About this deal

Leukocyte reduction is the removal of white blood cells by filtration. Leukoreduced blood products are less likely to cause HLA alloimmunization (development of antibodies against specific blood types), febrile non-hemolytic transfusion reaction, cytomegalovirus infection, and platelet-transfusion refractoriness.

Another key aspect is handling of the blood from the donor to the patient. Also here PVC is unsurpassed. PVC blood bags ensure a shelf life of 42 days, which can be crucial for rare blood types. These blood bags have also improved cancer patients’ chances of survival by enabling doctors to separate platelets from blood during chemotherapy. Moreover, PVC blood bags allow for the highest sterilisation techniques and can even be frozen. DEHP alternatives for blood bags ready All donated blood should also be tested for the ABO blood group system and Rh blood group system to ensure that the patient is receiving compatible blood. [14] Your blood will be tested to determine your blood type and your Rh factor. Blood type is classified as A, B, AB or O. The Rh factor refers to the presence or absence of a specific antigen — a substance capable of stimulating an immune response — in the blood. You'll be classified as Rh positive or Rh negative, meaning you do or don't carry the antigen. This information is important because your blood type and Rh factor must be compatible with the blood type and Rh factor of the person receiving your blood.Collect the quantity of blood following the instructions indicated on the bag label. Monitor the blood being drawn;

After blood collection is over, collect the blood needed and stop the collection by fastening the blood collection tube; These are the disposable biomedical transparent flexible poly vinyl chloride(PVC) containers, designed to collect, process and store the whole blood and blood components.Delayed hemolytic reactions occur more than 24 hours after a transfusion. They usually occur within 28 days of a transfusion. They can be due to either a low level of antibodies present prior to the start of the transfusion, which are not detectable on pre-transfusion testing; or development of a new antibody against an antigen in the transfused blood. Therefore, delayed haemolytic reaction does not manifest until after 24 hours when enough antibodies are available to cause a reaction. The red blood cells are removed by macrophages from the blood circulation into liver and spleen to be destroyed, which leads to extravascular haemolysis. This process usually mediated by anti-Rh and anti-Kidd antibodies. However, this type of transfusion reaction is less severe when compared to acute haemolytic transfusion reaction. [31] A blood-collection program was initiated [ by whom?] in the US in 1940 and Edwin Cohn pioneered the process of blood fractionation. He worked out the techniques for isolating the serum albumin fraction of blood plasma, which is essential for maintaining the osmotic pressure in the blood vessels, preventing their collapse. Studies show that the main motivators to blood donation tend to be prosocial (e.g., altruism, selflessness, charity), while the main deterrents include fear, distrust, [10] [11] or perceived racial discrimination in historic contexts.

The plasma product is frozen and placed in a big freezer that is -20C/ -4F or colder, then it waits until the viral marker test results are entered in the blood bank computer.
