We first investigated a number of variables that could conceivably affect CTC recovery and enumeration using the CellSearch® platform, including EpCAM expression, CTC number, time to analysis, and variations when samples are analyzed in different reference labs using the same platform.
Of these covariates, day of week, trip, collection device, vitamin use, pollen, mold, apparent temperature during the current hour, time to analysis, and nitric oxide concentrations in the testing room were selected for inclusion in our models.
The KRAS analysis process was also evaluated in terms of time to analysis result, analysis procedure and reporting, and investigators' subjective satisfaction with the process of molecular pathological analysis and its logistics.
Technical variation can be caused by the different steps of the experiment such as sample preparation, isolation of cellular components, labelling, hybridisation and time to analysis [ 6, 7, 9].
Samples of FENO collected before and after the trips were regressed against microenvironmental and ambient particle concentrations using mixed models controlling for subject, day, trip, vitamins, collection device, mold, pollen, room air nitric oxide, apparent temperature, and time to analysis.
Usability issues related to EDC for clinical trials have been discussed by Schmier, et. al., where it has been reported to contribute to decreased costs, enhanced quality of the data, and minimized time to analysis.[ 12] Finally, a real time quality control mechanism needs to be in place for assessing and correcting data entry errors.
