Are the bloodstains on the Shroud from real blood?
Different scientists working independently conducted immunological, fluorescence and spectrographic tests, as well as Rh and ABO typing of blood antigens that prove it beyond reasonable doubt. And several experts in forensic medicine and blood chemistry conclude that the stains were formed by real human bleeding from real wounds on a real human body that came into direct contact with the cloth. Many of the stains have the distinctive forensic signature of clotting with red corpuscles about the edge of the clot and a clear yellowish halo of serum.
