When it is necessary to establish a threshold, that is, the clinical decision point, for a quantitative continuous biomarker, obtaining appropriate validation samples is frequently the rate limiting step in assay validation, so it is wise for the team to establish the strategy (purchase commercially or collaborate, e.g).
Indeed, as the originally postulated construct of the IADCQ did not obtain appropriate fit, further validation of the unidimensional model is important.
These sample types must be validated by the laboratory prior to being tested but often the validation may not occur or not done comprehensively due to the difficulties obtaining appropriate samples in sufficient quantity.
To date, the development and validation of radiation biomarkers in vivo has relied heavily on mouse models and more recently non-human primate (NHP) models due to the limitation in obtaining appropriate human samples8,9.
You are responsible for obtaining appropriate visas on time.
Students should take the CASE† to obtain appropriate placement.
The carcinoembryonic antigen (CEA) experience [21], [22] from 40 years ago, where non-reproducible results were obtained largely due to the variation among the test sets in terms of the 'spectrum' of disease, initially implied the vital importance of selecting appropriate validation samples in order to reliably assess the reproducibility of statistical modeling results.
Another precondition, equivalently important, is to define an appropriate validation methodology.
Based on the appropriate validation results, computer simulations were performed to build 3D color surfaces.
For the Armenian community, and without the appropriate validation, the genocide has simply never ended.
Appropriate cohorts of patients and appropriate validation procedures will be needed to this end.
