High quality instrumentation, scalable technology, robotics/laboratory automation and mobile deployment are central to our success. BasisDx operates in an 88,000 square foot facility with a specially created COVID-19 BSL-2 level clean room in Newark, California (SF Bay Area).

Fast, accessible test results without compromising accuracy.

PCR testing is the most sensitive COVID-19 testing method; resulting in fewer false negatives and fewer false positives than antigen. Our mobile lab can offer individual or large-scale testing at almost any location, and our in-house clinical labs run by scientists and physicians under strict CLIA standards. Antigen testing is a great screening tool for employers, schools and other applications with super fast turnaround resulted to your phone.
