Veterinary Blood Donation Quiz

The ideal blood volume to donate from a healthy donor is only 10% of their total blood volume.

Donors for horses should be tested for certain specific antigens, like Qa and Aa. They should also be negative for these antigens and their antibodies.

Donors for horses should be certified as 'donkey factor free' if their plasma is used to treat failure of passive transfer in donkeys or mules. This ensures the plasma doesn't contain antibodies that could harm the foal.

Donors for cats should be tested for both A and B blood types because cats need type-specific transfusions.

The ideal blood donor is a young, healthy animal that has never received a blood transfusion. They should be screened for various health indicators and potential pathogens.

Dogs should be screened for specific pathogens like Anaplasma, Babesia, Bartonella, Ehrlichia, Leishmania, and Mycoplasma. This helps prevent transmitting infections to the recipient dog.

Ideally, dog blood donors are DEA 1 negative, making them 'universal donors' as their blood can be given to most dogs.

A large blood donation, up to 20% of the donor's blood volume, can be tolerated by a healthy donor. However, this is considered the maximum donation volume.

A condition where the body's ability to carry oxygen is reduced due to a low red blood cell count.

The percentage of red blood cells in the blood.

A type of blood transfusion where only the red blood cells are given to the patient.

A type of blood transfusion where only the liquid component of blood is given to the patient.

The process of identifying the blood type of an animal.

Antigen found on the surface of red blood cells in dogs. The presence or absence of this antigen determines a dog's blood type.

The immune response that occurs when a dog with the DEA 1 negative blood type receives blood from a dog with the DEA 1 positive blood type.

A condition where the body's ability to produce blood clotting factors is impaired.

A type of blood incompatibility in cats where kittens receiving colostrum from a mother with a different blood type can suffer from hemolysis.

An additional red blood cell antigen found in most cats that can cause hemolytic transfusion reactions if a cat lacking the Mik antigen receives blood from a Mik antigen-positive donor.

A blood type system in horses with over 30 red blood cell factors, with the Ca antigen being particularly important.

A condition in foals where the blood type of the mare and foal differ, and the foal inherits the stallion's sensitizing red blood cell type, leading to hemolysis.

A negative blood type in dogs that allows dogs with this blood type to be universal donors.

A blood typing method that uses cards or tubes with specific antibodies that react with the patient's blood to determine their blood type.

A blood typing method that uses a strip with antibodies that react with the patient's blood to determine their blood type.

A situation where a patient's blood cells clump together due to an immune response.

A test that identifies the presence of antibodies in recipient plasma that react with donor red blood cells.

A test that identifies the presence of antibodies in recipient red blood cells that react with donor plasma.

A crossmatch grade indicating no agglutination (clumping) of red blood cells.

A crossmatch grade indicating a few large agglutinates (clumps) mixed with smaller clumps of red blood cells.

A test to identify autoagglutination in recipient blood, which can hinder the accuracy of crossmatch results.

Incompatibility between donor and recipient blood that can lead to serious reactions during transfusion.

Incompatibility between donor and recipient blood that can lead to a mild reaction during transfusion.

A type of crossmatch where the donor blood chosen is compatible by both major and minor crossmatch.

Dogs with DEA 1 negative blood are considered "universal donors" because they lack the DEA 1 antigen. This allows their blood to be safely transfused into most dogs without triggering a strong immune response.

Cats must be blood typed before transfusion because giving the wrong type can be fatal. This is due to the presence of A and B blood types, which can lead to a severe immune reaction when incompatible types are mixed.

A major crossmatch test involves mixing the donor's red blood cells with the recipient's plasma. This helps identify any antibodies in the recipient's plasma that could attack the donor's red blood cells during transfusion.

Crossmatching is a crucial test to assess blood compatibility before a transfusion. It helps detect antibodies in the recipient's or donor's plasma that could lead to a transfusion reaction.

In an emergency, when a dog's blood type is unknown, DEA 1-negative blood can be given as a universal donor. This is because most dogs don't have antibodies against the DEA 1 antigen, minimizing the risk of a transfusion reaction.

A minor crossmatch mixes donor plasma with recipient red blood cells. It aims to detect any antibodies in the donor's plasma that could potentially react with the recipient's blood cells.

While crossmatching helps assess compatibility, it doesn't eliminate the possibility of transfusion reactions. It also doesn't prevent future sensitization to antigens, which could cause problems in future transfusions.

Dogs that have received a transfusion within 4-5 days should be typed and crossmatched. This is because it takes time for the body to develop antibodies against antigens following a transfusion.

A blood product containing only red blood cells and a small amount of plasma, used to treat various anemias and reduce the risk of volume overload.

A blood product that is administered within 6 hours of donation, containing all coagulation factors, active platelets, and plasma proteins, suitable for acute hemorrhage and anemic patients with coagulopathy.

Whole blood that has been stored for more than 6 hours, lacking active platelets and some coagulation factors, used for acute hemorrhage in animals with coagulopathy or hypoproteinemia.

A method of using individual blood components instead of whole blood, minimizing the risk of antigen exposure and maximizing the number of patients treated per donation.

A type of blood product used to enhance red cell storage life to 42 days by preventing cell damage.
