2.1. Periodic or skip testing
Periodic or skip testing is the performance of specified tests at release on pre-selected batches and / or at predetermined intervals, rather than on a batch-to-batch basis with the understanding that those batches not being tested still must meet all acceptance criteria established for that product. This represents a less than full schedule of testing and should therefore be justified and presented to and approved by the regulatory authority prior to implementation. This concept may be applicable to, for example, residual solvents and microbiological testing, for solid oral dosage forms. It is recognized that only limited data may be available at the time of submission of an application (see section 2.5). This concept should therefore generally be implemented post-approval. When tested, any failure to meet acceptance criteria established for the periodic test should be handled by proper notification of the appropriate regulatory authority(ies). If these data demonstrate a need to restore routine testing, then batch by batch release testing should be reinstated.

按照这种说法,skip test应该是被允许的,但是一般是会是post-approval(即后期的变更中进行),并且应该为regulatory authority批准后实施的变更(原文举例了口服固体制剂的溶剂残留和微生物限度检测,那么这样说来,原料药也应该是可以实施的,不知道是否对于其他高风险的工作量应该是很大的),同时提及到如果后期出现skip test failure的话,应该通知相应的regulatory authority,并且会存在被要求进行 full test的可能。
