Did You Know That An Estimated 20% of Breast Cancers are Missed at Least Once by Mammography?1

BreastSentry is blood test that can help identify women at greater risk for breast cancer.

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 (2-5). 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 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. BreastSentry needs to be prescribed by a physician and is available through the AVRT telehealth program.

How it Works

Complete your online intake form to determine your eligibility for testing.

After you make your secure online payment for your test, we’ll schedule testing at a lab near your or arrange for a mobile phlebotomist to come to your home.

When we receive your test results, we’ll reach out to schedule a time to review them with a telehealth physician.

Additional Testing for Early Cancer Detection

In addition to the AVRT panel, we offer advanced blood tests for early cancer detection*. These tests are offered by StageZero Life Sciences, a CLIA Certified, CAP Accredited High Complexity Laboratory in Richmond, VA.  Be sure to ask your case manager about any of the tests below. Pricing and availability vary.
