From the BEST document, validation, for biomarkers and clinical outcome assessments, is a process to establish that the performance of a test, tool, or instrument is acceptable for its intended purpose.

In this Review, we describe proteomics and chemoproteomics approaches for target identification and validation, as well as for identification of safety hazards. Am. It should be noted that for the notoriously challenging task of efficacy target identification in phenotypic drug discovery, chemoproteomics is often and most successfully used as part of a multipronged strategy that also includes functional genetic, cellular profiling and computational approaches to generate as much complementary information as possible to hone in on the efficacy target amongst the hit lists of physical and functional interactors [Citation7274]. Nat. Reinhard, F. B. M. et al. These multi-omics datasets not only can provide insights into differential protein or metabolite expression associated with disease phenotypes and lab measures, but they can also be used to look for protein quantitative trait loci (pQTLs) which help interpret genetic associations. Techniques such as BioID [Citation189], APEX [Citation190] and FLARE [Citation191] have emerged as extremely useful tools to study more transient intracellular interactions, however, there are limitations to their utility on occasion as they require protein tagging, hence potentially changing native biological properties of the target protein. Wright, M. H. & Sieber, S. A. Cell 36, 326339 (2009). Boike, L. et al. Nature 575, 217223 (2019). This includes more sensitive sample preparation on more diverse cellular types and biological fluids, data collection, and analysis.
