Profile page(s)
Dr Nathan Brendish is a NIHR Clinical Lecturer in Infectious Diseases & General Internal Medicine. His research interests focus on the clinical impact of point-of-care testing for infectious diseases.
Dr Brendish started his research career as a study physician in the NIHR Southampton Clinical Research Facility, working on malaria vaccine trials. He has led several molecular point-of-care testing clinical trials within Professor Tristan Clark’s research group resulting in multiple publications in Lancet series journals among others. He was seconded to Public Health England, and later NHS Test and Trace, for several months in response to the COVID-19 pandemic.

Impact example:
Based on the work of Dr Brendish and others within Professor Tristan Clark’s group, molecular point-of-care testing for COVID-19 has now become the standard-of-care for patients admitted to Southampton General Hospital’s Acute Medicine Unit. Similarly, the FebriDx fingerprick point-of-care testing device has become a powerful triage tool, used as standard-of-care in Southampton’s Emergency Department.
