This study investigated some haematological parameters of Primary hypertensive subjects. Objectives: To compare some haematological parameters (haematocrit, haemoglobin concentration, Platelets count, White Blood Cells count, red blood cell count and Red Cells Indices between hypertensive and normotensive subjects. Materials and methods: Blood samples were collected from 76 known hypertensive subjects between 30 - 70 years attending the Cardiology clinic of the University of Abuja Teaching Hospital Gwagwalada. Another 37 normotensive subjects between 30 - 65 years served as the control. All subjects gave their consents. Platelets count, Haemoglobin estimation, Packed Cell Volume, Red Blood Cell Count, Mean Cell Volume, Mean Cell Haemoglobin, Mean Cell Haemoglobin Concentration and White Blood Cell count were determined using Mythic 22 five parts haematology analyzer. Results: Results for Hypertensive and Control subjects were, White Blood Cell, 5.76 ¡À 1.45 ¡Á 10⁹/l and 4.76 ¡À 1.03 ¡Á 10⁹/l, Platelet count, 248.7552.45 ¡Á 10⁹/l and 284.95 ¡À 27.66 ¡Á 10⁹/l, Mean Cell Volume, 91.81 ¡À 3.05 fl and 85.68 ¡À 6.48
