Background: Aging refers to the natural and inevitable process of growing older over time. The present study was conducted to assess variations in platelet parameters in the geriatric age group. Materials & Methods: 500 subjects aged >65 years of both genders were selected. 2 groups were made. Group I were 500 subjects (aged >65 years) and group II was healthy control 505 subjects (aged 20-30 years). 5 ml venous blood was taken in a test tube, and a platelet count and MPV was assessed with a 5-part hematology analyser. Results: Out of 500 patients, males were 280 and females were 220. The mean platelets count in males was 184.2 X109/l and in females was 225.4 X109/l. The mean MPV was 10.4 Fl in males and 10.9 FL in females. The difference was significant (P< 0.05). The mean platelets count in group I was 206.7 X109/l, and in group II was 218.4 X109/l. The mean MPV was 10.3 Fl in group I and 10.8 FL in group II. The difference was non-significant (P< 0.05). Conclusion: There is no statistically significant difference between the young adult control group and the healthy old population in terms of platelet volume and count. Therefore, it is not required to have distinct values for mean platelet volume and platelet count in the elderly.
