TESTING WORKFLOW
How MI Cancer Seek Works
MI Cancer Seek is authorized as a companion diagnostic to identify patients who may benefit from treatment with the targeted therapies listed below.

Tumor Tissue Collected
A tissue sample is collected during a biopsy or surgical removal of your tumor.

DNA and RNA Sequencing Performed
Simultaneous WES/WTS delivers a more complete picture of the biomarkers driving your cancer.

Genomic Alterations Identified
Advanced bioinformatics identify clinically relevant genomic alterations and molecular signatures from DNA and RNA sequencing data.

Clinical Report Delivered
Results are delivered to the ordering physician within 6-9 days of specimen receipt, providing molecular insights to help personalize treatment based on the patient’s distinct cancer.

AFFORDABILITY
Financial Flexibility for Patients
At Caris, we believe cancer testing should be accessible to everyone. Our team is ready to support you with any insurance or billing questions.
Many patients don’t realize
- If you are uninsured or worried about cost, we offer financial assistance programs to help eligible patients get the testing they need without added stress.
- Caris maintains in-network coverage with most major commercial payers nationwide, including national coverage through Medicare and Medicare Advantage. Qualifying Medicare/Medicaid patients have no out-of-pocket responsibility.
- Most patients will be responsible for less than $100 USD out-of-pocket, including co-pays, co-insurance and deductibles. If your invoice is $100 USD or more, Caris will call you to discuss financial assistance options.
