Background: Reference hematological values for chelonians are uncommon, especially those that take account of seasonal variations. While there exists controversy over how climate influences hematological values in different reptile species, the identification of this influence would help with the diagnosis, treatment, and prognosis of diseases that affect these species, often kept as pets. Chelonians are ectotherms and, therefore, intrinsic and extrinsic factors may affect physiological and hematological values, affecting the interpretation of clinical information on these species. The aims of this study were to assess the hematological values of captive red-footed tortoises (Chelonoidis carbonaria) and to check their variation according to the cold and warmer seasons of the year. Materials, Methods &Results: Blood samples were collected from nine red-footed tortoises (C. carbonaria) of indeterminate sex and different ages, bred in captivity without control over environmental variables during one year, one each season (summer, fall, winter and spring). A total of 36 samples were considered to study. The colder seasons were collapsed together into one group that holds winter and fall (colds) and the months whit warmer weather spring and summer were grouped as a class called (warm). The complete blood count was performed manually, and medians, maximum values, and minimum [...](AU)
