New sepsis test for doctors

In 2025, we launched a simple, new, 10 minute test for researchers, doctors and hospital labs to help with the diagnosis of sepsis. The imiwn sTLR2 RAPID test was developed at our R&D lab in North Wales, and shows potential for providing additional insights into inflammation and sepsis compared with traditional biomarkers such as CRP.
