Tuberculosis (TB) in small ruminants is a neglected disease despite its major impact on goat and sheep production and the global public health. The awareness of the role of small ruminants in the epidemiology of animal TB has increased in the last two decades, however, there is a lack of standardization of procedures and robust quantitative estimates on the accuracy of diagnostic TB tests in the scientific literature. To address this knowledge gap, all the available information regarding the use of ante-mortem diagnostic techniques in small ruminants was collected and summarized through a systematic review process. Furthermore, a random-effects meta-analysis was conducted to separately estimate the sensitivity (Se) and specificity (Sp) of cell-based tests among the retrieved studies in goats. Studies included in the meta-analysis were also evaluated using the Quality Assessment of Diagnostic Accuracy Studies included in systematic reviews adapted for animal diagnostic tests (VETQUADAS). Median pooled Se estimates of the single intradermal tuberculin (SIT) test (ranged from 0.51 to 0.59), the comparative intradermal tuberculin (CIT) test (ranged from 0.30 to 0.50) and the interferon-gamma (IFN-γ) release assay (IGRA) (ranged from 0.66 to 0.72) were lower than that reported previously in cattle, regardless the interpretation criteria and the reporting of MAP infection or vaccination. However, the specificity was adequate for all the tests (ranged from 0.95 to 0.99), except for the SIT test in MAP vaccinated herds (ranged from 0.78 to 0.90). This study provides an overview of the accuracy of diagnostic tests for TB in goats, however, the considerable between-study heterogeneity found hampered the conclusive interpretation of the pooled Se and Sp estimates. Therefore, further studies in small ruminants are necessary to optimize the diagnostic Se, which could help to design effective control strategies, accelerate the eradication of TB in these species and harmonize test procedures
