These properties are in contrast to the superior standardization and sensitivity achieved by state of the art nucleotide sequencing technologies.
Other investigators have indicated that results from such studies are difficult to interpret because of a lack of standardization and sensitivity of the tests.
It has emerged as a powerful alternative forward genetics strategy to dissect the genetic and biochemical basis of metabolism, providing a useful approach for functional gene identification with more precision, standardization, robustness and sensitivity (Adamski and Suhre, 2013).
By combining metabolomics as a phenotyping tool with GWAS, the studies gain more precision, standardization, robustness and sensitivity.
In the 2005 Diabetes Autoantibody Standardization Program, workshop sensitivity and specificity for the GAD antibody assay were scored as 86 and 99%, for the IA2 antibody assay 64 and 100%, and for the IAA antibody assay 22 and 99%, respectively.
Even though further studies are needed (for example, on definitions of pathologies, standardization of methods, sensitivity to change, and prognostic value), it seems evident that both US and MRI have major potential for improved examination of joints, tendons, and entheses in fingers and toes of patients with PsA.
We are exploring modifications of the assay format in order to produce a more linear dose-response curve with clinical sera samples, which if found, would facilitate assay standardization and might increase sensitivity (note that 1 2 of the colon cancer responses to one of the antigens tested, β-catenin-Δ1, are barely below the cut-off value used to judge statistical significance).
Under realistic conditions not all of those characteristics can be fulfilled and as a matter of fact labelling provides no ultimate solution to all sensitivity and standardization problems, but it can be considered as another powerful tool in the toolbox of quantitative analysis.
Some of these outcome measures have been carefully standardized, whereas others need similar standardization and modification to improve sensitivity and specificity for investigating the health effects of air pollution.
According to the 2005 Diabetes Autoantibody Standardization Program, the disease sensitivities of these assays were 44, 82, and 72% and specificities were 98, 97, and 100%, respectively.
