How was the Shroud of Turin carbon dated?

Many experts have stood by a 1988 carbon-14 dating of scraps of the cloth carried out by labs in Oxford, Zurich and Arizona that dated it from 1260 to 1390, which, of course, would rule out its used during the time of Christ. The cloth has been kept at the cathedral since 1578.

What DNA was found on the Shroud of Turin?

The only evidence that would conclusively authenticate the Shroud against naysayers and claims of forgery is Jesus DNA. It would be matched against the blood — type AB — found on the Shroud and considered rare.
