The reference values of the complete blood count generally vary according to the sex and age of the patient, however, it is also possible to observe differences in the values depending on the laboratory where the collection was performed.
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.
Usually there is 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 exam because he must take the symptoms into account that the individual presents.
Children's Erythrogram
The following table indicates the erythrogram reference values in children:
| Reference Values for Newborns | Baby reference values up to 1 year | Child Reference Values | |
|---|---|---|---|
| Erythrocytes | 4.0 to 5.6 million/ µL | 4.0 to 4.7 million/ µL | 4.5 to 4.7 million/ µL |
| Hemoglobin | 13.5 to 19.6 g/dL | 11.0 to 13.0 g/dL | 11.5 to 14.8 g/dL |
| Hematocrit | 44 to 62% | 36 to 44% | 37 to 44% |
| VCM | 77.0 to 101.0 fL | 77.0 to 95.0 fL | |
| HCM | 28.0 to 33.0 pg | 30.0 to 33.0 pg |
Female blood count
The following table indicates the reference values of the blood count in women:
| Reference values of women | |
|---|---|
| Erythrogram | |
| Red cells | 3.9 to 5.4 million/ µL |
| Hemoglobin | 12.0 to 16.0 g/dL |
| Hematocrit | 35 to 47% |
| VCM | 80.0 to 100.0 fL |
| HCM | 27.0 to 32.0 pg |
| CHCM | 31.0 to 36.0 g/dL |
| RDW | 10.0 to 16.0% |
| Leucogram | |
| Total leukocytes | 4000 to 11000/ µL |
| Rod Neutrophils | 0 to 800/ µL |
| Segmented Neutrophils | 1600 to 8000/ µL |
| Lymphocytes | 900 to 4000/ µL |
| Monocytes | 100 to 1000/ µL |
| Eosinophils | 0 to 500/ µL |
| Basophiles | 0 to 200/ µL |
| Platelets | 150 000 to 450 000 µL |
CBC in pregnancy
In the case of pregnant women, the WBC may show different normal reference values according to the trimester of pregnancy and the age of the woman, with variation in the normal number of white blood cells. See what are the leukogram reference values in pregnancy.
In relation to the red series, there is no change in the reference values, however it is common to see changes in the levels of red blood cells and hemoglobin, due to the greater need for oxygen supply to the baby and blood hemodilution, It is important that these parameters are evaluated by the physician and the need to initiate appropriate treatment is verified.
Men's blood count
The following table indicates the reference values of the blood count in men:
| Reference Values | |
|---|---|
| Erythrocytes | |
| Red cells | 4.2 to 5.9 million/ µL |
| Hemoglobin | 13.0 to 18.0 g/dL |
| Hematocrit | 38 to 52% |
| VCM | 80.0 to 100.0 fL |
| HCM | 27.0 to 32.0 pg |
| CHCM | 31.0 to 36.0 g/dL |
| RDW | 10 to 16% |
| Leucogram | |
| Total leukocytes | 4000 to 11000/ µL |
| Rod Neutrophils | 0 to 800/ µL |
| Segmented Neutrophils | 1600 to 8000/ µL |
| Lymphocytes | 900 to 4000/ µL |
| Monocytes | 100 to 1000/ µL |
| Eosinophils | 0 to 500/ µL |
| Basophiles | 0 to 200/ µL |
| Platelets | 140 000 to 450 000 µL |
Change results
To interpret the results of the complete blood count, it is necessary to consult the doctor who ordered the exam, because not always that there is a change in the exam values it means that there is a he alth problem.
When there is any change in the results of the blood count, it is important that the doctor evaluates the person, taking into account the symptoms they present and the results of the other tests requested. Often, although there is a slight change in one of the blood count values, this does not necessarily represent a he alth problem. Learn how to interpret blood count results.
