.
Discussion: NIPT is now an established option for antenatal screening for trisomy 21, 18, 13 and other selected chromosomal abnormalities. If used appropriately, it increases the detection rate for fetal chromosomal abnormalities, while decreasing the number of invasive tests required. An understanding of the scientific basis of NIPT, and the appropriate clinical use and limitations, will enable medical practitioners to provide optimal antenatal screening.
期刊介绍：
The Australian Journal of General Practice (AJGP) aims to provide relevant, evidence-based, clearly articulated information to Australian GPs to assist them in providing the highest quality patient care, applicable to the varied geographic and social contexts in which GPs work and to all GP roles as clinician, researcher, educator, practice team member and opinion leader. All articles are subject to a peer-review process before they are accepted for publication. The journal is indexed in MEDLINE, Index Medicus and Science Citation Index Expanded.
