Tempus xT Solid Tumor + Normal Match DNA Sequencing

Tempus xR Whole Transcriptome RNA Sequencing

Our DNA and RNA sequencing services offer a comprehensive view of patients’ genomic profiles, equipping physicians to make informed treatment decisions.

xT Solid Tumor + Normal Match is a 648 gene DNA seq panel that reports clinically relevant alterations, immunotherapy biomarkers such as MSI and TMB, HLA Class I genotyping, as well as potential germline findings. Paired normal match sequencing utilizes a patient’s own genome as a comparator in comprehensive genomic panels, resulting in a more personalized sequencing analysis.

xR is a whole transcriptome RNA seq panel for solid tumors and hematologic malignancies that reports clinically relevant1 fusions for more than 100 targeted genes,2 as well as altered splicing events for MET exon 14 and EGFRvIII, in an unbiased and comprehensive manner.

POWER OF RNA

43.4% of patients matched to a targeted therapy when DNA sequencing was combined with RNA-seq and immunotherapy biomarker results.3

Among patients with identified fusions, 29% more patients were identified with a unique clinically actionable fusion that could be matched to a targeted therapy when RNA seq was incorporated, compared to DNA seq alone.4

SOLID TUMOR + NORMAL MATCH

Comparing tumor mutations to matched normal samples helps identify true somatic variants with improved accuracy.

28% reduction in somatic false-positive calls when using tumor-matched normal sequencing compared to tumor-only analysis.3

SMART REPORTS

Our reports include actionable information based on clinical and molecular findings, expanding clinical trial opportunities for patients.

Tempus incorporates information from the MSK OncoKB database and NCCN Guidelines®5 into clinical reports, providing therapeutic match options.

96% of patients matched to a clinical trial when clinical data was combined with Tempus NGS.3

OPTIONAL ADD-ON TESTS

Employing AI capabilities and leveraging our molecular and clinical database, CAP/CLIA lab, and clinician network, Tempus offers optional add-on testing to provide valuable insights for the treatment of patients with cancer.

IHC Options (available with any xT or xR test):

  • PD-L1 Clones: 22C3, 28-8, SP142, SP263
  • MMR: MLH1, MSH2, MSH6, PMS2

Algorithmic Tests (available add-on tests to xT Solid Tumor/Normal Match DNA seq + xR RNA seq without the need for additional tissue):

  • Homologous Recombination Deficiency (HRD)*
  • Tumor Origin (TO)†
  • DPYD**
  • UGT1A1**
  • PurISTSM†

* xT solid tumor + normal match DNA seq required for breast and ovarian cancer HRD testing. All other cancers require xR RNA seq.
⤈† xR RNA seq required
