Our Story

In 2016 Great North Research & Innovation was founded by a clinician as a research and development company specialising in biotechnology and advanced diagnostics.  GNRI's principal mission is to alleviate the suffering caused by Sepsis and as a company we remain dedicated to that purpose, and to developing effective solutions that improve outcomes for patients.

The GNRI platform provides information that enables clinicians to act rapidly, with the clarity of purpose that comes from peerless sensitivity and specificity: eliminating harmful delays to therapeutic intervention in cases of Sepsis, and in other life-threatening infectious conditions.

At GNRI our specialist team collaborates with key partner organisations to deliver advanced research and development in biotechnology and diagnostics for the benefit of patients all over the world.  Our principal objective is to bring about a step change in the field of medical diagnostics: introducing novel, affordable solutions that offer enhanced speed and accuracy.

From concept development to point-of-care, GNRI exists to enable real-time informed clinical decision-making in high risk scenarios where time and accuracy are critical factors.
