Tempus xE Whole Exome

xE is a whole exome 19,000+ gene panel by DNA seq that provides potentially actionable and biologically relevant alterations, TMB, as well as potential germline findings.

Ordering Flexibility

Tempus offers a variety of options to customize molecular profiling for patients.

  • xE and xR may be ordered as a standalone test or in combination
  • Streamlined ordering process through Tempus Hub, paper requisition, or directly from your EHR

The analysis of xE paired normal match includes potential germline findings that may be reported in a limited set of 110 genes (including both hereditary cancer and non-cancer related genes) and may or may not be related to the patient’s current cancer diagnosis.* Potential germline gene selection for reporting was based on ACMG recommendations 1 , NCCN Guidelines Ⓡ2 , and other published literature.

* Normal match sequencing is utilized to ensure fidelity of somatic variant calling. Tempus xE is not a validated germline panel, and potential germline findings should not be used as a diagnostic determination for hereditary cancer risk.
