Your Result
Low Likelihood
High Likelihood
High Likelihood

The EpiSwitch Prostate Screening (PSE) Test result indicates a high likelihood of prostate cancer. This result is consistent with cancer being confirmed in more than 9 out of 10 men.

Your healthcare provider will consider this result along with other clinical features and history to determine which additional diagnostic test(s), such as a biopsy, is appropriate to confirm.

Validated test with high accuracy, specificity and sensitivity

  • EpiSwitch PSE is administered alongside or following a standard PSA test
  • Blood test measures five (5) epigenetic biomarkers and combines these with the patient’s PSA score
  • EpiSwitch PSE was validated across a population of asymptomatic men randomly invited for cancer screening

Our comprehensive and validated approach delivers a report to the ordering physician via secure electronic communication or fax. Results will be available around 5 days after the lab receives the patient's blood sample.

genomic database

Built on Oxford BioDynamics' EpiSwitch technology platform, PSE is based on a comprehensive and validated approach

The EpiSwitch PSE blood signature was developed using Oxford BioDynamics' EpiSwitch 3D genomic immune health database—the world's largest genomic database—via several controlled studies.

PSE uses 3D genomic profiling to assess an individual's current likelihood of prostate cancer. This method uncovers vital drivers of systemic changes in their blood, including immune cells associated with prostate cancer.
