The reference values of the complete blood count generally vary according to the patient's sex and age, however, it is also possible to observe differences in the values depending on the laboratory where the collection was made.
The blood count is used to evaluate certain blood aspects such as the number of red blood cells, leukocytes and platelets, being a good way to identify the presence of infections, excess iron or anemia, for example.
There is usually a sign of infection when there is an increase in leukocytes and there are signs of allergy when there is an increase in eosinophils, but it is important that the interpretation of the blood count is done by the doctor who ordered the test because it must take into account the symptoms that the individual has.

Complete blood count in pregnancy
In the case of pregnant women, only the leukogram has different values, as they vary according to the trimester of pregnancy and the woman's age, with variation in the normal number of white blood cells. See what the leukogram reference values in pregnancy are.

Change of results
In order to interpret the results of the complete blood count, it is necessary to consult the doctor who ordered the test, as not always when there is a change in the test values it means that there is a health problem.
When there is any change in the results of the blood count, it is important that the doctor assesses the person, taking into account the symptoms he presents and the results of the other tests ordered. Often, although there is a slight change in one of the blood count values, this does not necessarily represent a health problem. Learn how to interpret your blood count results.
