Vitalant | Red Cell Contamination in Platelets and Apheresis Granulocytes 6210 E. Oak Street P.O. Box 1867 Scottsdale, AZ 85252-1867 p 480.946.4201 f 480.675.5767 vitalant.org Red Cell Contamination in Platelets and Apheresis Granulocytes Vitalant prepares apheresis platelets by a method known to result in a component containing <2mL of red cells and inspects for red cell contamination present in all platelet components. If a platelet unit appears abnormally pink or red, Vitalant determines the volume of RBC present in each component. If more than 2 mL of RBC are present in the product, a sample tube labeled with the Donor Identification Number is supplied for the purpose of crossmatch with the recipient’s plasma. The current method to collect granulocytes is known to produce a product with more than 2 mL of RBC present. The hospital should have a policy that granulocyte collections should be ABO compatible and must be crossmatched with the recipient’s plasma. This is in compliance with: ▪ AABB Standards for Blood Banks and Transfusion Services, 32nd edition o Standard 5.15.5: The red cells in Apheresis Granulocytes and Platelets shall be ABO-compatible with the recipient’s plasma and be crossmatched as in Standard 5.16 unless the component is prepared by a method known to result in a component containing < 2 mL of red cells. The donor blood cells for the crossmatch may be obtained from a sample collected at the time of donation. ▪ College of American Pathologists (CAP) TRM. 40760 Granulocytes And/Or Platelets Crossmatch-Compatible o The red cells in granulocytes and/or platelets are crossmatch-compatible with the recipient’s plasma, except when the component contains less than 2 mL of donor red cells. Note: If a platelet unit appears abnormally pink or red, the contaminating red cell volume can be determined to assess whether crossmatching is required. 06/23/2020 .

  • Apheresis Donation This Quick Reference Guide Will Help You Identify the Best Donation for Your Unique Blood Type
    Apheresis Donation This quick reference guide will help you identify the best donation for your unique blood type. Donors now have the opportunity to make an apheresis (ay-fur-ee-sis) donation and donate just platelets, red cells, or plasma at blood drives. These individual components are vital for local patients in need. Platelets Control Bleeding Red Cells Deliver Oxygen Plasma transports blood cells & controls bleeding Donation Type Blood Types Requirements Donation Time A+, B+, O+ Over 75% of population has one of these blood types. Platelet Donation: Be healthy, weigh at least 114 lbs 2 hours cancer & surgery patients no aspirin for 48 hours Platelets only last five days after donation so the need is constant.

  • Cord Blood Stem Cell Transplantation
    LEUKEMIA LYMPHOMA MYELOMA FACTS Cord Blood Stem Cell Transplantation No. 2 in a series providing the latest information on blood cancers Highlights • Umbilical cord blood, like bone marrow and peripheral blood, is a rich source of stem cells for transplantation. There may be advantages for certain patients to have cord blood stem cell transplants instead of transplants with marrow or peripheral blood stem cells (PBSCs). • Stem cell transplants (peripheral blood, marrow or cord blood) may use the patient’s own stem cells (called “autologous transplants”) or use donor stem cells. Donor cells may come from either a related or unrelated matched donor (called an “allogeneic transplant”). Most transplant physicians would not want to use a baby’s own cord blood (“autologous transplant”) to treat his or her leukemia. This is because donor stem cells might better fight the leukemia than the child’s own stem cells. • Cord blood for transplantation is collected from the umbilical cord and placenta after a baby is delivered. Donated cord blood that meets requirements is frozen and stored at a cord blood bank for future use. • The American Academy of Pediatrics’s (AAP) policy statement (Pediatrics; 2007;119:165-170.) addresses public and private banking options available to parents. Among several recommendations, the report encourages parents to donate to public cord blood banks and discourages parents from using private cord blood banks for personal or family cord blood storage unless they have an older child with a condition that could benefit from transplantation. • The Stem Cell Therapeutic and Research Act of 2005 put several programs in place, including creation of the National Cord Blood Inventory (NCBI) for patients in need of transplantation.

Department of Oncology, Norwegian Radium Hospital, Oslo University Hospital; 2. Department of Paediatrics, Rigshospitalet, Copenhagen University Hospital; 3. Paediatric Haematology, Tampere University Hospital DOI: 10.17925/EOH.2010.04.0.24 Abstract High-dose chemotherapy with or without radiation followed by autologous haematopoietic stem cell transplantation (auto-HSCT) is now the standard of care for patients with chemosensitive relapsed aggressive non-Hodgkin’s lymphoma (NHL), chemosensitive relapsed Hodgkin’s disease (HD) and multiple myeloma (MM). Autologous haematopoietic stem cells also provide haematopoietic support after the administration of high-dose chemotherapy in relapsed NHL and MM. However, certain patients fail to mobilise a sufficient number of haematopoietic stem cells using standard cytokine-assisted mobilisation strategies. Recently, plerixafor, a novel bicyclam capable of specifically and reversibly binding to the CXCR4 receptor on haematopoietic stem cells, has been granted European approval, in combination with granulocyte colony-stimulating factor, for the enhancement of haematopoietic stem cell mobilisation to the peripheral blood for collection and subsequent autotransplantation in poorly mobilising lymphoma and MM patients. In this article the authors present their initial experience with plerixafor in a case series at their own institutions in Scandinavia. Keywords Autologous, stem cell, mobilisation, granulocyte colony-stimulating factor (G-CSF), autologous stem cell transplantation (auto-SCT), peripheral blood stem cells (PBSCs), chemotherapy, plerixafor Disclosure: The authors have no conflicts of interest to declare.

  • Form: Parental Consent for Blood Donation
    American Red Cross Biomedical Services Washington, DC 20006 Form: Parental Consent for Blood Donation Information This form must be completed by a parent or legal guardian. Parental permission is required for All donations by 16-year-olds All donations by any age student at high school blood drives in Utah Donations by 17-year-olds as required by state law or blood drive sponsor Before giving consent, please read the information on the back of this form and “A Student’s Guide to Blood Donation.” You should also read “Possible Use of Donor Information and Blood Samples in Medical Research” and the research study sheets for your state, which can be found at https://www.redcrossblood.org/donate-blood/how-to-donate/info-for- student-donors.html. If you do not have internet access, please call the Donor and Client Support Center at 1-866-236-3276 for relevant information regarding research studies. Before donating blood, your child will read “What You Must Know Before Giving Blood,” which describes the blood donation process. It explains the importance of accurate and honest answers to health history questions, what happens when a person gives blood, and tips for having a positive donation experience. It also explains why the Red Cross asks questions about sexual contact and identifies profiles of persons who should not donate (because of physical conditions, travel to certain countries, or high-risk behavior). “What You Must Know Before Giving Blood” contains explicit language defining “sexual contact.” A copy of this document is on file and available for viewing at your child’s school.
