In emergency situations, doctors, patients often need a blood transfusion. Such an emergency measure as often happens when an injury causes a patient rapidly losing blood. Cross-matching, is a test carried out by doctors to determine whether the donated blood, the blood of the receptor, which is consistent urgently needed a blood transfusion. There are two ways to make correlations between the test: electronic and manual.

Cross Match mail: You just inject the blood of the donor and the recipient’s blood into a machine connected to a computer. If all the necessary components of blood are compatible, the computer will print a sheet that tells you it is safe to do a blood transfusion. The doctor can not with safety of blood transfusions. The electronic method is preferred because it is fast. This is an important factor in emergency situations when a patient has lost too much blood. The only negative point of this method is its reliability. Doctors question the safety margin. A team that never makes mistakes.

Serological Cross-matching: When is the electronic method available, serological cross-match is the second option. The procedure must do this manually, the physician or technician of blood in their hands to the test to verify the recipient’s blood represents the blood of the donor. Blood is drawn from the template. Blood plasma was extracted by the centrifuge method. The plasma is then injected with a syringe into a test tube with blood from donors. If agglutination occurs, it means that the patient’s plasma contains antibodies against the blood of the donor. If there are no lumps, then a match is in and the Blood Transfusion sure.

In an emergency, doctors, especially doctors in the emergency room is often no time to make a cross-match test. If no time, the doctor to the patient type O, Rh-blood for the patient. Type O, Rh-factor is a universal donor, and therefore it is safe to give to each patient. But Type O, Rh-factor is rare and not widely available. If this situation occurs, the physician should always be ready to take a decision by the infusion of the patient with blood unprecedented. This is a risky decision, but studies have shown that the benefits outweigh the risks. Therefore, a physician is entitled to take action in an emergency situation. If the patient loses blood faster, the better the chance of saving the patient an opportunity and with the same blood transfusion, rather than doing nothing
