4.two Despite the fact that a collaborative study is an element of this guideline, this guidebook may very well be used by an individual laboratory for method validation when a formal collaboration review just isn't simple. This tutorial might also be utilized just before a complete collaboration study to forecast the reliability of your method.

Any oblique test method ought to are already proven to correlate Along with the issue on the equipment. During validation, the agency need to document that screening the uncleaned devices offers a not suitable final result for the oblique exam.
