The aim of the study was to determine the hematological, biochemical and acid-base equilibrium parameters that could be referential for the population of hares inhabiting Poland. Blood for analysis was collected from 36 clinically healthy adult hares (24 females and 12 males), which were caught alive in their natural environment. The hares were observed for 48 hours to eliminate sick animals from further examinations. Before blood collection the animals were administered a mixture of ksylazyna - 2 mg/kg - and ketamina in the same dose. The following acid-base equilibrium parameters were determined from the arterial blood: pH of blood, pCO₂, HCO₃. The AST, ALT, ALP, concentration of urea, creatinine, cholesterol, triglycerides, glucose, WBC, RBC, HGB, Ht were determined from the venous blood. The concentration of calcium, phosphorus, magnesium, sodium, potassium and chlorides were determined in the blood serum. The mean of the determined parameters was: pH = 7.38, pCO₂ = 41.11 mmHg, HCO₃⁻ = 22.83 mmol/l, AST = 245 U/l, ALT = 124 U/l, ALP = 51.4 U/l, the concentration of urea = 7.2 mmol/l, creatinine = 95.7 µmol/l, cholesterol = 0.55 mmol/l, triglycerides 1.3 mmol/l, glucose = 9.24 mmol/l, WBC = 4.27 U/L, RBC = 9.74 U/L, Hb = 12.5 mmol/l, Ht = 0.58 l/l, Ca²⁺ = 2.55 mmol/l, Mg²⁺ = 1.14 mmol/l, P²⁺ = 1.37 mmol/l, Na⁺ = 146.5 mmol/l, K+ = 3.77 mmol/l, Cl⁻ = 108 mmol/l.
