The phrase "assay the validity" is correct and usable in written English.
It can be used when discussing the process of evaluating or testing the truth or accuracy of something, often in a scientific or analytical context.
Example: "Before proceeding with the experiment, we must assay the validity of our initial hypothesis to ensure its reliability."
Alternatives: "evaluate the validity" or "test the validity".
While more complex assays improve the validity of Drosophila as a model system to study drug addiction, these assays are necessarily more cumbersome and time-consuming, thus making large-scale genetic screening difficult.
The values of the interassay and intraclass correlation coefficients were high with rivaroxaban for the three chromogenic assays support the validity of this determination from serum samples despite minor systematic differences between the three tests.
Reference standards were run as an integral part of each assay to ensure the validity of the results obtained.
Both of these findings support the idea that discrepancies between the datasets are related to differences in assay sensitivity, not the validity of targets.
Three major issues should be considered when designing biomarker studies: selection of appropriate biomarkers, the assay (laboratory validity), and the population validity of the selected biomarkers.
Deutschbauer et al. (2005) tested 30 HI genes in individual growth assays to prove the validity of the molecular bar-coding to reproducibly score quantitative fitness differences as small as 2%.
The hierarchy of outcomes that results from prioritising objective outcomes over subjective ones, a hierarchy that is being promoted by the use of new scientific technologies such as MRI scans and biochemical assays, severely compromises the validity of outcome measurement for complex interventions.
The other three problems described here relate to the quality of the assays performed rather than the validity of the assays themselves.
For the Triad Multi-Marker test [15] (TRIMM; see below), deviation from HWE (p<0.05) was used to search for assay problems directly, since the validity of TRIMM does not require SNPs to be in HWE.
Whereas analytical validity refers to the quality of the laboratory assay, clinical validity is a criterion of the interpretation of assay results, a criterion of the test [ 30].
