Focused on molecular liquid biopsy cancer diagnostics since 2014
Wren Laboratories is a CAP and CLIA-certified clinical testing and R&D laboratory established in 2014. The laboratory was founded as a commercial extension of their decades of academic and medical research into non-invasive liquid biopsy tests for a wide variety of cancers and other diseases that can be detected and better understood via molecular biomarkers such as mRNA.
Our Mission
When it comes to managing cancer, knowledge is power.
At Wren Laboratories, our liquid biopsy-based diagnostics use molecular science to uncover precise information about cancer in real time, enhancing pathology and imaging. We help oncologists clarify cancer diagnoses so they can recommend, manage, and monitor treatment better.

Creators of The NETest
The first commercial offering from Wren Laboratories was the NETest, an in vitro blood-based liquid biopsy that assesses the targeted gene expression profile of mRNA isolated from peripheral blood to diagnose neuroendocrine tumors. Since its availability in October 2014, oncologists have utilized our test over 10,000 times to assist in characterizing neuroendocrine tumors, recommending treatment, and monitoring tumor behavior during recovery.

About the Wren Brand
Brand Origins Reflect the History of and Our Enthusiasm for Our Science


Sir Christopher Wren
Most famous as an architect, Wren was also among the first to draw blood from human veins and helped develop mathematics into a fine art that could be applied to gaining scientific insights.


Our Way is mRNA
While most molecular diagnostics utilize DNA or protein, we’ve always focused on mRNA. It offers a high-resolution view of tumor activity. It’s a proven biomarker, having been used successfully since the late ‘90s. And, when preserved in our proprietary buffer solution, it’s stable.


What Wren Means to Us
Wren embodies the imagination and ingenuity necessary to harness the power of molecular genomics to better understand cancer. We are passionate about how our diagnostics help oncologists know more about and better manage cancer.
