LP16699-8   Erythrocyte
Erythrocytes or red blood cells (RBCs) are the cells in the circulation that carry oxygen to and remove carbon dioxide from the tissues throughout the body. They are produced in the bone marrow in response to erythropoietin where they transition through six stages over a seven day period. When they are released into the circulation, their nucleus has been extruded and they measure 6-8 microns in diameter. The lifespan of RBCs is about 120 days. When the RBC ages the cell membrane becomes less pliable and tears as they cell travels through the micro vessels of the body. The damaged RBCs are removed from the circulation by the spleen. Variations in number, shape and size of RBCs are indicative of many diseases and disorders. There are many factors that may lead to decreased numbers of RBCs including hemorrhage, hemolysis, iron or vitamin deficiency, marrow failure and more. Larger than normal RBCs may be indicative of liver disease while smaller than normal RBCs are seen in thalassemias and other anemias.(Mosby's manual of diagnostic and laboratory tests, Kathleen Deska Pagana; Timothy James Pagana, Elsevier St. Louis, Mo ©2010) Source: Regenstrief LOINC

LP281774-2   ^Stem cell product
Bone marrow or peripheral blood hematopoietic stem cells are collected for patients scheduled to undergo stem cell (bone marrow) transplantation. For autologous transplants, the patient donates his or her own cells. For allogeneic transplants, a healthy donor provides cells for a patient. Collected cells (harvested by aspiration from the marrow or by therapeutic apheresis from the blood after treatment of the donor with a stem cell mobilizing agent such filgrastim) are processed to concentrate the stem cells. Stem cells may be further processed in a variety of ways, depending upon the source and volume of stem cells and the diagnosis of the recipient. In selected cases, the concentrated stem cell preparation is processed to concentrate or eliminate cells found in the collection. A special chemical mixture is added to protect cells during freezing, and they are frozen and stored at temperatures below 80 degrees Celsius until thawed for infusion into the patient. Stem cell transplantation is used to replace diseased bone marrow, as in leukemia, or as an adjunctive measure for patients undergoing high-dose chemotherapy and/or radiotherapy. For some diagnoses, stem cell transplantation procedures are experimental. New York Blood Center, accessed 20081218. Source: Regenstrief Institute , Stem cell product
