Guidelines on Representative Drug Sampling
The Guidelines describe a number of sampling methods, from arbitrary methods to methods with a statistical background. Focus is on sampling in cases where large numbers of relatively homogeneous material are available.
The Guidelines aim to support drug analysis laboratories in the selection of their sampling strategy(ies) and best working practices.
As sampling is dependent on a number of parameters, including the original question, the final aims of the investigation, and the legal requirements, the sampling methods described in these Guidelines will have to be tailored to specific situations or cases and evaluated to be fit for the intended purpose.
