Abstract
Blood samples held at either 4 degrees C or room temperature for 1 day had similar mean decreases in number of cytomegalovirus antigenemia-positive cells (52 to 55%) and similar false-negative test results (13 to 14%). After 2 days, samples held at 4 degrees C showed no further decline, whereas samples held at room temperature had a mean 81% decrease in positive cells, a 32% false-negative rate, and a more marked deterioration in cell morphology.
摘要
保存在4摄氏度或室温下1天的血样，巨细胞病毒抗原血症阳性细胞数量的平均降幅相似（52%至55%），假阴性检测结果也相似（13%至14%）。2天后，保存在4摄氏度的样本没有进一步下降，而保存在室温下的样本阳性细胞平均下降81%，假阴性率为32%，细胞形态恶化更明显。
