无创产前基因检测 （Non-invasive Prenatal Testing, NIPT）是通过检测母体血浆中的胎儿游离DNA，分析胎儿染色体非整倍体的新型检测技术，检测范围包括发病率较高的21-三体综合征（ 唐氏综合征 ）、18-三体综合征（ 爱德华氏综合征 ）、13-三体综合征（ 帕陶氏综合征 ...

Noninvasive prenatal testing (NIPT), sometimes called noninvasive prenatal screening (NIPS), is a method of determining the risk that the fetus will be born with certain genetic abnormalities. This testing analyzes small fragments of DNA that are circulating in a pregnant woman’s blood.

2022年10月12日 · What is the NIPT test? NIPT stands for noninvasive prenatal testing. It’s a screening test offered during pregnancy to see if the fetus is at risk for having a chromosomal disorder like Down syndrome (trisomy 21), trisomy 18 (Edwards syndrome) and trisomy 13 (Patau syndrome). The test can also determine the sex of the fetus.

Prenatal genetic screening (serum screening with or without nuchal translucency [NT] ultrasound or cell-free DNA screening) AND diagnostic testing (chorionic villus sampling [CVS] or amniocentesis) options should be discussed and offered to all pregnant patients regardless of age or risk of chromosomal abnormality.

Noninvasive prenatal testing, or NIPT, is a new option that uses a blood test to look for signs of Down syndrome, trisomy 13 and trisomy 18 by analyzing free fragments of DNA in the bloodstream. What is combined first trimester screening? This is available to pregnant people from weeks 11 through 13 of pregnancy.

Recently, the use of cell-free fetal DNA (cff-DNA) testing has been increasingly used in different countries, representing an opportunity for non-invasive prenatal screening of pregnant women. The aim of this narrative review is to describe the state of the art and the main strengths and limitations of this test for prenatal screening of fetal ...

NIPT is a non-invasive prenatal screening technique performed using next-generation sequencing (NGS) to sequence short cffDNA fragments in order to identify the genetic variants that represent chromosomal abnormalities.

2025年1月31日 · Noninvasive prenatal testing (NIPT) involves a simple blood screening that uses that DNA (it’s called cell-free DNA, or cfDNA) to analyze baby’s risk for a number of genetic disorders, including Down syndrome. But the tests themselves can produce false positives, especially for rarer conditions, which can cause unnecessary anxiety.

Non-Invasive Prenatal Testing, or NIPT, is a simple blood draw that screens for chromosomal abnormalities of a fetus while still in utero. When this screening was first performed it was used to determine the sex of a fetus, now it is also used to find aneuploidies in fetal DNA. [6] .
