A laboratory test done to confirm that blood from a donor and blood from the recipient are compatible.

Crossmatching
crossmatching
In crossmatching you don't actually mix the whole blood samples. You will mix the red blood cells of the donor with the plasma of the patient. So if the patient is Rhesus positive, it wont have antibodies in the plasma against the Rhesus factor on the red blood cells of the donor. So a crossmatch with either a negative or positive donor will be allright. So in this case, it is indeed possible.
As many as necessary to prevent bleeding associated with thrombocytopenia. In patients refractory to random donor platelet transfusions, platelet crossmatching may identify units providing better platelet count increases. If crossmatching is not effective, HLA matching of platelets may be necessary.

Blood charts are used to typically identify what blood type an individual has. The test is simple one; there's an anti-serum used to type the blood. If it clumps with Anti-A serum and not the B serum, you are a type A; if you clump with Anti-B serum and not A serum you are type B, if it clumps to Anti-A and B serums, then you are an AB, if doesn't clump to either Anti-A or B serum you are a type O.
While the idea of a cat and a dog donating blood to each other may seem plausible, in reality, it is not a common or straightforward practice. The compatibility of blood transfusions depends on various factors, and the immune systems of different species can react negatively to foreign blood. Here are some reasons why cross-species blood transfusions are generally not performed: Blood Types: Dogs and cats have different blood types, and compatibility issues can arise. Dogs, for example, have multiple blood types, while cats have the A, B, and AB blood types. Antibodies and Immune Response: The immune systems of animals can recognize foreign blood cells and trigger an immune response, leading to potentially severe reactions. Risk of Transfusion Reactions: Even within the same species, compatibility is crucial. Dogs and cats can have adverse reactions to mismatched blood, which is why blood typing and crossmatching are essential in veterinary transfusions. Specialized Veterinary Blood Banks: Some regions have established veterinary blood banks that collect and store blood products specifically for dogs or cats. These banks follow proper screening and testing protocols to ensure compatibility. If a cat or a dog requires a blood transfusion, it is typically performed with blood from a donor of the same species and, ideally, the same blood type. Veterinary professionals will conduct blood typing and crossmatching to minimize the risk of adverse reactions and ensure the well-being of the recipient. If you have concerns about your pet's health or the need for a blood transfusion, it's essential to consult with a veterinarian. They can assess the specific situation, determine the appropriate course of action, and identify suitable donors if needed.
The following tests are performed before the blood transfusion. 1. Hepatitus B 2. Hepatitus C 3. HIV 4. Treponima pallaidum (Symphillus) 5. Malarial Parasite 6. Creutz feldt Jacob disease or Mad cow disease
Blood is classified by type:Type AType BType ABType OBlood is also classified by rhesus (Rh) factor, which refers to a specific antigen in the blood. If your blood has the antigen, you're Rh positive. If your blood lacks the antigen, you're Rh negative.At one time, type O negative blood was considered the universal blood donor type. This implied that anyone - regardless of blood type - could receive type O negative blood without risking a transfusion reaction. However, even type O negative blood may have antibodies that cause serious reactions during a transfusion.Ideally, blood transfusions are done with donated blood that's an exact match for type and Rh factor. Even then, small samples of the recipient's and donor's blood are mixed to check compatibility in a process known as crossmatching. In an emergency, however, type O negative red blood cells may be given to anyone - especially if the situation is life-threatening or the matching blood type is in short supply.see link below
the nurse is responsible for insuring that the right unit of blood is to be administered to the right patient after typing and crossmatching by the lab. this is done by checking the lot, serial numbers, blood type, and expiration date with another nurse or qualified lab personnell. then the unit of blood has to be checked off with another nurse before administration. only registered nurses are allowed by law to administer blood products. before administering the unit, the nurse cannot obtain consent, the doctor has to get consent forms signed by the patient or a qualified representative of the patient, except in the cases of trauma or life saving situations if the patient is unable to make that decision, all pros and cons must also be explained by the doctor. all patients have the right to refuse transfusions. after consents are signed and the blood is checked by appropriate personnell, the nurse has to take a complete set of vital signs for a baseline. after starting the transfusion, the vital signs must be checked after 15 minutes, then 30 minutes from then, then at one hour. then vital signs must be checked every hour, according to hospital protocol. the vital signs are checked this often to monitor for a reaction to the blood. if a reaction occurs, then the transfusion must be stopped immediately and normal saline infused. blood can only be transfused with normal saline. some hospitals may give premedications before transfusion to reduce the chance of a reaction. a unit of whole blood (packed red blood cells) must be infused over 3.5-4 hours, but not over 4 hours from the time of the start of the transfusion.

Blood contains red blood cells. Red blood cells don't contain blood. Blood does not enter the red blood cell.
