复杂基质下，客服口头说的交叉反应不够，要看说明书是否明确人源和猪源抗原序列或重组蛋白来源、捕获与检测抗体表位、种属矩阵、裂解液兼容。重点验证标准曲线线性、LLOQ/LOD、加标回收、稀释线性、基质匹配和高剂量钩状效应。组织裂解还要验证去垢剂、蛋白酶抑制剂和脂类干扰，必要时用同型对照或外源内参。

可建立简单验收模板：文件清单包括说明书、COA、批次、运输温度、有效期；验证记录包括样本类型、重复数、CV、回收率、标曲拟合、质控检出；同时写清接受准则和异常处置。建议做两批试纸或预实验，至少覆盖低中高浓度及边界样本。验收不只看R²，还要看回算点偏差、平行样本一致性、冻融稳定性和不同稀释液表现，便于后续换批追溯。
