Frequently Asked Questions
WHAT IS EPISEEK™?
The Precision Epigenomics liquid biopsy test, EPISEEK™, is a blood-based multi-cancer detection test designed to accurately assess DNA shed by tumors called circulating tumor DNA (ctDNA) to detect cancer from a simple draw. We analyze epigenomic modifications present in the ctDNA. Proprietary software is used to analyze the data to generate a report that specifies if an abnormal methylation signal is present or if no cancer signal is detected.
WHICH CANCERS SHOULD EPISEEK™ DETECT?
EPISEEK™ was designed to detect the presence of abnormal DNA changes shared by more than 60 cancer types, including the most deadly tumors—e.g., lung cancer, breast cancer, prostate cancer, colorectal cancer, pancreatic cancer, head and neck squamous cell carcinoma, bladder cancer, and esophageal cancer—ALL of which have been detected by the assay. EPISEEK™ also detected cervical squamous cell carcinoma, endocervical adenocarcinoma, ovarian carcinoma, bile duct carcinoma (cholangiocarcinoma), DLBC lymphoma, liver hepatocellular carcinoma, thyroid cancer, gastric adenocarcinoma, uterine endometrial carcinoma, brain glioma, cutaneous melanoma, cutaneous squamous cell carcinoma, testicular germ cell tumor, and plasma cell myeloma, among others. It’s important to note that the test has lower sensitivity in early-stage cancers and should not be considered a replacement for recommended cancer screening such as colonoscopy, mammogram, cervical cancer, and lung CT screening.
WHAT ABOUT FALSE POSITIVES?
EPISEEK™ is a screening test designed to identify asymptomatic patients. Screening tests are designed to rule in a disease state and to minimize false positive results in healthy individuals. This test may not perform as well in patients with a personal history of cancer or with symptoms or clinical findings that make cancer more likely.
DOES EPISEEK™ PREDICT MY RISK OF DEVELOPING CANCER?
No. The Precision Epigenomics liquid biopsy test does not screen for hereditary risk of developing malignancy. It is designed to detect the presence of malignancy.
WHICH PATIENTS CAN TAKE EPISEEK™?
As with many cancer screening guidelines, our liquid biopsy test is recommended for use in adults aged 45 or older. Patients younger than 45 but with elevated risk factors might also benefit from testing. EPISEEK™ testing is not recommended for patients younger than 21, those who are pregnant, those who have an active known malignancy, or those who are currently being treated for cancer.
WHY ARE CONVENTIONAL RECOMMENDATIONS FOR CANCER SCREENING STILL APPROPRIATE IF A PATIENT TAKES EPISEEK™?
The test should not be considered a replacement for routine cancer screenings, such as colonoscopy, mammogram, and cervical cancer screening. Healthcare providers should continue to follow guideline recommendations for cancer screening in their patients.
WHO CAN ORDER EPISEEK™?
An appropriately licensed medical provider who cares for the patient and is permitted to order laboratory testing in their jurisdiction, including MD, DO, ND, DDS, DPM, OD, NP, DC, and PA.
IS EPISEEK™ RECOMMENDED IN CANCER-SCREENING GUIDELINES?
Liquid biopsy for multicancer detection is not yet recommended by major cancer-screening guidelines or by the US Preventive Services Task Force (USPSTF).
WHAT IS THE RECOMMENDED SCREENING INTERVAL FOR EPISEEK™?
Annual health exams may be an appropriate time for a multi-cancer detection test such as our liquid biopsy test, but patients are encouraged to discuss screening with their healthcare provider to determine an appropriate interval given their unique healthcare considerations. There are no specific guidelines on liquid biopsy multi-cancer detection liquid biopsy tests.
WHERE IS THE TEST CURRENTLY AVAILABLE?
The test is currently available to most patients in the United States and abroad. We cannot currently accept samples that were collected in New York State.
Cost and Coverage
HOW MUCH DOES EPISEEK™ TESTING COST?
For domestic patients, the fee of $699 covers the test-collection kit, the transportation materials, the delivery of the kit to the provider’s office, the return overnight shipping to our clinical laboratory, the analysis, and the interpretation with a final report. For international testing, the kit shipping fees to and from the lab in Tucson are an additional cost.
IS THE TEST COVERED BY INSURANCE?
Currently, EPISEEK™ is not covered by major insurance carriers, including Medicare.
CAN MY PATIENTS USE THEIR HSA OR FSA TO PAY FOR THE TEST?
Because policies vary among HSA and FSA administrators, patients should contact their insurance companies or plan administrators for details on using their accounts for Precision Epigenomics’ liquid biopsy test. In general, patients have been able to use their HSA/FSA for EPISEEK™.
Test Ordering and Logistics
HOW CAN A LICENSED HEALTHCARE PROVIDER ORDER EPISEEK™ FOR THEIR PATIENT?
Test kits can be ordered through support@precision-epigenomics.com. The test requisition must be completely filled out and returned to the laboratory with the specimen in order for the specimen to be processed.
WHAT ARE THE SPECIMEN REQUIREMENTS FOR EPISEEK™?
A peripheral whole-blood specimen, submitted in the two Streck Cell-Free DNA tubes (10 mL each) that are provided in the collection kit, is needed for analysis. The patient need not fast or skip medications. Because the laboratory intends to process the specimen the day after collection, specimens should be collected and submitted only on days that precede workdays (typically Monday through Thursday morning, excluding holiday weekends). Specimens must not freeze, and they should be stored and transported at 37–87°F. A specimen will be rejected if it is submitted in blood collection tubes other than the provided Streck Cell-Free DNA tubes, submitted in expired collection tubes, less than 10 mL total, illegible or not properly labeled with two unique identifiers, hemolyzed or clotted, not received within 48 hours of collection, or not accompanied by a complete order.
DO PATIENTS NEED TO FAST OR OTHERWISE PREPARE FOR THIS TEST?
No special preparation, pausing of medication, or fasting is required. Other blood collection tubes for other tests collected at the same time will not interfere with EPISEEK™. High-intensity exercise within six hours prior to specimen collection may impact test results, so this should be avoided.
WHEN WILL MY PATIENT’S TEST RESULTS BE READY?
In most cases, the test results are available in about one week from arrival in our laboratory.
HOW WILL I RECEIVE THE TEST RESULTS?
Currently, Precision Epigenomics receives orders from the clinician and issues reports by fax. Patients should be in touch with the ordering clinician if they have not received results within two weeks from their blood collection date.
Results Interpretation
WHAT DOES “CANCER SIGNAL NOT DETECTED” MEAN?
We designed EPISEEK™ to detect abnormal methylation patterns that may be present as circulating tumor DNA in the blood of patients with cancer but not present in normal blood or other tissues. In this case, the test did not detect these characteristic DNA methylation abnormalities. EPISEEK™ was not designed to detect all malignancies.
Not all cancers have enough abnormal DNA circulating in the blood to be detected. While EPISEEK™ was designed to be sensitive, a “Cancer Signal Not Detected” result does not completely rule out the presence of cancer. Patients who receive a “Cancer Signal Not Detected” result should continue with all standard-of-care screening options at intervals appropriate for that individual.
WHAT DOES “ABNORMAL METHYLATION SIGNAL DETECTED” MEAN, AND WHY DOES IT NEED TO BE CONFIRMED WITH DIAGNOSTIC TESTING?
Screening tests usually do not diagnose cancer. They are designed to detect possible cancer in an otherwise healthy population. For example, a screening mammogram may find a density in the breast. That lump may be cancer or something else. An elevated prostate-specific antigen (PSA) level might be found as part of a man’s wellness check. It might be due to cancer or inflammation. Similarly, if a screening test such as Precision Epigenomics’ liquid biopsy test is abnormal, more tests may be done to determine if cancer is present. We designed EPISEEK™ to be a screening test, not a diagnostic test.
WHAT DIAGNOSTIC TESTS SHOULD BE ORDERED TO CONFIRM A DIAGNOSIS FOR AN “ABNORMAL SIGNAL DETECTED” RESULT?
The evaluation of a patient with an abnormal screening test result, such as “Abnormal Methylation Signal Detected” by EPISEEK™, must be managed by the patient’s qualified healthcare provider. This may include detailed history and physical examination with special attention to known risk factors, additional laboratory studies, studies such as PET/CT imaging, and even tissue biopsy, among other diagnostic maneuvers. “Abnormal Methylation Signal Detected” by EPISEEK™ does not equate to a diagnosis of cancer.
WHAT IF THE DIAGNOSTIC WORKUP SHOWS NO SIGN OF CANCER FOR A PATIENT WITH AN “ABNORMAL SIGNAL DETECTED” RESULT?
The evaluation of a patient with an abnormal screening test result, such as “Abnormal Signal Detected” by EPISEEK™ must be managed by the patient’s qualified healthcare provider. This may include a detailed history and physical examination with special attention to known risk factors, additional laboratory studies, and studies such as PET/CT imaging or full-body MRI, among other diagnostic maneuvers.
For patients with no visible signs, symptoms, or previous diagnosis of cancer, a positive (Abnormal Methylation Signal Detected) result from EPISEEK™ signals the need for further evaluation. In such cases, a Precision Epigenomics pathologist will collaborate with the ordering provider to determine the most appropriate next steps, typically a PET/CT scan or full-body MRI for comprehensive imaging.
Recognizing that insurance may not always cover these advanced imaging procedures, Precision Epigenomics is committed to supporting patients and their healthcare providers by covering up to $2,000 of the scan’s cost if financial barriers exist.
WHAT DO I DO IF I RECEIVE A “CANCELED” TEST RESULT?
For a variety of reasons—such as a hemolyzed specimen, unlabeled specimen, insufficient specimen quantity, delayed transportation, or technical difficulties in the laboratory—the specimen may be reported as canceled. Please contact our laboratory at (520) 372-7522 or support@precision-epigenomics.com to coordinate the submission of an additional specimen to be tested at no further cost to the patient.
WHERE CAN I FIND MORE INFORMATION ON THE TEST AND PATIENT-INFORMED CONSENT?
We understand the importance of providing comprehensive information to patients regarding the testing procedures and results.
For individuals seeking comprehensive information about the test and the associated informed consent, both patients and clinicians can turn to our Terms of Service. There, you can access easy-to-understand resources explaining the nature of the test, its benefits, and any potential risks involved. Additionally, the Terms of Service and Precision Epigenomics’ website provide comprehensive details on the informed consent process and the EPISEEK™ test, empowering individuals to make well-informed decisions about their healthcare.
We encourage both patients and clinicians to review in depth our Terms of Service and informed consent available at precision-epigenomics.com.
WHAT DOES THE NATIONAL CANCER INSTITUTE (NCI) SAY ABOUT MULTI-CANCER DETECTION (MCD) TESTING?
We believe that clinicians and their patients should read and understand the position of independent groups on what is known and not yet known about MCD testing, such as EPISEEK™. This can help with supported (shared) decision-making on whether MCD testing is right for them.
