@Kevin_P_Nichols @alexmeshkin With pooling and local test sites (so no 2-way individual shipping, which is a lot of that $40) the cost per sample goes way down. With low prevalence you can pool large groups. At some ratio it may well be cheaper than antigen.
@Kevin_P_Nichols@alexmeshkin，拥有联营和本地测试站点（因此没有双向个人运输，这是40美元的一大部分），每个样本的成本大大降低。流行率较低的情况下，你可以汇集大量人群。在某种程度上，它很可能比抗原便宜。
