About Danner Laboratory

In 1991, Danner Laboratory was founded in San Diego, California and has evolved
into a leading provider of clinical cytopathology testing services that
specializes in precision healthcare.

With a mission on emphasizing liquid biopsy and preventive oncology, our CTCReveal™
testing service is the future of non-invasive Circulating Tumor Cell (CTC) screening at early
metastatic stage of cancers. This new service aims to reduce the high mortality
rate and help in managing cancer treatment.


CTCReveal utilizes CellBio™ technology, developed by GBC, Taiwan (parent company).
This new technology has been recognized for its excellence by Edison Awards, 2025
in the “Cancer Diagnostics and Treatment Technologies” category.

Recently, we have integrated our lab with an AI-assisted digital imaging platform
CellSPOT-300™ to enhance detection accuracy and consistency of cytopathology
slides, as well as CTCReveal testing.

Why it Matters

Liquid biopsy is the future of cytopathology and cancer detection. Modern day methods for discovering and diagnosing cancer are too expensive and invasive. At Danner Laboratory, we are pioneering the future of preventive oncology. This allows people to recognize their own biological risks, before the disease has an opportunity to spread and become fatal. This feat is accomplished in a manner that is timely, cost-effective, and incredibly efficient.

CTCReveal™ allows for early detection before tumors become visible. Since this service is noninvasive, it is not only safe, but repeatable to proactively monitor the status of cancer in an individual. This allows people to gain an understanding of the early warning signals and take steps to prevent further development. Not only does this pave the way in the future of cancer research, it increases accessibility to cancer healthcare for the population, which will save lives worldwide.

A Legacy of Industry Innovation

Douglas E. Danner, CT(ASCP), founder of Danner Laboratory, graduated from the University of Oklahoma with degrees in Microbiology and Chemistry as well as graduating from the OU School of Cytotechnologists. Under his leadership, Danner Laboratory was founded in San Diego, USA . The laboratory focused on test result accuracy, fast turnaround time and reliable service. Danner Laboratory quickly built a strong reputation for being a trusted partner of gynecology groups and clinics in the San Diego regions.

In 2015, Danner Laboratory was acquired by General Biologicals Corporation (“GBC”), a diagnostic product manufacturer based in Taiwan. GBC added additional testing capabilities including molecular testing and immunoassays, and expanded the business operations to Canada with a new lab in Greater Vancouver, Canada (“Danner Laboratory, Vancouver” or “Danner Lab”). The new lab was provisionally accredited by the College of Physicians and Surgeons of BC under the Diagnostic Accreditation Program (“DAP”) in June 2022.
