GIST Profile

GTR Test IDHelpEach Test is a specific, orderable test from a particular laboratory, and is assigned a unique GTR accession number. The format is GTR00000001.1, with a leading prefix 'GTR' followed by 8 digits, a period, then 1 or more digits representing the version. When a laboratory updates a registered test, a new version number is assigned.: GTR000591198.1

Clinical testHelpIn the U.S., clinical tests must be performed under CLIA certification. When a lab uses the same methods for a test in both clinical and research settings, the test appears as two separate GTR records. for Gastrointestinal stroma tumor

KIT: The assay identified 1 mutation from the FFPE specimens and give 100% sensitivity and 100% specificity of the assay. Sensitivity=TP/(TP+FN)x100=1/(1+0)x100=100% Specificity=TN/(TN+FP)x100=1/(1+0)x100=100% BRAF: The assay identified 1 mutation from the FFPE specimens and give 100% sensitivity and 100% specificity of the assay. Sensitivity=TP/(TP+FN)x100=1/(1+0)x100=100% Specificity=TN/(TN+FP)x100=1/(1+0)x100=100% PDGFR: The assay identified 1mutations from all 2 DNA specimens and give 100% sensitivity and 100% specificity of the assay. Sensitivity=TP/(TP+FN)x100=1/(1+0)x100=100% Specificity=TN/(TN+FP)x100=1/(1+0)x100=100%
