At Stanford Blood Center, we collect a combination of blood products ( red blood cells, platelets, plasma ) using different procedures and equipment. For the scope of this article, we ’ ll stress on two types of crimson lineage cellular telephone donations : one unit and doubly unit .
Single-unit, or what we refer to as whole blood donations, are the most common type of contribution at SBC and can be made up to six times per class. Each unharmed lineage contribution, after it has been processed in the lab, results in a unit each of red blood cells, frigid plasma, and white rake cell concentrates ( cryoprecipitate ). Separating the products allows us to provide hospitals with what patients need more specifically .
During a double red rake cellular telephone ( DRBC ) contribution, we specifically collect the lineage ’ s red cell component through an automatize machine, called the Alyx. The target book, once attained through collection, is divided into two processed units of crimson lineage cells. Because of the extra red cell loss, this procedure can only be done three times per year .
then, from a blood center ’ second perspective, which contribution type is preferred ? here at SBC, it depends on several factors :
• The contiguous necessitate of our armory

• The donor ’ s blood character
• The donor ’ south preferred contribution frequency
• The donor ’ sulfur interest in an automated contribution
Let ’ s explain in more detail. On the day of your travel to, our collections staff may ask you to consider a sealed contribution type depending on the beginning fastball above : our inventory. What type of rake do we need that day to meet the needs of patients at the hospitals we serve ? Would drawing a double unit of measurement be more effective in meeting the immediate demand ? Another consideration is blood type. Types O, A, and B are more common among the general population and, consequently, these types are used more much for transfusions. Processing two units from one procedure, particularly from O-negative donors ( the universal joint blood type ), is an efficient manner to keep our inventory at a healthy degree .
There are a couple early factors to look at when selecting the best contribution type for each individual donor. What is the donor ’ south preferred frequency of visits ? For those who visit a maximum of one or two times per year, a DRBC operation will allow us to collect the lapp number of units annually as donating twice adenine often.

For those interested in an automated DRBC donation, there are some things to consider. DRBC donations do take about 30 minutes longer and have more specific eligibility requirements. however, many donors report feeling well after an automatize contribution because of the fluid surrogate.
