The blood on the shroud is real male blood consistent with someone who went through great stress and trauma (beaten, tortured, and crucified), also consistent with Jesus’ accounts of crucifixion in the bible.
Even though the shroud has DNA from all over the world, the strongest genetic signals come from the Middle East and the Caucasus, not far from where Jesus was buried.
The burial is consistent with ancient Jewish burial customs (cave tombs, attitude of the body, and types of burial clothes).
The man in the shroud had no broken bones, just like stated in the bible that Jesus’ bones were not broken.
AB blood type is very rare and both the shroud of turin and the Sudarium of Oviedo have the same blood type. Both men died by crucifixion, but both men also had a Jewish burial. (unusual for crucifixion deaths) (more than 20 points of correlations; usual is 8-10).
Many people all around the world have their DNA on the shroud, as well as plant DNA from all over the world, so there's really not way to be sure of where it originated.
There are over 40 so-called burial clothes for Jesus of different textures and patterns.
Historian Antonio Lombatti claims the shroud was made 1,300 years after Jesus’ crucifixion and originated in Turkey.
Carbon texting at Oxford in 1988 dated the year 1260-1390.
The Shroud of Turin is made of a single textile woven in a complex twill pattern, a type of cloth not known to have been available in the region until medieval times
I am completely undecided on whether the shroud of turin is real or not. There as much evidence that points to authenticity of it as there is that points to prove it’s fake.
