Here is an article from the world authoritative Nature scientific journal on prenatal parent-child DNA testing.

Summary of this article

Presents the latest research on prenatal paternity DNA testing published in the Nature scientific journal. Reliability and technological advances are explained from the perspective of a world authority.

The world’s most authoritative magazine is known as CELL or Nature, and we have found an interesting article from Nature Science Magazine.

This article states that approximately 40 sites are sufficient for prenatal paternity DNA testing at 7 weeks’ gestation when using STRs. It states that in 6% of cases, DNA could not be successfully extracted despite testing as early as seven weeks’ gestation. These figures are shocking. It is shocking that 47SNPs are sufficient for STRs, while some papers say that 5000 SNPs alone are needed.

More prenatal paternity tests at the Hiro Clinic than were presented in Nature.

59 STR + 94 SNP locations are examined.

HIRO Clinic accepts tests from 6 weeks of pregnancy, so please contact us.
