非侵入性产前筛查(NIPT)
我们正在翻译此内容。 Non-invasive prenatal screening test for Down’s syndrome and other serious genetic conditions
Safe Non-invasive with no risk of miscarriage.
Fast Provides results within 10-14days from sample receipt.
Accurate Greater than 99% detection of trisomy conditions and fetal sex determination.
Simple Uses a simple maternal blood sample.
Reliable quality The NIPT test is provided by high quality laboratory at Bumrungrad hospital using the IONA® test which is a regulated, CE marked test.
During pregnancy, the placenta leaks cell-free DNA which circulates in the maternal bloodstream. As a result, a maternal blood sample contains a mixture of fetal-placental and maternal circulating cell-free DNA. The NIPT test directly measures the amount of this cell-free DNA and can detect small changes in the DNA ratio between the maternal and fetal cell-free DNA when a fetal trisomy 21, 18 or 13 is present.
An example scenario showing the difference between the screening tests:
