货期上优先选有稳定库存和按批次发货记录的供应商，下单前让其提供近期批次LOD、交叉反应表、适用基质和运输温控方案。孔雀石绿/结晶紫初筛如果只做半定量，国产成熟试剂通常货期更短、补货方便；进口可留作确证复核或高干扰批次验证。建议签货期承诺：每批到货附出厂检验或质检报告，允许留样，并在到货后连续做3批阴性、低中阳性平行测试，避免只看宣传灵敏度。

技术上先确认试剂盒目标物是孔雀石绿还是隐色孔雀石绿、是否兼顾结晶紫或隐色结晶紫，以及水产虾蟹色素、畜禽脂肪基质适配性。是否需要样本前处理小柱，应以说明书SOP为准：若要求净化或萃取，就同步采购配套小柱并做回收验证；若允许稀释提取，可先做小试比较回收率和背景。重点看批间差、阴性符合率和假阳性率，必要时用液相复核可疑样本，不要单靠胶体金结论。
