About us - Cavidi

A new game-changing signal amplifier in the lab.Translates to new hope in the clinic.

Introducing Exazym®

A history of innovation, access, and empathy

How we started
In 1984 two determined virologists from Uppsala University founded Cavidi to make disease diagnostics and monitoring more accessible globally.

Their work began with the search for novel biomarkers for HIV. This led to the world’s first viral load monitoring kit that provided the accuracy of PCR without the expense, expertise, or equipment.

Discovery through adversity
Faced with the COVID-19 pandemic in 2020, our virologists saw the need for an easily deployed yet highly accurate diagnostic test. This work led to the discovery of BOLD (binding oligo ladder detection) — a novel immunoassay signal booster that can be used to increase the sensitivity of virtually any type of immunoassay by a factor of up to 100 times. Branded Exazym®, it was successfully trialed on the SARS-CoV-2 virus and now is being tested on a number of challenging biomarkers.

Biomarker breakthrough
Exazym® is a game-changer in biomarker detection. It makes highly reliable, incredibly sensitive detection accessible to all researchers and clinicians globally, requiring no specialized equipment or training. In the lab this will help translational researchers and drug development teams get to market sooner with life-saving innovations. In the clinic, Exazym® will directly improve patient outcomes through much earlier detection and diagnosis of disease than current methods permit.

Detection democratized

Help amplify our message

Quality diagnostics and monitoring are foundational for good health. However, all too often the “gold standard” test is too expensive or complicated for many clinics and patients.

For diagnostic and monitoring tools, the term “gold standard” has become a myopic accolade. It rightly celebrates the technical accuracy of the test but completely ignores access. What many see as a “gold standard” Cavidi sees as a starting point. Until a test has achieved both high accuracy and high access, it gets bronze in our book.

Cavidi develops innovative solutions for translational researchers and clinics. Our work helps them provide patients with greater access to accurate diagnostics and monitoring. Our latest breakthrough is Exazym® — a game-changer in biomarker detection. It makes highly reliable, incredibly sensitive immunoassay signal amplification accessible to all researchers and clinicians globally.
