Liver disease develops silently and presents late with end-stage disease; as a result, one-third of new admissions die within the first few months, and death rates have doubled in the last 15 years.

The Southampton ‘traffic light’ calculator is a test for liver disease suitable for community use that could enhance assessment of liver risk and allow rational referral of more severe disease to specialist care.

The algorithm used within this calculator only works with assays done by University of Southampton University Hospital Trust. It must NOT be used with individual test results from other hospitals.
