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

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.

Moreprenatal paternity tests at the Hiro Clinicthan were presented in Nature.

59 STR + 94 SNP locations
are examined.

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