Shroud of Turin and the Resurrection of Jesus : Forensic Pathology
 

Old Blood Does Not Always Turn Black

This page is best understood by first reading the page, Forensic Pathology.

Some have argued that the blood could not be real because old blood always turns black with age. The bloodstains on the Shroud are red. But this argument is scientifically invalid. 

  • Ancient cloth, as it was manufactured in the Middle East during the first century, was starched on the loom and then washed in suds of the Soapwort plant. Ingredients of this natural soap are hemolytic, which would keep the blood red.
     

  • The blood on the Shroud is rich in bilirubin, a bile pigment produced when a human body is under severe traumatic stress. Bilirubin is bright red and stays red and will cause old blood to remain red in color.

The argument is moot. We know the blood is real.


  • Alan Adler, a professor of chemistry at Western Connecticut State University and an expert on porphyrins, the types of colored compounds seen in blood (chlorophyll and many other natural products) concluded that the blood is real.

  • Alder and John Heller, Professor of Life Sciences at the New England Institute, published their conclusions that the bloodstains were genuinein the peer-reviewed scientific journal Applied Optics [1980]. They reported spectral analysis confirmed that the heme was converted into its parent porphyrin.

  • Baima Bollone, working independently also found the heme porphyrin and globulin in flakes of blood from Shroud samples.

  • X-ray-fluorescence spectra showed excess iron in blood areas, as expected for blood.

  • Microchemical tests for proteins were positive in the  bloodstains but not in any other parts of the Shroud.
