Recommendations from the European Bioanalysis Forum on method establishment for tissue homogenates.

Tissue analysis has always been a difficult discipline of bioanalysis. Differences in scientific approaches or level of adherence to regulated guidelines have led to a growing ambiguity on how to perform tissue analysis, an ambiguity that starts with the question of if we analyze tissue or tissue homogenates. The European Bioanalysis Forum (EBF) is proposing a recommendation on how to perform method establishment and analysis of tissue homogenates.

Feedback from a European Bioanalysis Forum survey on bioanalysis of drugs in tissues.

Tissue analysis has always been a difficult discipline of bioanalysis. Laboratories that perform bioanalysis in tissue are facing a lot of challenges and questions before starting experiments, from a scientific/technical point of view regarding more regulated aspects. Actually, literature is poor regarding the more technical and scientific aspects but also beyond that no clear guidance is available on this topic and laboratories performing tissue analysis face real ambiguity regarding regulatory requirements, always with the risk of under- or over-validation of the assay.
