Full blood count normal reference values for adults in France

Aims

To determine full blood count (FBC) normal reference values for adults.

Methods

FBC normal values for healthy adults were defined, after establishing preanalytical conditions, in a population of 33 258 subjects, 19 612 men and 13 646 women. The values were established after excluding from this population all people having conditions liable to modify, directly or indirectly, FBC parameters.

Results

Results for values of standard parameters are provided in detail for each parameter, by sex and by age group from 16 to 69 years of age. In addition, we present FBC values from a population of 339 subjects aged over 69 years with no comorbidities.

Conclusions

These normal values are proposed for use in everyday practice. They make it possible to distinguish, without ambiguity, a normal situation from a pathological situation. Moreover, they might be used over all mainland France.
