Platelet counts between 150 x 10(9)/l and 400 x 10(9)/l are considered as normal in the adult population. However in Spain it is not unusual to find lower counts in healthy people.


We have studied platelet counts in 1,430 prospective healthy platelet donors. In 93 we measured mean platelet volume (MPV) in a blood sample collected in citrate (1:4 v/v) in order to avoid the platelet swelling induced by EDTA. Complete blood counts were performed on a Bayer-Technicon H*1. A reference range of 95% was calculated for platelet count and MPV, and the relationship between platelet count and sex, age, hemoglobin and MPV was studied.


Mean (SD) platelet count (in x 10(9)/l) in men (195 [42]; n = 1,053) is lower (p < or = 0.0005) than in women (213 [47]; n = 377). The reference range in men is 123-295, in women 137-319 and in both 125 to 300. The mean (SD) for MPV (in fl) is 9.6 (0.7) (no significant differences between sexes) and the reference range is 7.8-11. There is an inverse linear relationship between the circulating platelets and their MPV measured in citrate at high concentration (r = -0.282, p = 0.006, n = 93) and in EDTA (r = -0.364, p < or = 0.0005, n = 1,430) and also between platelet count and Hb levels (r = -0.166, p < or = 0.0005).


The mean of platelet count in women is higher than in males in a sample of Spanish population. There is an inverse linear relationship between platelet count and their MPV measures measured in citrate at high concentration and in EDTA. The reference range for platelet count seems to be lower than in other populations of North European origin.
