Diagnostic sensitivity

The figure below presents all the results from studies in which the diagnostic sensitivity was actually reported. The number of occurrences for each diagnostic test is reported in square brackets. Please note that the range of values might refer to different target species.

Diagnostic specificity

The figure below presents all the results from studies in which the diagnostic specificity was actually reported. The number of occurrences for each diagnostic test is reported in square brackets. Please note that the range of values might refer to different target species. 

Summary of available data

Below you can find a summary of the main features of each study:

• RefID: Reference ID (to be used to retrieve full reference below)
  
• Species: in which animal species the diagnostic assays have been tested
  
• Target: Antigen, Antibody, Nucleic acid or Virus
  
• Lab test: type diagnostic assays evaluated in the study
  
• Study type: Cohort, Cross-sectional, Diagnostic test validation, Longitudinal
  
• Nr tested: number of samples tested within the study. When multiple groups were tested, the range of sample sizes is reported
  
• Nr positive: number of samples that tested positive. When multiple groups were tested, the range of positive results is reported
  
• Se: whether an estimate of diagnostic test sensitivity was reported in the article
  
• Sp: whether an estimate of diagnostic test specificity was reported in the article
