Abstract:
〈 b 〉 〈 i 〉 Introduction: 〈 /i 〉 〈 /b 〉 The sequencing-based noninvasive prenatal testing (NIPT) has been successfully integrated into clinical practice and facilitated the early detection of fetal chromosomal anomalies. However, a comprehensive reference material to evaluate and quality control NIPT services from different NIPT providers remains unavailable. 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 In this study, we established a set of NIPT reference material consisting of 192 simulated samples. Most of the potential factors influencing the accuracy of NIPT, such as fetal fraction, mosaicism, and interfering substances, were included in the reference material. We compared the performance of chromosomal abnormalities detection on 3 widely used sequencers (NextSeq 500, BGISEQ-500, and Ion Proton) based on the reference material. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 All 3 sequencers provided highly accurate and reliable results to samples with ≥3.5% fetal fractions and high percentage of mosaicism. 〈 b 〉 〈 i 〉 Conclusions: 〈 /i 〉 〈 /b 〉 The established reference material can serve as a universal standard quality control for the current and new-coming NIPT providers based on various sequencers.
