The sensitivity of individual and pooled examination strategies at the level of the pools.

A pool of 10 individual samples is defined positive if either at least one egg is found following a pooled examination strategy or the mean fecal egg counts of the corresponding individual samples is non-zero.

由10份单一样本组成的混合样本，若满足以下任一条件，则被判定为阳性：其一，采用混合检测策略可检出至少一枚虫卵；其二，对应单一样本的平均粪便虫卵计数不为零。
