I'm sorry but I am skeptical. Show me the study. You wouldn't be the first person to misinterpret a scientific study. They are full of technical and scientific wording that most people don't understand. I know how hard it is to find studies on the internet that you happened to of chanced upon previously so I have been looking in Google "scholar" for any related studies. So far I have only found papers that mention how antigens are not destroyed by electric current but can be "moved" by it (directionally from one electrode and towards the other). Look at patent 4661224 as an example. Patent 5166063 talks about causing biomolecules (enzymes, antibodies, glycoproteins) to stick to an electrode so that they are immobilized, but not in the sense of losing their natural ability but rather losing their mobility in blood because of being stuck electrically to the electrode.
As far as so-and-so saying it hurts blood, Hulda Clark claimed that 30kHz killed all microbes but never ever gave any proof of it. All because someone with a web site says something, it doesn't make it so.
