About thirty years ago, these instruments were used to study several thousands of blood samples of unselected donors thus defining the reference interval of platelet count as 150450 or 150400109/L.4,5 These values are still used today in most Western countries, although in the meantime several studies have indicated that platelet count varies according to age, sex and ethnicity. 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.

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. In order to determine the most favorable normal range for a specific group of people, there are aspects that must be considered.

Thrombocytopenia might occur as a result of a bone marrow disorder such as leukemia or an immune system problem. Conversely, more than 10% of inhabitants older than 60 years had platelet counts of less than 150109/L in isolates with lower mean platelet counts, while this proportion was reduced to 4.5% in isolates with higher mean platelet counts. A platelet level of less than 150,000/mcL is considered low. The National Heart, Lung, and Blood Institute notes that higher-than-usual platelet counts may indicate thrombocythemia or thrombocytosis.

In conclusion, it is suggested that introducing the new platelet count ranges into clinical practice would reduce the number/proportion of normal individuals unduly considered at high risk of all-cause mortality and would be useful to better identify those subjects at higher mortality risk, possibly related to a low platelet count. Medications can reduce normal blood platelets. There is some lab-to-lab variability in ranges due to differences in equipment, techniques, and chemicals used.

What if I have a low platelet count? Ben Elwood (WCVM) Healthy adults usually have between 150 billion and 450 billion platelets in every litre of blood. Before Further studies are required to confirm that these reference intervals better distinguish subjects with diseases affecting platelet count from healthy people. However, a 2014 review suggests. These reference intervals are shown in Figure 2. Normal hemoglobin levels of women: 12.3 - 15.3 g/dL (average is 13.8 g/dL) Other lab tests results may have a slightly different normal range for hemoglobin levels. For men, the average is between 135,000 and 317,000 per microliter of blood. WBC counts vary diurnally, with counts being lowest in the morning and highest in the late afternoon. While it is unknown if these numbers are representative of all populations, the review authors indicate there have been similar platelet observations in the United States and different African populations: More recent data from a Swiss 2020 study on an aging population found that platelet count by age remained predominantly stable for females and saw an overall decline for males: It is not clear why platelet ranges change with age. The Platelet counts can show a normal increase at high altitudes, after strenuous exercise, and in the winter.

However, many people who have a high platelet count do not have symptoms at all. This is well exemplified by Sardinian geographic isolates where different genetic backgrounds are responsible for large differences in mean platelet counts in different areas.9 The percentage of healthy people under the age of 18 years with platelet counts over 400109/L was 11% in the isolates with higher mean platelet counts, while it was less than 4% in the isolates with lower mean platelet counts. about navigating our updated article layout. However, if there's any slight difference, that may still be considered normal because some laboratory tests use different ways to measure platelet count.
