The positive rate of NIPT for aneuploidy and CNV increases with maternal age and the number of positive cases in the four age groups. Binomial test were used to test associations between positive and negative cases in four age groups according to the single pregnancies and the differences were significant (mean≤ 24 ± SD≤ 24 = 1.9833 + 0.1281, p < 0.05; mean25–29 ± SD25–29 = 1.9867 + 0.11475, p < 0.05; mean30–34 ± SD30–34 = 1.9836 + 0.1271, p < 0.05; mean≥ 35 ± SD≥ 35 = 1.9757 + 0.15413, p < 0.05)
