As blood donations are provided on a voluntary non-remunerated basis, blood donors should be treated as user-friendly as possible. Delays and waiting times within blood collection sites (donor centers) should thus be kept at acceptable levels. Waiting times are not incorporated directly other than by practical experience. A more rigorous approach is required. An analytic waiting time computatio...

As part of the AACR Annual Meeting Methods Workshop "Sample Collection, Processing, and Storage for Large-Scale Studies: Biorepositories to Support Cancer Research," blood specimen collection, processing, storage, and dissemination issues were discussed. Whole blood and blood fractions comprise a major portion of biospecimen collections for population-based studies. Although procedures for coll...

Human placental blood (PB) is increasingly used as a source of hematopoietic stem cells for transplantation. Since the first successful transplant in 1988, more than 50 pediatric patients have been engrafted by means of PB collected at the birth of full-term newborns.’ and large PB banking programs are arising both in the United States and in Europe.’ In this regard, concern has been raised abo...

BACKGROUND AND OBJECTIVES We investigated the mixing capacity of two whole blood (WB) collection mixers. MATERIALS AND METHODS WB was simulated by using a 25% glycerol solution warmed to 35 degrees C. Citrate-phosphate-dextrose (CPD) anticoagulant of a collection system was stained with toluidine blue, and simulated WB was added at 30, 60 or 90 ml/min, respectively (n = 3 per flow speed). The...
