Trial Outcomes & Findings for Spartan FRX Project Reproducibility Study (NCT NCT01676298)

NCT ID: NCT01676298

Last Updated: 2013-01-07

Results Overview

Reproducibility was calculated as a percentage of the correct calls over the total calls made for each genotype group. All calls were made using the Spartan FRX CYP2C19 genotyping diagnostic system. All data analyses was qualitative, based on the genotype calls determined by the FRX system (using on-board automated data analysis). A printed result listing the genotype call for each SNP was generated by the FRX system at the end of each run. If the result of a test is "Inconclusive" for one or more SNPs, the test were immediately repeated for the corresponding SNP(s) only, per the instructions for use. Results are reported based on both first-pass and second-pass (i.e. repeated test). For both the first-pass and second-pass results, 1-sided 95% confidence lower limits were calculated using the score method for the % correct calls (i.e. % agreement).
