"Although the filtration process is super. There is an
infinitesimal amount of goat DNA, fragments, small chaines
that do get transfused into the patient."
You already had two good answers from PGS and floblu. However, your question goes to the core of what makes people nervous about transgenics. In short, the concept of mixing the DNA's of animals into humans is a scary one.
The real question is how "infinitesimal" is that amount of DNA transference, if any, and can it down the line create problems for these patients. I do not know the exact answer to that but I recall that it had been discussed previously and it was "determined" to be really infinitessimal and of no consequences to humans... As I recall, the thinking was that you would get more such transferrence by simply drinking regular goat milk, or eating goat, than you would get from ATryn... Of course, this argument only goes so far because our digestive tracks are equipped to deal with such matters but transfusions bypass all these defense mecahnisms. Perhaps I am cluelesss here but that is my recollection and that used to be a mojor concern of mine regarding GTCB and it is still somewhat of a concern...
