Table 1 Inter-assay summary data for replicates 1 and 2 vs 3 and 4 were used for the evaluation of Class call concordance. 30 FFPE available samples were run in duplicate, for a total of 4 replicates, over 2 days by two different technologists and using two different machines. The individual sample class call averages of the replicates are shown

From: Analytical validity of DecisionDx-SCC, a gene expression profile test to identify risk of metastasis in cutaneous squamous cell carcinoma (SCC) patients
