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. Using personalized (sex- and age-specific) rather than traditional reference intervals of platelet count reduces the number/proportion of subjects with thrombocytopenia, as lately observed in a sample of Italian adult patients to whom the newly identified cutoffs were applied.11.

Thrombocytopenia ( platelets in peripheral blood) may result from a variety of causes: artifact (clumping during collection, iatrogenic hemodilution), congenital (inherited macrothrombocytopenia), decreased platelet production in bone marrow (drugs, neoplasia, infections), increased consumption of platelets in coagulation (DIC), increased destruction of platelets (primary or secondary immune-mediated thrombocytopenia), and loss of platelets (acute massive hemorrhage). Analysis of 12,517 inhabitants of Sardinian geographic isolates found that a 10-year increase in age corresponded to a 9109/L decrease in platelet count.9 Very similar results were obtained in 7266 inhabitants of five additional geographic isolates located in different Italian areas10 and in the cohort of the Moli-Sani Project including 24,318 subjects from 30 Molise cities and villages.11 Finally, a recent study put together all data of subjects enrolled in the three population-based studies referenced above and concluded that age-related changes were actually very large: platelet count in old age was reduced by 35% in men and by 25% in women with respect to early infancy.12 As shown in Figure 1, most of this reduction occurred in childhood and in old age, with only minor changes in adulthood.

Platelets count of a child in the age 6 and 7 years should be between (176-452) to be normal count and exclude thrombotic diseases related to platelets deficiency. Thrombocytopenia may be caused by either of two different processes that cause a reduction in the count . One Blood. A great majority of epidemiologic studies still relies on the use of single reference intervals regardless of age and sex differences in platelet count.9 Similarly, most laboratories in western countries still adopt standard ranges for classification of thrombocytopenia or thrombocytosis (generally 150-400 or 450 109 platelets/L for all people). Patients with platelet counts greater than 50 10 3 per L rarely have symptoms. The size of platelets is referred to as the mean platelet volume (MPV).
