Hemostatic, hematological, and chemical parameters were determined in 25 captive Arabian oryxes (Oryx leucoryx) of both sexes. Hemostatic parameters included prothrombin time, activated partial thromboplastin time, fibrinogen, and clotting factors activities. Serum concentrations of 26 biochemical and inorganic constituents were determined along with hematological data, namely platelet counts, platelet indices, and red and white blood cell variables. Hemostatic parameters, platelet indices, and many biochemical components are reported for the first time in the Arabian oryx. Relatively low mean platelet volume, plateletcrit and platelet distribution width, and relatively short prothrombin and activated partial thromboplastin times and high platelet counts, and F:VIII clotting activity were recorded in the oryx. Most of the basic hematological and biochemical parameters recorded in this species were consistent with other wild bovidae.
