Participants underwent NIPT at 11 to 13\u2009weeks gestation by sequencing. Resampling was recommended for both positive and testing failure cases. For NIPT positive results, participants were advised to have invasive testing. Clinical outcomes were obtained by telephone interview.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In total of 579 cases, testing failure rates after first sampling and resampling were 7.6% and 1.4%, respectively. Twelve positive results were reported by NIPT. But only one true positive was confirmed, giving a PPV of 8%. A total of 576 cases completed the follow\u2010up (including 533 NIPT negative, 12 positive, and 31 testing failure) and three cases lost follow\u2010up. Among the 536 cases with NIPT negative results, 504 (94.0%) resulted in live\u2010birth and 29 (5.4%) resulted in miscarriage or stillbirths.
