Abstract:
1. A composition comprising total free genomic DNA that comprises free fetal genomic DNA and free maternal genomic DNA, wherein the percentage of free fetal genomic DNA in the total free genomic DNA of the composition is selected from the group consisting of: about 24-25% free fetal genomic DNA, about 25-35% free fetal genomic DNA, about 35-45% free fetal genomic DNA, about 45-55% free fetal genomic DNA, about 55-65% free fetal genomic DNA, about 65-75% free fetal genomic DNA, about 75-85% free fetal genomic DNA, about 85-90% free fetal genomic DNA, about 90-91% free fetal genomic DNA, about 91-92% free fetal genomic DNA, about 92-93% free fetal genomic DNA, about 93-94% free fetal genomic DNA, about 94-95% free fetal genomic DNA, about 95-96% free fetal genomic DNA, about 96-97% free fetal genomic DNA, about 97-98% free fetal genomic DNA, about 98-99% free fetal genomic DNA, and about 99-99.7% free fetal genomic DNA, and further wherein said composition is obtained from a sample from a pregnant female.
