Abstract
This prospective, parallel, and blind study of 120 blood samples from immunocompromised patients examined the influence of delayed sample processing on cytomegalovirus antigenemia assay. Cytomegalovirus was detected in 49 samples (40.8%): 41 were processed within 2 to 4 h, and 40 were reprocessed the following day. Results were discrepant in 17 of the samples with the lowest positive cell counts. Differences between the two days did not reach statistical significance.
摘要
这项针对120份免疫功能低下患者血样的前瞻性、平行且盲法研究，考察了样本处理延迟对巨细胞病毒抗原血症检测的影响。在49份样本（40.8%）中检测到巨细胞病毒：41份在2至4小时内进行处理，40份在第二天重新处理。在阳性细胞计数最低的17份样本中，两天的结果存在差异。两天之间的差异未达到统计学显著性。
