"It seems remarkable that all five test for the same, rare blood type. But there is a problem: the A and B antigens are not unique to humans. Since the 1960s, biologists have known that bacteria cells also have A and B antigens on their surfaces. Hence, if a sample is contaminated with bacteria, even if it contains no blood at all, it could still show a type AB blood result in this test.

Yet, without anyone ever checking for bacteria as the explanation, the claim about the blood type is often repeated as miraculous."

They do check for Serratia, thats literally the FIRST thing they do

Dr. Kearse devised, for the first time ever, a set of control experiments. He obtained unconsecrated Communion wafers and processed them according to the same conditions described above. He left them in a dusty, dark corner for several days and then stored them in water at ambient temperature and humidity for seven to 10 days. Approximately 15 percent of the control wafers formed a gelatinous red substance on the surface, like the photos from the eucharistic miracle reports.

Microscopy, fluorescence, and molecular biology techniques showed the reddish substance to be fungus and bacteria. Again, this is a natural explanation that was not checked but easily could be. Dr. Kearse presents a variety of tests showing that blood can easily be distinguished from microorganisms. As before, genetic testing would ultimately confirm what the red substances are and whether they have a single origin.

They test for serratia

The other AB results are from cloths believed to have touched Jesus at the crucifixion (the relics): the Shroud of Turin (a burial garment), the Tunic of Argenteuil (a seamless robe), and the Sudarium of Oviedo (a face cloth).

Also, Sokolka went through electron microscopy, and serratia tests.

" Two independent university professors. Professor Maria Elżbieta Sobaniec-Łotowska and Professor Stanisław Sulkowski, both of the Department of Pathomorphology at the Medical University of Białystok, conducted independent analyses and reached the same conclusion — without consulting each other.

• The tissue is cardiac muscle. Both professors identified the substance as human cardiac muscle tissue (myocardium) based on multiple diagnostic features: segmentation and fragmentation of muscle fibers, communicating junctions characteristic of heart muscle, centrally positioned cellular nuclei, and contraction nodes.

• Electron microscopy confirmation. Electron microscope imaging revealed intact myofibril filaments and junction outlines — structures visible only at extreme magnification that are uniquely characteristic of cardiac muscle. This level of structural preservation in unpreserved tissue exposed to water is, by established science, impossible.

• No decomposition. The tissue showed no signs of autolysis (cellular self-destruction) — a process that begins within hours of tissue death and is accelerated by water exposure. The professors explicitly noted that a bacterial culture would deteriorate within a week under similar conditions, yet this tissue remained intact for months.

• Tissue fused with bread at fiber level. Microscopic examination showed that the cardiac tissue was intertwined with the bread fibers of the Host at a structural level — not sitting on the surface, but integrated into the substrate. The scientists stated this phenomenon could not be replicated or explained by any known natural process.

• Official Church confirmation. On October 14, 2009, the Metropolitan Curia of Białystok issued an official statement confirming the scientific findings and declaring that the event “does not contradict the faith of the Church, but rather confirms it.”

• Consistent with the global pattern. The identification of cardiac muscle tissue places Sokółka in a direct line with Lanciano (1970 analysis), Buenos Aires (2004 analysis), and Tixtla (2009–2012 analysis) — four independent scientific investigations across three centuries of miracles, all finding the same tissue type."
