    en.wikipedia.org/wiki/Apheresis

    The yield is normally the equivalent of between six and ten random platelet concentrates. Quality control demands the platelets from apheresis be equal to or greater than 3.0 × 10 11 in number and have a pH of equal to or greater than 6.2 in 90% of the products tested and must be used within five days. Leukapheresis – leukocytes (white blood ...

    They circulate in the blood of mammals and are involved in hemostasis, leading to the formation of blood clots. Platelets release thread-like fibers to form these clots. The normal range (99% of population analyzed) for platelets is 150,000 to 450,000 per cubic millimeter. [6] If the number of platelets is too low, excessive bleeding can occur.

  5. Blood donation - Wikipedia

    en.wikipedia.org/wiki/Blood_donation

    The donor is also examined and asked specific questions about their medical history to make sure that donating blood is not hazardous to their health. The donor's hematocrit or hemoglobin level is tested to make sure that the loss of blood will not make them anemic, and this check is the most common reason that a donor is ineligible. [34]

    en.wikipedia.org/wiki/Complete_blood_count

    A complete blood count (CBC), also known as a full blood count (FBC), is a set of medical laboratory tests that provide information about the cells in a person's blood.The CBC indicates the counts of white blood cells, red blood cells and platelets, the concentration of hemoglobin, and the hematocrit (the volume percentage of red blood cells).

  7. Platelet - Wikipedia

    en.wikipedia.org/wiki/Platelet

    Platelets are either isolated from collected units of whole blood and pooled to make a therapeutic dose, or collected by platelet apheresis: blood is taken from the donor, passed through a device which removes the platelets, and the remainder is returned to the donor in a closed loop. The industry standard is for platelets to be tested for ...

  8. Whole blood - Wikipedia

    en.wikipedia.org/wiki/Whole_blood

    Platelets for transfusion can also be prepared from a unit of whole blood. Some blood banks have replaced this with platelets collected by plateletpheresis because whole blood platelets, sometimes called "random donor" platelets, must be pooled from multiple donors to get enough for an adult therapeutic dose. [20]

  9. Cord blood - Wikipedia

    en.wikipedia.org/wiki/Cord_blood

    Cord blood is composed of all the elements found in whole blood – red blood cells, white blood cells, plasma, platelets. [6] Compared to whole blood some differences in the blood composition exist, for example, cord blood contains higher numbers of natural killer cells, lower absolute number of T-cells and a higher proportion of immature T-cells.
