Detection of trisomies 13, 18 and 21 using non-invasive prenatal testing
The clinical performance of non-invasive prenatal testing (NIPT) in the Down's syndrome screening based on 1,901 pregnant women in a Chinese hospital was investigated. This was a retrospective analysis of NIPT study in singleton pregnancy (n=1,901). The NIPT test is offered routinely as a prenatal screening test for common fetal aneuploidies, including trisomy 13 (T13), T18 and T21 to pregnant ...
متن کاملNoninvasive prenatal testing of trisomies 21 and 18 by massively parallel sequencing of maternal plasma DNA in twin pregnancies.
OBJECTIVE The objective of this study is to assess the performance of noninvasive prenatal testing for trisomies 21 and 18 on the basis of massively parallel sequencing of cell-free DNA from maternal plasma in twin pregnancies. METHOD A double-blind study was performed over 12 months. A total of 189 pregnant women carrying twins were recruited from seven hospitals. Maternal plasma DNA sequenc...
متن کاملRecommended practice for laboratory reporting of non‐invasive prenatal testing of trisomies 13, 18 and 21: a consensus opinion
OBJECTIVE Non-invasive prenatal testing (NIPT) for trisomies 13, 18 and 21 is used worldwide. Laboratory reports should provide clear, concise results with test limitations indicated, yet no national or local guidelines are currently available. Here, we aim to present minimum best practice guidelines. METHODS All laboratories registered in the three European quality assurance schemes for mole...
متن کاملNon-Invasive Prenatal Diagnosis in Twin Pregnancies: Current Status
The objective of this review is to assess the evidence which supports the use of non-invasive prenatal diagnosis (NIPD) in twin pregnancies. Through the years, we have witnessed the technological developments in non-invasive prenatal diagnosis attained new heights, but those studies were usually limited in singleton pregnancies. As we known, twin pregnancies are at higher risk in both aneuploid...
متن کاملClinical evaluation of the IONA test: a non‐invasive prenatal screening test for trisomies 21, 18 and 13
OBJECTIVE To evaluate the clinical accuracy of the IONA® test for aneuploidy screening. METHODS This was a multicenter blinded study in which plasma samples from pregnant women at increased risk of trisomy 21 underwent cell-free DNA analysis utilizing the IONA test. For each sample, the IONA software generated a likelihood ratio and a maternal age-adjusted probability risk score for trisomies...
