Description

Trisomy 21 (Down syndrome), trisomy 18 (Edward's syndrome), and trisomy 13 (Patau's syndrome) are the three most prevalent autosomal aneuploid diseases. The incidence in newborns is 1/(600-800), 1/(3500-8000), and 1/(7000-20000). Intellectual disability, developmental delay, multiple deformities, reproductive disorders, etc. are common in children. Using a fetal chromosome aneuploidy (T21, T18, T13) detection kit (semiconductor sequencing), doctors can reliably identify these conditions in unborn children (trisomy 21, trisomy 18, and trisomy 13). Features of Fetal Aneuploidies (Trisomy 21, Trisomy 18, and Trisomy 13) Detection According to data from 190,277 NIPT clinical trials Once proven effective in clinical studies【1】: in total, NIPT has a sensitivity of 99.61% for T21, T18, and T13 and a specificity of 99.91%. Overall PPV was 89.74% and NPV was 99.99%. The concentration of fetal cell-free DNA is raised from 11.3% to 22.6% through novel experimental techniques.[1] Hu H, Liu H, Peng C, et al. Clinical Experience of Non-Invasive Prenatal Chromosomal Aneuploidy Testing in 190,277 Patient Samples[J]. Current Molecular Medicine, 2016, 16(8):759-766 Target Population of Fetal Aneuploidies (Trisomy 21, Trisomy 18 and Trisomy 13) Detection Women who are pregnant and whose fetal chromosomal aneuploidy risk value on a serological screen is between the high-risk cut-off value and 1/1000; Those who cannot undergo interventional prenatal diagnosis due to certain conditions (such as a history of abortion, a current infection with a chronic pathogen, a blood type other than Rh-positive, etc.);
