YP AnswersA blood bank is a medical facility where human blood may be collected, separated into constituent parts and stored. The blood is sourced from organizations that collect blood from donors or people who offer cash for blood collection. After the blood bank tests and separates the blood, it can then be sold to hospitals for use in blood transfusions, surgery and other medical procedures. Blood products are also commonly used for research purposes....Read More
YP AnswersBlood can either be donated to a charity organization or sold. In either case, the blood must first be drawn by a trained staff member. The process is generally the same in either case:
- First, the donor is screened for health and safety with a questionnaire. This involves several questions about the donor’s medical history as well as where they may have traveled recently. There are several diseases and disorders that may prevent someone from giving blood.
- Next, some of the donor’s vitals are checked. This usually includes getting a temperature reading (to check for signs of fever), testing blood pressure, and checking hemoglobin levels (the iron-carrying protein in red blood cells).
- The donation process itself varies depending on the method chosen. The most common and fastest method is a “whole blood” donation, in which one pint of blood is collected through an intravenous needle. In some cases, donors may be able to give through apheresis, in which blood is routed through a machine to separate it. The machine collects blood platelets, which are used in certain medical procedures, but returns the rest to the donor. Apheresis may take up to two hours, but may be less taxing on the donor.
- Finally, the donor is often given time to rest and eat a snack. The snack aims to replenish lost nutrients and fluids.
