About the BreastSentry Test

BreastSentry measures the levels of two biomarkers, proneurotensin (pro-NT) and proenkephalin (pro-ENK), which are highly predictive of a woman’s risk for developing breast cancer. Elevated levels of pro-NT and decreased levels of pro-ENK are strong, independent risk factors for the development of breast cancer (1-5). BreastSentry provides women with additional information about breast health beyond mammography. Women with elevated BreastSentry scores may need to be referred for advanced imaging tests, such as breast MRI or Ultrasound in addition to a screening mammogram.

BreastSentry needs to be prescribed by a physician and is available through AVRT, StageZero’s comprehensive telehealth program that uses advanced diagnostics and physician supervision to help patients detect cancer in the earliest stages.  Whether you have a family history of cancer or are simply concerned about developing cancer, our physicians can work with you to develop a patient-centric, personalized care plan to help optimize your health.

BreastSentry is for any woman who needs further evaluation of breast cancer risk. 
The BreastSentry Test is intended for use in women without a personal history of breast cancer. Patients with a known history of impaired renal function are not candidates for the BreastSentry test.


AVRT is a New, Revolutionary Approach to Healthcare!

AVRT is a comprehensive, physician supervised telehealth program which uses advanced diagnostics to help detect cancer and chronic disease in the earliest stages when they are highly treatable, along with lifestyle and pharmaceutical management.

What Kinds of Testing Do You Offer?

AVRT works with StageZero Life Sciences, a CLIA Certified, CAP Accredited High Complexity Laboratory in Richmond, VA to provide the most advanced testing for early cancer detection. Tests available through Stage Zero include:

AVRT Panel

A comprehensive panel including inflammatory markers and metabolic function tests to help identify early warning signs of chronic disease and metabolic conditions.  ​

ARISTOTLE

Aristotle is a blood-based mRNA Multi-Cancer Panel for Identifying the molecular signatures of multiple cancers from a single blood draw(6)

ColonSentry

ColonSentry® is a blood test that uses advanced mRNA gene expression technology to help identify Colorectal Cancer (CRC) early when it’s most treatable (7).

BreastSentry

BreastSentry is a blood test that can help identify if a woman has an increased risk for developing breast cancer (3).

PHI

The Prostate Health Index is an FDA approved blood test that can help men with elevated PSA to differentiate benign prostate conditions from prostate cancer (8,9).
