Only one approach can guarantee quality generics: rigorous oversight, including unannounced inspections and systematic testing of drugs.

只有一种方法可以保证仿制药的质量：严格的监督，包括飞行检查和系统的药物测试。

For example, it has taken so far the OECD 10 years to devise a battery of tests that they could recommend for systematic testing of chemicals for developmental neurotoxicity.

例如，到目前为止，OECD 花了 10 年的时间才设计出一系列测试， 他们可以推荐这些测试用于对化学品的发育神经毒性进行系统测试。
