Objective: To analyze the parameters that can facilitate the differential diagnosis of brucella epididymorchitis (BEO) and non-brucella epididymorchitis (NBEO) and to facilitate early diagnosis. Material And Methods: The data of 23 BEO patients and 80 NBEO patients, who applied in a tertiary center in eastern Turkey, where brucellosis is common, were retrospectively analyzed. Age, hemogram parameters (white blood cell (WBC)), neutrophil, lymphocyte, monocyte, eosinophil, basophil, platelet, neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), mean platelet volume (MPV), red blood cell distribution width (RDW), biochemical parameters (aspartate transaminase and alanine aminotransferase), inflammatory markers (C-reactive protein, erythrocyte sedimentation rate, and procalcitonin), urine culture, and scrotal doppler ultrasound findings were analyzed retrospectively and were compared between BEO and NBEO groups. Results: In the comparison of the BEO and NBEO groups, there was a significant difference between the two groups in WBC count, neutrophil count, monocytes count, NLR, MLR, MPV, and procalcitonin levels (p = 0.035, p = 0.007, p = 0.003, p = 0.005, p = 0.01, p < 0.001, p < 0.001, respectively). Conclusions: The NLR may be promising for use in the early diagnosis of BEO. The MPV also drew attention as parameters that can be evaluated
