CMV antibody prevalence and seroincidence in plateletpheresis donors

Journal of Clinical Apheresis, 2008
AbstractObjective: To determine the prevalence and seroincidence of CMV seropositivity in plateletpheresis donors of different ages and gender. Methods: CMV antibody serostatus, birthdate, and date of first and most recent donation between the years 1976 and 2006 were retrieved from 222 plateletpheresis donor records at the Johns Hopkins Hospital Donor

Cost effectiveness of quality assurance in plateletpheresis

Transfusion Science, 1999
A quality assurance system (QAS) is part of modern blood banking facilities. Quality control of single donor platelet (SDP) concentrates includes the determination of the platelet (PLT) yield and the white blood cell (WBC) contamination. Improvements in modern apheresis technology allow the collection of high PLT yields and leukoreduced products ...

Results with new software for plateletpheresis systems

Transfusion Science, 1994
New software for the cell separators A 201 and CS 3000 Plus have been developed by Baxter. Fresenius recently offered a single needle option for the AS 104 device. The results of separation are described with respect to total platelet yield, efficiency and cell contamination of the platelet concentrate (PC). Two software programs were evaluated in both

Disposable device for human plateletpheresis

The Journal of the Acoustical Society of America, 2018
Plateletpheresis is a crucial step for the blood donation and clinical diagnosis. Herein we demonstrate a method to conduct plateletpheresis using acoustofluidic technology in a disposable device that is fabricated solely by a plastic material with precise simulated modeling using low-cost technic.

Donor safety in triple plateletpheresis: results from the German and Austrian Plateletpheresis Study Group multicenter trial

Transfusion, 2012
BACKGROUND: The objective was to investigate potential risks for apheresis donors associated with a triple‐plateletpheresis (TP) program.STUDY DESIGN AND METHODS: Eleven hemapheresis centers randomly assigned 411 repeat donors (ratio, 1:1.2) to either double plateletpheresis (DP; 185 donors) or TP (226 donors) with a platelet (PLT) target content of at

Kinetics of CFU‐Mk after automated plateletpheresis

Vox Sanguinis, 2001
Background and ObjectivesPlatelet count, thrombopoetin (TPO) level and the compartment of megakaryocyte progenitor cells (CFU‐Mk) are major determinants in the regulation of thrombopoiesis. The aim of this study was to investigate the potential changes in the compartment of CFU‐Mk and their correlation with serum TPO levels and platelet count after ...

Change of coagulation parameters after double plateletpheresis

Transfusion and Apheresis Science, 2007
In the previous studies, some authors reported that automated apheresis leads to a hypercoagulable state. We tried to find out changes in coagulation parameters after double plateletpheresis in this study. Forty-five donors were recruited to the study, and coagulation parameters were assessed before and after double plateletpheresis.

Use of 'Split' Plateletpheresis Products for Alloimmunized Patients

Vox Sanguinis, 1994
AbstractSingle donor platelets obtained using the COBE Spectra were split into two halves and administered to alloimmunized patients with leukemia at two different points in time. The mean platelet yield was 6.83 times 1011(n = 63) with 56% of collections having yields of >6.0times1011(i.e.

Lowering the hemoglobin cutoff for female plateletpheresis donors

Transfusion, 1998
BACKGROUND: The standards of the American Association of Blood Banks describe a minimum hemoglobin level of 12.5 g per dL for apheresis donors. Until 1995, the authors' institution accepted occasional platelet donors with a lower minimum hemoglobin (11.5 g/dL), if accompanied by medical director approval.STUDY DESIGN: All donation records from a 6 ...

Plateletpheresis before redo CABG diminishes excessive blood transfusion

The Annals of Thoracic Surgery, 1996
Blood conservation remains an important element for patients undergoing cardiac operations with cardiopulmonary bypass. Preoperative platelet-rich plasma (PRP) harvest is an autologous blood conservation method. The efficacy of preoperative PRP harvest and post-cardiopulmonary bypass reinfusion on postoperative bleeding and need for postoperative blood
