Platelet count measures the number of platelets in a volume of blood and usually ranges between 150,000 to 400,000 per cmm. Normal Range Platelet count normally ranges from 150 - 450 thousand cells/uL (thousand cells per microliter) [ 5 ]. The standard counts have remained at the broad range of 150,000450,000 platelets/mcL of blood. The mean platelet count was higher in women than men in all age classes, although the differences were small (approx. Platelet count and the risk for thrombosis and death in the elderly. Platelets are tiny blood cells. 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. 4,500 to 11,000 for women.

The cohort was followed up until May 2015 with the main outcome of interest being all-cause mortality. 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. Critical Values Platelets (PLT) < 30,000/CMM or >1,000,000/CMM Results.

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. In conclusion, there is little doubt that a new reference range taking into account these variables would be desirable to identify more accurately subjects with platelet disorders. Subjects with platelet counts within the reference intervals have to be considered normal, while those with platelet counts outside this range but within the extended one are in a gray area that is still compatible with a normal phenotype, but also with mild forms of thrombocytosis or thrombocytopenia.

Gestational Diabetes Melitus and Cord Blood Platelet Function Studied via the PFA-100 System. 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.

The purpose of platelets is to create hemostasis, which is the prevention of hemorrhaging and the process of keeping blood inside the vessel walls. A person's risk of bleeding starts to go up when their platelet count is less than normal. Several studies showed that platelet count is highly heritable,14 and a few genetic factors responsible for platelet count variability in healthy individuals have been identified.19 The importance of genetic background in regulating the concentration of platelets is well illustrated by a recent study of five geographic isolates in Italy,10 where mean platelet count in healthy inhabitants of different areas ranged from 220 to 265109/L. A platelet count is a quick, common test that measures how many platelets are in your blood.
