What to Expect from Your Results
You Will Receive One of Three Possible Outcomes
No Cancer Signal Detected
A No Cancer Signal Detected result means Caris Detect did not identify cancer-associated molecular signals in the blood sample at the time of testing. This result does not rule out cancer or mean that you will not develop cancer in the future.
Caris Detect is intended to complement, not replace, routine cancer screening and medical care, so you should continue recommended cancer screenings and routine preventive healthcare based on guidance from your healthcare provider.
Atypical Signal Detected
An Atypical Signal Detected result means Caris Detect identified molecular patterns that do not fall within the expected range for a Cancer Signal Detected result. These findings may be associated with a variety of biological processes, including processes unrelated to cancer, and do not confirm the presence of cancer.
Caris provides complimentary repeat testing approximately 3 months after the initial result, with clinical support provided throughout the process to help you understand your result and navigate appropriate next steps. Additional clinical evaluation may be appropriate based on your medical history, risk factors, symptoms, and other diagnostic findings.
Cancer Signal Detected
A Cancer Signal Detected result means Caris Detect identified molecular patterns in the blood associated with a cancer signal. This result is not a cancer diagnosis and should be followed by appropriate diagnostic evaluation. When available, Suspected Tissue of Origin guidance and a Recommended Action are provided to help inform targeted follow-up evaluation.
Clinical support is provided throughout the process to help you understand your result and navigate next steps. Caris may offer reimbursement for eligible physician-ordered services related to the result throughout the diagnostic process ¹. You should review your results and recommended next steps with your healthcare provider.

Disclaimers
Your purchase may be HSA/FSA eligible. Check with your plan administrator. Everlywell is not responsible for contacting your plan administrator on your behalf.
Everlywell works with a network of licensed clinicians who review your request and order the test. Caris Detect™ Multi-Cancer Early Detection Test is performed by Caris Life Sciences' CLIA-certified, CAP-accredited laboratory. Results are provided to you and made available in your online portal.
Caris Detect does not detect a signal for all cancers and not all cancers can be detected in the blood. False positive and false negative results may occur. Caris Detect is intended to complement, not replace, recommended cancer screening tests and other medical evaluations, so it is important that you continue recommended cancer screenings and routine preventive healthcare based on your individual risk factors.
Results should be interpreted in conjunction with discussion with your healthcare provider and potential follow-up diagnostic testing. A positive result is not a diagnosis. A negative result does not rule out cancer or mean that an individual will not develop cancer in the future.
Footnotes / Legal Disclosures
For patients who receive a Cancer Signal Detected result, Caris offers patient reimbursement for eligible physician-ordered services related to this result throughout the diagnostic process. If insurance processes the imaging claim in any way — even if the patient has a remaining out-of-pocket balance, including copayments, coinsurance, and deductibles — those costs are not eligible for reimbursement.
A 99.2% specificity means that approximately 1 in 100 individuals without cancer may receive a false positive result (Cancer Signal Detected). 99.2% specificity was established in a case-control validation study comparing samples from patients with known cancer to non-cancer controls. No prospective randomized controlled trials have yet evaluated Caris Detect's specificity in a general screening population.
Caris Life Sciences' molecular profiling platform has processed over 1 million tumor cases and 50 billion molecular markers. The AI model used specifically for multi-cancer early detection (MCED) in Caris Detect was trained on 2243 patients and validated on an independent blinded test set of 776 patients.
A Cancer Signal Not Detected result does not rule out cancer entirely. Caris Detect is intended to supplement, not replace, standard cancer screenings. Individuals should continue to get regular mammograms, colonoscopies, and other routine screenings based on individual risk factors.

About Caris Detect
Caris Detect looks for signals across a range of cancer types. Detection performance varies by cancer type and stage and has not been established for every type listed.
This test was developed and its performance characteristics determined by Caris Life Sciences. It has not been cleared or approved by the U.S. Food and Drug Administration. The FDA has determined that such clearance or approval is not necessary for laboratory developed tests (LDT). This laboratory is certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA) as qualified to perform high-complexity clinical laboratory testing.
Intended use
Caris Detect is a multi-cancer early detection laboratory-developed test performed in a CLIA-certified, CAP-accredited laboratory utilizing whole genome sequencing, whole transcriptome sequencing and advanced artificial intelligence. It is designed to detect early-stage cancer signals from cell-free DNA and cell-free RNA in the blood. Whole exome sequencing and whole transcriptome sequencing (Caris Assure®) are utilized for patients that receive a “Cancer Signal Detected” in order to provide the Suspected Tissue of Origin.
Caris Detect is intended for use as a screening aid in asymptomatic adults at increased risk for cancer (due to age, cancer predisposition, exposure history, etc.) with no prior history of cancer within the last 3-years, to identify individuals who may warrant additional clinical evaluation.
Caris Detect is not intended to diagnose cancer. A positive result should be followed by confirmatory diagnostic evaluation (e.g., imaging and tissue-based diagnosis) consistent with standard clinical practice. A negative result does not rule out cancer. The test does not detect all cancers, and false positives and false negative results may occur.
Caris Detect should not replace guideline-recommended cancer screening tests and is intended to be used in addition to standard screening recommendations.
Limitations of use
Caris Detect is intended for use in adults 21 years of age and older who meet the clinical criteria.
The test is not intended for use in individuals who:
Are under 21 years of age
Are currently pregnant or within 1 month postpartum, including following miscarriage
Have a current or prior cancer diagnosis within the last 3 years
Are undergoing active cancer treatment
Have received an allogeneic (donor) bone marrow or stem cell transplant. If autologous (self), it must be 6 months post-transplant to qualify.
Have received an organ transplant at any time
Caris Detect results should be interpreted by a qualified healthcare provider in the context of the patient's clinical history and other diagnostic findings.
Regulatory statement
This test was developed and its performance characteristics determined by Caris Life Sciences. It has not been cleared or approved by the U.S. Food and Drug Administration.
