Reference test samples for forensic applications based on GTFCh ("Association of Toxicological and Forensic Chemistry") proficiency testingsMEDICHEM provides reference material for internal accuracy and precision testing. Precision testing focuses mainly on the longitudinal expansion of the single control test within the quality control batch, i.e. a specific concentration range next to legal or generally applicable boundary values. Materials for precision testing do not necessarily have to be part of proficiency tests but they must not be used for accuracy testing.
Accuracy testing materials are additionally used to review the compliance level of the individual measurement result with the real value of the indicator. The compliance level has to be evaluated trustworthy by a minimum of representative testings with validated, mostly internal standardised and evident methods, especially proficiency tests.
For internal accuracy testing MEDICHEM provides both accuracy test samples as well as selected proficiency test samples, taken from proficiency GTFCh tests. This happens after the evaluation of the respective proficiency test and the successive result approval of the proficiency test authority. Those proficiency tests can therefore be used as reference test samples. As scientific, non-profit, and non-commercial organisation the GTFCh is generally not to be held liable.
