Fig. 2From: Noninvasive prenatal testing of α-thalassemia and β-thalassemia through population-based parental haplotypingOutcomes of PBH-NIPT. We performed PBH-NIPT on 59 couples. Fifty-nine fetuses had 111 total alleles confirmed by invasive prenatal diagnosis, with 99.1% accuracy (95% CI, 95.1–100%). Fifty-two fetuses had both alleles detected for a total of 104 alleles; 7 fetuses had only one allele detectedBack to article page
