Clinical utility

The OncoExTra® test can help you expose the many variants of advanced-stage cancer by providing thorough insights.

Panel-based and hotspot testing may miss genomic variants—some of which may be actionable1,2

DNA RNA Paired Tumor-Normal Match
Hotspot DNA
Hotspot RNA
Comprehensive genomic profiling
(Fixed panel DNA sequencing)
(whole-exome DNA sequencing + whole-transcriptome* RNA sequencing)
Allows for comprehensive analysis of all protein-coding genes in a sample


Allows the identification of transcript variants and fusions that may be undetectable through conventional CGP tests, which only employ DNA analysis3


*Whole-transcriptome with select variants reported in New York State

Understand the impact the test has on patients

Analytic validation and clinical utilization of the comprehensive genomic profiling test, GEM ExTra®.

Thoroughly interrogates
~20,000 genes through WES3



Sequences all transcripts
present through WTS

High accuracy with 98.8% sensitivity and >99.9% specificity3

Utilize patient-matched tumor-normal sequencing to further refine therapy selection

  • Limit false positives by identifying and ruling out benign variants in a patient’s tumor sample vs normal blood sample3
  • Reduce the overestimation of tumor mutational burden (TMB) calculations by excluding mutations also found in the normal sample3,4

Clinical Utility Bar graph

*Retrospective analysis of 1509 clinical reports, of which 1261 included both DNA and RNA profiling. Among the 75 reports with clinically actionable fusions detected in the RNA, 31 had RNA findings only.3
†Clinically actionable variants are defined as variants that are associated with available therapies or clinical trial enrollment for a specific somatic variant identified in a patient’s tumor.3
