This actually the opposite of the truth. The Italian team actually used highly sensitive tests specifically for blood. They were actually MORE sensitive for old blood because it is more concentrated.
Adler et al didn't use tests specific for blood, but for components of blood. Nickell et al have shown that these tests show positives for the kind of paint Rogers admitted were on the shroud.
Re: Nickell
Nickell and his amateurs are NOT specialists in blood research as are Adler, Heller, and Cameron. His science advisor is a Geologist. Neither were the Italians. Your mere assertions do not make your claims true.
I am done with you.
