normal platelet count by age chart

The inappropriateness of the single limit of 150109/L to define thrombocytopenia is also supported by the results of a study that monitored for five years 191 apparently healthy adults with incidentally discovered platelet counts between 100 and 150109/L.21 In the vast majority of cases, the degree of thrombocytopenia remained stable without the appearance of any disease, and the authors concluded that the risk of developing severe thrombocytopenia in this category of patients was low.

Advancing postnatal age had a significant effect on platelet counts; during the first 9 weeks, the counts fit a sinusoidal pattern with two peaks; one at 2 to 3 weeks and a second at 6 to 7 weeks. Male: 4.35 trillion to 5.65 trillion cells/L. You will also learn what causes platelets to go out of the normal range, as well as how these conditions can be treated.

U-shaped mortality curve associated with platelet count among older people: a community-based cohort study. It is, therefore, appropriate to discuss whether a single reference interval for all people is still valid or whether new normal ranges taking into account these variables have to be used in clinical practice. However, bone marrow changes, vascular aging, and changes in blood composition over time may all affect how many platelets are in the bloodstream.
