The department deals with the collection of blood components, platelets, apheresis by volunteer donors. In the Transfusion Medicine Institute of the FBIH, apherical procedures have been actively underway for the last twenty years.

Since the 1980s platelets have been collected from volunteers by the platelet pharynx method. The platelet thrombocytopenia is 400 to 500 platelet counts per year.

In addition to donor apheresis at the hemopharynx department, procedures for separating hematopoietic maternal peripheral blood in children and adults are also performed. There is ongoing work on the training of middle and high medical staff, and training for the application of the latest technology.

    Platelets (blood vessels) are small blood elements needed to stop bleeding.
How many platelets are there and where they are produced?
    The normal platelet count is 150000 to 450000 in a milliliter of blood. Platelets are created in the bone marrow. The life span of platelets is about a week later, after which they are disrupted and disappear from the circulation.
When are the platelet transfusions are applied?
    Platelet transfusion is applied to those patients whose platelet count is so much reduced that it is insufficient to prevent bleeding, which can also be life threatening. Concentrated platelets obtained with platelets are immediately given to a patient who has a risk of bleeding and only one dose is sufficient to save life. So prepared platelets can stay up to 5 days.
How do we get platelets that need to be given to patients?
    Platelets can be prepared from each blood unit obtained from volunteers. Meanwhile, the amount of platelet received is small and it is necessary for several people to have blood (four to eight) to prepare platelets for one patient. Thrombocytes can also be prepared by a method called platelet phereas. Then, the amount of platelet infusion from a single patient is a therapeutic dose for a patient.
What is thrombocitafereza?
    Thrombocytopheresis is the process of separating and collecting platelets from peripheral blood while simultaneously killing all other blood components, in a device called a blood vessel separator.
Is Plateletic Therapy Safe?
    Plateletic therapy is safe. The number of platelets separated from the blood donor is small compared to the total number of platelets in the blood and does not endanger the normal functioning of the organism and is restored for 48 hours. There is no risk of getting blood-borne diseases because it, because the set for platelets and all other accessories are used in a disposable procedure.
Who can be a platelet donor?
    A platelet donor can be any healthy person aged 18 to 60 years. After performing a medical examination and obtaining all the necessary information, blood samples are taken for necessary analyzes (blood collection, blood test, and testing for diseases that can be transmitted through blood -HIV, type B, C and syphilis ). Only after receiving satisfactory results of the test, the procedures will take place.
How often can you donate platelets?
    Platelets can be donated every month, or 12 times a year.
