"blood transfusion" is the process of transferring blood or blood-based products from one person into the circulatory system of another. blood transfusions can be life-saving in some situations, such as massive blood loss due to trauma, or can be used to replace blood lost during surgery. blood transfusions may also be used to treat a severe anaemia or thrombocytopenia caused by a blood disease. people suffering from hemophilia or sickle-cell disease may require frequent blood transfusions. early transfusions used whole blood, but modern medical practice is to use only components of the blood.

in the 1950s and 1960s, with newfound technology and gradual advances in medicine, pharmaceutical scientists found a way to take the factor ix from fresh frozen plasma (ffp) and give it to those with haemophilia b. though they found a way to treat the disease, the ffp contained only a small amount of factor ix, requiring large amounts of ffp to treat an actual bleeding episode, which resulted in the person requiring hospitalization. by the mid-1960s scientists found a way to get a larger amount of factor ix from ffp. by the late 1960s, pharmaceutical scientists found methods to separate the factor ix from plasma, which allows for neatly packaged bottles of factor ix concentrates. with the rise of factor ix concentrates it became easier for people to get treatment at home. although these advances in medicine had a significant positive impact on the treatment of haemophilia, there were many complications that came with it. by the early 1980s, scientists discovered that the medicines they had created were transferring blood-borne viruses, such as hepatitis, and hiv, the virus that causes aids. with the rise of these deadly viruses, scientists had to find improved methods for screening the blood products they received from donors.in 1982, scientists made a breakthrough in medicine and were able to clone factor ix gene. with this new development it decreased the risk of the many viruses. although the new factor was created, it wasn't available for haemophilia b patients till 1997.
