- Study of GW-NIPT in 2335 frozen plasma samples to detect GW chromosomal anomalies including common trisomies, SCAs, RAAs, and partial deletions and duplications.
- “Genome-wide screening analysis including known mosaics correctly classified 27/28 RAAs and 20/27 partial deletions/duplications with a specificity of 99.80% for both anomalies, and an overall genome-wide specificity for all anomalies of 99.34%.”
- ”With an overall genome-wide clinical specificity for any anomaly of 99.34%, this genome-wide screen allows for detection of a broad range of chromosomal anomalies while retaining a clinical specificity far superior to the ~5% false-positive rate of serum screening.”
