Objective: To assess the association between the time fromumbilical cord blood collection until processing and the quality of the sample. Methods: Umbilical cord blood samples collected duringthe third stage of labor were placed in temperature-controlled boxesfor the transport of biological material and sent to an umbilical cordblood bank, where the number of nucleated cells, viable cells andCD34+ cells were counted, and samples were additionally testedfor contamination at the following time intervals: up to 24 hours,up to 48 hours and up to 72 hours following sampling. Data wereanalyzed using the multivariate analysis of variance (MANOVA) andcompared using McNemar’s χ2 test. Significance was defined at p< 0.05. Results: Means and medians of the number of nucleatedcells, viable cells and CD34+ cells decreased significantly (p |
