多重耐药检测确实会提高污染和质控要求，但不一定需要大规模改线。可先评估现有分区、提取兼容性和扩增平台，建议采用带防污染措施的试剂，使用滤芯吸头、独立试剂准备区、阴性对照、弱阳性对照和内标，并定期核查移液器校准和一次性耗材。预算有限时可先小批量试用一个已验证的耐药多重方案，重点确认检出限、混合感染和型别稳定性。货期紧张时还要同时锁定质控品、耗材和培训支持。

普通肺炎支原体核酸试剂盒多数只确认靶标存在或定量，不一定覆盖耐药基因。若要筛查大环内酯耐药，需要明确说明书或验证报告是否包含23S rRNA常见突变及型别，不能把检出支原体等同于耐药检测。厂家称只能检测存在时，通常意味着没有突变位点探针或分型能力。建议按临床需求选专门耐药检测或测序，而不是在原试剂盒里自行加反应管或探针，这会带来性能确认和合规风险。
