There is no proven explanation for these age-related changes, although it may be that the sharp decrease in platelet count during infancy reflects the decline of thrombopoietin levels occurring from birth to adulthood.13 Concerning the mechanism of platelet reduction in old age, it has been suggested that it derives from a survival advantage of subjects with lower platelet counts or a reduction in hematopoietic stem cell reserve during aging.12 However, both these explanations are purely hypothetical, and further investigation is required to clarify this matter. doi: https://doi.org/10.1182/blood-2016-01-692814, Platelet count has been reportedly associated in a nonlinear way with a number of health outcomes among older subjects1,2 or in high-risk groups.3 One early study has investigated the involvement of platelet count for cardiovascular mortality in a general middle-aged population of healthy men.4, Platelet count decreases during aging, is higher in women than in men,5,6 and varies in populations of different origin.6,7 More recently, it has been reported that platelet count is also influenced by dietary habits.8.

This article discusses platelets in more detail and the expected platelet count based on a persons age. Therefore, with a total of 70 PLTs per 1,000 RBCs and a RBC count of 4.10 x 10 12 /L, the calculations would be: RBC count/1,000 = 4.10 x 10 9 /L. Although the new reference intervals have not yet been used in clinical practice, they are expected to reduce the number of older subjects, especially men, who receive an undue diagnosis of mild thrombocytopenia, as well as the number of children with undue diagnosis of mild thrombocytosis. Nagata Y, Yoshikawa J, Hashimoto A, Yamamoto M, Payne AH, Todokoro K. Proplatelet formation of megakaryocytes is triggered by autocrine-synthesized estradiol. Compared with subjects included in the normal platelet count category for both criteria, those who shifted from thrombocytopenia, as defined by the usual ranges (<150 109/L), to normal platelet count according to the new ranges (n = 278; n of deaths = 50) had a risk of death of 1.37 (95% CI, 1.02-1.85).

The cohort was followed up until May 2015 with the main outcome of interest being all-cause mortality. Subsequent studies confirmed that females have a slightly higher platelet count.7,8,14 The already mentioned studies of different Italian populations further supported this conclusion and precisely defined sex-related differences in relation to aging.912 In particular, no difference in the platelet count of men and women was found before the age of 15 years, whereas women had more platelets than men in the age range 1564 years and over 64 years.12 In any case, sex-related differences in adults were only approximately 10% and much lower than those related to aging.
