Every patient is unique. Your treatment should be, too.

Genomic testing identifies alterations in your genes that can help guide potential treatment options based on your unique diagnosis and test results. The information from your genomic test can support you and your doctor in making informed decisions on the best care along your journey. Your doctor will order the appropriate Tempus test.

Disease Monitoring

Circulating tumor DNA (ctDNA) refers to cancer DNA that is present in the bloodstream. Minimal residual disease (MRD) testing can detect ctDNA that may be present after treatment, such as surgery or chemotherapy. This can help your doctor understand if there is any remaining disease following your treatment and help decide the best next steps.

Your doctor may also use this type of test to monitor your response to treatment, and guide potential adjustments to your care plan.

Your doctor may choose to order multiple disease monitoring tests to track your condition over time. Your doctor will select the MRD test that is right for you.

  • xM: Test using your blood sample

  • xM (NeXT Personal® Dx) test by Personalis: Test using your tumor tissue and blood sample

Biomarker Testing

Many cancers are caused by changes, or alterations, in our genes that may happen by chance or due to environmental factors. Biomarker testing, or molecular testing, looks for these specific alterations in our genes, which can help your doctors understand your unique cancer. Identifying alterations in your cancer may help your doctor choose therapies and personalize your treatment plan.

Your doctor will select the biomarker test that is best for you.

  • xT or xR: Test using your tumor tissue

  • xF or xF+: Test using your blood sample

Hereditary Risk

Hereditary cancers are caused by changes, or alterations, in our genes that may be inherited from a parent and passed on to one’s children. Genetic alterations that a person has had since birth can increase one’s risk for developing cancer.

Hereditary testing, also called germline testing, is used to look for these changes in our genes to detect alterations that may increase you or your family’s risk for cancer.  The most common hereditary cancers are breast, ovarian, colorectal, endometrial, prostate, and pancreatic cancer.

Your doctor will choose the hereditary test that is right for you.

  • xG (CancerNext®) or xG+ (CancerNext-Expanded®): Test using your blood or saliva

How is my information used?

Please see our Privacy Policy and our HIPAA Notice of Privacy Practices for more information.

I received one or more Explanation of Benefits (EOB) from insurance, what should I do next?

Nothing. An Explanation of Benefits (EOB) is not a bill; it is a communication from your insurance company regarding the Tempus services you received. It shows services that were billed to insurance and what insurance covered. An EOB may not require payment even if there is an amount due for patient responsibility. Patients may receive multiple EOBs if bundled testing options are selected by your provider.

What happens if insurance denies coverage?

If coverage is denied, Tempus will file an appeal(s) with your insurance company to pursue coverage on your behalf. We may contact you or your physician for assistance during the appeal process, as needed. Tempus will not bill you for services not allowed by your insurance company.

What happens if my insurance company sends a check to me for my Tempus test?

Tempus will send a bill to you for the amount owed once we are notified by your insurance company. You may pay the bill to Tempus, or endorse the check from your insurance company to Tempus by signing the back of the check on the top line of the endorsement area and writing “pay to the order of Tempus Labs” on the second line.
