The University Hospitals Bristol NHS Foundation Trust in the UK will conduct an independent review of 3,500 cancer tests following claims that 15 histopathology patients were misdiagnosed at the hospital in 2000–2008.

The Trust will carry out a ten-week long audit of cases from 2007 to find out the rate of errors, on the advice of Royal College of Pathologists.

Each case will be checked by two independent specialist pathologists to establish if there is a significant error rate and identify any areas of concern, the Trust said.

Pathology and histopathology are complex areas where differences of opinion and interpretation between reporting doctors can arise, according to the Royal College of Pathologists.
