COLLECTION OF BLOOD
Prior to blood donation, the donors undergo a screening process which consists of confidential medical examinations including medical history, hemoglobin examination, blood pressure, weight, pulse and temperature check. Then, a small amount of blood sample is taken for grouping, check for infectious diseases and cross matching with the patient’s blood to identify compatible blood products for blood transfusions. Single Donor Apheresis Platelet (SDP) are prepared by connecting the donor to a machine and selectively collecting the platelet and returning the remaining blood components back to the donor. All our materials used in blood donation are strictly sterile and disposable.
General qualification for blood donation: general good health, weigh should be at least 50 kg, with no history of hepatitis and no risk of HIV. Donors’ age > 18 year, good general appearance.

STORAGE OF BLOOD
We store Whole Blood, Packed red blood cells, Fresh Frozen Plasma (FFP) and platelet concentrate gathered via blood donation from family members, friends, and volunteer donors.
The collected Whole Blood is spun in a centrifuge to separate it into different components. It is stored at 2-6°C, and preserved for 35 days with CPDA-1.
The packed Red Blood Cells (RBC) are refrigerated with an anti-coagulant solution (CPDA-1) to extend shelf life to 35 days.
The less dense blood plasma is made into Fresh Frozen Plasma (FFP) by freezing it promptly within 6 hours of collection; it is stored at –30°C or colder for one year. The platelets are stored in an incubator at 20-24°C temperature with agitation, and have a shelf life of five days. Since they are stored at room temperature, they are at high risk for growing bacteria. So, we are routinely doing quality checks which include blood count, pH and culture.
