Introduction: Hematologists have always had a keen interest in researching the pathophysiology and clinical relevance of hematological parameters in various populations. Factors that may affect hematological and serum biochemical parameters might include gender, age, body mass index (BMI), season, and nutrition. Aim: The aim of this study was to determine the association of hemoglobin, red blood cell (RBC) count, white blood cell (WBC) count, and platelets with the age, gender, and BMI of patients who came to the hematology section of the department in the regular outpatient department (OPD) services. Materials and Methods: We had selected 300 patients randomly who came to the hematology section of the department in the regular OPD services. We had calculated height and weight of the patient after their consent and calculated their BMI. The selected patients were categorized into five age groups from Group A to Group E (20–30 years, 31–40 years, 41–50 years, 51–60 years, and 61–70 years), into males and females (Group A and Group B), also according to BMI into four groups (Group A – BMI <18.5 kg/m2, Group B – BMI <18.5–25 kg/m2, Group C – BMI >25 kg/m2, and Group D – BMI >30 kg/m2). Blood sample was collected from each patient in an ethylenediaminetetraacetic acid anticoagulant and was analyzed using a hematological autoanalyzer. Results and Discussion: A decline in hemoglobin (HB) levels and RBC count was observed above 30 years, and it decreased more in females. The mean age of obese subgroup was found to be significantly more among males. Whereas, underweight and overweight were found to be significantly more among females. HB, RBC, and platelet count did not show any significant difference among the subgroups of BMI category, but WBC count was found to be adequate in majority of the subjects with normal weight. Conclusion: In our study, we found an age-dependent decline in HB levels in the age group above 30 years. RBC and platelet count did not show any significant difference among the subgroups of BMI category, but WBC count was found to be adequate in subjects with normal weight.
