Background: Animal models are widely used in scientific research because of the ability to generate information from an organism like everything under a given experimental condition. Hematological and biochemical tests in laboratory animals are essential for the validation of several scientific studies. In addition, it standardizes physiological values for these animals according to their sex, age, lineage, environment, and nutritional status. The present work aims to establish reference values for biochemical and hematological standards in Balb/c mice, for males and females.Materials, Methods & Results: A total of 50 male and female mice were used at reproductive age. The procedures for collecting, processing, and analyzing the samples were standardized. The collected blood samples were immediately transferred to eppendorf tubes containing heparin, and intended for hematological and biochemical evaluation. The hematological evaluation consisted of Red blood cell count (RBC), Leukocyte counts (WBC), Platelet counts (PLT), Hematocrit (HCT), Hemoglobin concentration (HGB), Mean corpuscular volume (MCV), and Mean corpuscular hemoglobin concentration (MCHC). Already the quantified biochemical parameters were: urea, creatinine, alanina aminotransaminase (ALT), aspartato aminotransaminase (AST) and fosfatase alcalina (FAL). The differential leukocyte count was also performed. Hematological results obtained for males and females were: 9.19 ± 3.35 (106/mm³) and 7.3 ± 2.01(106/mm³) of RBC; 35.8 ± 6.7% and 38.44 ± 3.93% of HCT; 11.51 ± 2.17 g/dL and 11.85 ± 1.56 g/dL of HGB; 45.83 ± 15.03 fL and 60.26 ± 18.25 fL of VCM; 31.80 ± 1.15% and 31.88 ± 0.99% of MCHC; and, 5380 ± 1994.21(10³/mm³) and 3564 ± 1071(10³/mm³) of WBC. The platelet counts were 878.92 ± 84.19 and 678.28 ± 227.21, for males and females respectively.[...](AU)
