Estimates of the diagnostic specificity (Sp) and sensitivity (Se) of the field IMS-LFD and laboratory-based IMS-qPCR and IMS-culture tests for M. bovis in faeces from 100 live captured badgers and 30 live captive badgers relative to live diagnostic test results, obtained using McNemar’s test (95% confidence intervals are indicated in parentheses)
