Alan Adler, an expert on porphyrins, the types of colored compounds seen in
blood, chlorophyll, and many other natural products concluded that the blood is
real. In collaboration with John Heller, the conclusions that the blood is real
was published in the peer-reviewed scientific journal Applied Optics [19, (16)
1980]. The heme was converted into its parent porphyrin, and this was confirmed
with spectral analysis.
Baima Bollone also found both the heme porphyrin ring of blood and the globulin
in flakes of blood from Shroud samples, independently confirming the work of
Adler and Heller.
In addition, the x-ray-fluorescence spectra showed excess iron in blood areas,
as expected for blood. Microchemical tests for proteins were positive in blood
areas but not in any other parts of the Shroud.

Scientist-Journalist Philip Ball Nature, that most prestigious of scientific journals, that once had bragging rights to claim that the Shroud was fake, responding to new, peer-reviewed studies that discredit the carbon 14 dating and show that the Shroud could be authentic. WHAT WE KNOW IN 2005
