Quantitative bioanalytics in the 1970s and 1980s was often accompanied by peak height determination by ruler, integration with paper and scissors, packed GC columns, and less resolving LC columns. Science and research was based on quantitative data, which was widely accepted as correct, although quality control testing was not generally implemented in university, clinical, or industry laboratories. During those years, doubts arose in particular regarding the correctness of ecological data of plant protection agents, insecticides, and highly chlorinated hydrocarbons, which led to the development of the stringent rules of Good Laboratory Practice (GLP). These rules were incorporated into federal law in many countries and still represent one main cornerstone in supervision for the registration of new chemical entities and in the pre-clinical stage of pharmaceutical drug development.

Aside from these developments, first discussions on how to prove analytical correctness within bioanalytical quantification resulted in famous conference reports [1,2]. During the 1990s, striking analytical developments in chromatography (e.g. 3 μm size particles, varying chemistry in stationary phases) and mass spectrometry (e.g. electrospray ionization, ion trap and tandem mass spectrometry) were achieved, and LC/MS/MS techniques began to enter university and clinical laboratories. The quantification of drugs and metabolites in all kinds of biological matrices gained more and more scientific value, driven by the possibility to answer further pharmacological questions using new LC/MS/MS techniques. To follow the progress in bioanalytical methodologies, an update of the validation procedures was necessary, resulting in another conference report [3] in 2000 and in the FDA Guidance for Industry: Bioanalytical Method Validation [4] in 2001. In recent years, further advances in analytical techniques (e.g. sub 2 μm particles (UHPLC), high-resolution tandem mass spectrometry (QTOF)) have been made, selectivity and sensitivity were significantly improved, and the FDA Guidance became established in the worldwide bioanalytical community. This year, the European Medicines Agency (EMA) put its own guideline on bioanalytical method validation [5] into force, which implemented some new aspects, but remained largely based on the established fundamentals of the FDA Guidance.

The development of bioanalytical method validation principles over the last two decades is an example of a well-accepted regulation within an area of science and scientific research. These validation procedures, defined as guidance, are not written into general law, but nevertheless describe the view of the registration authorities. Therefore, scientific journals publishing new bioanalytical methods should also put a main focus on the quality of applied method validation, and the reviewers should check manuscripts particularly for sufficient and appropriate validation procedures.
