Sentences with phrase «paternity testing labs»

Not exact matches

To probe whether the Toronto lab's test is prone to this problem when there is no Y chromosome DNA in a woman's blood, we submitted a sample from a woman who claimed to be seeking a prenatal paternity test, but in reality had never been pregnant.

The lab has also shifted from testing genetic markers known as short tandem repeats (STRs), which are standard in paternity testing, to recording single letter variants in the genetic code known as single nucleotide polymorphisms, or SNPs, which are rarely used for this purpose.

Although DNA testing is reliable, the paternity defendant can challenge the lab results as inaccurate.
