That was done many years ago - first by the forensic scientist that was on the 1978 team - and he wrote a book on it - I forget the type - I'd have to look it up but I think it's AB.
I've been following this since the early '60's - Believe me, there are a lot of skeptics - the kind that would, as Thoreau said "find fault with the morning red - if they ever got up early enough. And there are a lot a atheists and dedicated groups that will do everything they can to tear it apart - even if proven. They have a vested interest in maligning the Shroud.
For every negative there are 100 positives, evidence wise. the preponderance is on the 'true' side - however, Bottom line is that is can never be proven, beyond a shadow of a doubt to be the Shroud of Jesus.
But it has been proven to be a burial shroud of the time and the place with all the points of the Biblical Crucifixion and the all the correct forensic details of a crucified man, etc etc.
Thereafter, it is up to us each to believe or not to believe. And that may be how it should be.
Faith. It’s difficult.
Well, not really.
STURP did no DNA analysis....and the guy that wrote that book you're referring to went WAY off the reservation. Got in some trouble for it, too.
However, the blood HAS been typed as AB+ and is definitely human blood. We even know which blood was from when he was alive and which blood was post-mortum (i.e. the blood from the spear thrust in his anatomical right side).
I would venture to guess that any DNA analysis of the blood on the Shroud would yield no DNA map. Scientific analysis of Eucharistic miracles, from all over the world, yield the following results: blood type AB, tissue type heart muscle from the sinoatrial node region, DNA mapping = empty set. It is a strange result, but it reminds us that we are made in His image, therefore we have DNA, but there is no necessity that He would have needed any pre-image.
