With advances in veterinary medicine, more complex surgical procedures are being performed on our beloved pets. Thus, there is an increased need for blood bank programs to supply life-saving blood components. In the past, Veterinarians had to use their own dogs, dogs owned by their staff, or even dogs borrowed from their clients as blood donors in the absence of animal blood banks.
Blood banks for animals depend on animal blood donors for their supply of blood products as human blood banks depend on human blood donors. Animal blood is donated to the specie it belongs. For example, dogs can receive only dog blood; it is similar to other animals as well. Canines also have blood types just like humans; they have eleven different blood groups. The most important dog blood type is the A1/A2 system. A dog can be considered a universal donor if he/ she has A negative blood type.
Although dogs rarely have isoantibodies against other blood types, it is still recommended that all recipients be cross matched prior to receiving a blood transfusion, especially dogs which have received a previous blood transfusion to make sure that your donor and recipient are compatible.
Cross-matching tests can either be major or minor. The donor’s red blood cells are mixed with serum from the recipient in a major cross match test. It is observed if a reaction occurs. There is a possibility that the recipient’s blood cells may attack donor cells and not accept them. Unless desperately needed, transfusion should not be done if there is a major cross-match incompatibility. The red cells of the recipient are compared with the donor’s serum in a minor cross-match test. Only parts of the donor’s blood can be given to the recipient, not the blood in its entirety, if there is a minor cross-match incompatibility.
Qualities for canine donors are: healthy, no history of metabolic or heart disease or seizures, lean body weight of greater than 50 kg, and 1-7 years of age. They should not be on any medication, except heartworm and parasite preventatives. Potential donors should have a good temperament, have been neutered and nulliparous, and have jugular veins that are easily visualized and palpated. They should also be current on vaccines. Greyhounds have been promoted as ideal blood donors because of their amenable disposition and high PCV.
After the canine’s blood type is determined and is acceptable, donors are tested to make sure their blood values are high enough and no infectious disease is present before blood is drawn as with human blood donors. CBC, biochemical profile, U/A, fecal exam, von Willebrand’s factor, is done as well as testing for Dirofilaria immiti, Ehrlichia canis, Babesia canis, B. gibsoni, Brucella canis (in intact or previously bred dogs), and Bartonella.
There is no preparation before going to the donation center and no fasting is required. Donor dogs are not sedated and the donation itself takes less than half an hour. The dog is welcomed in and lifted onto a table. Blood is taken from the jugular vein, which is a large vein in the neck. A small patch of hair on the neck is shaved to expose the skin right over the vein. The area is then swabbed with alcohol and a needle is inserted into the vein. Blood goes into the needle, through a tube, and then into the collection bag. After the blood is collected, pressure is applied to stop any bleeding and the donor is then lifted off the table. There might be a mild bruising at the site.
To replenish fluids and nutrients, water and food are given. Right after the donation, the dog’s system starts to replace the blood immediately by producing new red blood cells. As with human blood donors, it is advised that strenuous activities should be avoided for the next 24 hours after donating. A waiting period of at least two months is needed before the next blood donation. By that time, blood volume and red blood cell count is back to normal.
As soon as they have made their donation, animal donors are compensated with various gifts and treats. They may be rewarded with a tag that identifies him or her as a blood donor, edible rewards that may include dog biscuits, a jar of baby food, a can or a bag of dog food, brand new toys and cool donor bandanas.
After the collection, the different blood components - red cells, plasma, and platelets will be separated. Anemic recipients are given red cells. Plasma builds up blood volume, thus it is given to animals that are not making enough or are losing large amounts of protein. For those recipients whose platelets are depleted or dysfunctional, they are given platelet-rich plasma.
Now, there several animal blood banks that supply blood products to Veterinary hospitals. Fortunately, dog owners have a positive response to the plea for blood donations. Every year, the animal blood bank processes roughly 2,000 units of blood donated by dogs. The donated blood is then brought in to the bank at the Veterinary hospital and to the bank’s bloodmobile, which visits Veterinary clinics and kennel clubs.
Other regional blood banks rely entirely on the generous and caring people who enroll their pets in blood donor programs. These animal blood banks hold drives to find new volunteer donors and encourage them to donate just like the Red Cross and other health organizations do to acquire human blood donations.
If you think your dog could be a blood donor, you can check the location of regional blood banks or the list of Veterinary Hospitals and University Veterinary Medical Centers that manage their own blood donor/blood bank programs. Or you can contact the animal blood banks for dogs and cats nearest you, or ask your Veterinarian if there’s an animal blood donor program with a donation site in your area.
