Abstract
Dried blood spot (DBS) samples can be used for the detection of severe acute respiratory syndrome coronavirus 2 spike antibodies. DBS sampling is comparable to matched serum samples with a relative 98.1% sensitivity and 100% specificity. Thus, DBS sampling offers an alternative for population-wide serologic testing in the coronavirus pandemic.
摘要
干血斑（DBS）样本可用于检测严重急性呼吸综合征冠状病毒 2 刺突抗体。DBS 采样与匹配的血清样本具有可比性，相对灵敏度为 98.1%，特异性为 100%。因此，在冠状病毒大流行期间，DBS 采样为全人群血清学检测提供了一种替代方法。
