I searched for pet blood donation online and found there are several organizations. I don't have any numbers, put there are potentially hundreds in the USA. Looking at few sites, it appears there is no 'standard', this claim by one organization The only veterinary blood bank licensed by the USDA and the California Dept. of Food and Agriculture. We are inspected and approved for shipping by the Canadian Ministry of Agriculture. implies there are significant differences in quality across the available organizations.
So if I was considering allowing my pet to be a blood donor, what should I look for or consider before allowing them to participate?
If I have more than one emergency vet to choose from, what kind of questions should I ask about the source of their blood supply, while doing my pre-emergency research?
