The reference values of the blood count may vary according to the method of analysis used by the laboratory, according to the person's age, gender and whether the woman is pregnant. In this way, the results of hemogram are always accompanied by the reference values of the laboratory where it was performed (described on the right side of the results sheet).
In general, the blood count reference values are:
Hematocrit (%)
- Women (35 - 47)
- Men (40 - 54)
- Pregnant women (34 - 47)
- Children aged 10 to 12 years (37 - 44)
- Children 1 year (36 - 44)
- Children 3 months (32-44)
- Term newborns (44-62)
Erythrocytes (millions / mm³)
- Women (4.0 - 5.6)
- Men (4.5 - 6.5)
- Pregnant women (3.9 - 5.6)
- Children aged 10 to 12 years (4.5 - 4.7)
- Children of 1 year (4.0 - 4.7)
- Children aged 3 months (4.5 - 4.7)
- Term newborns (4.0 - 5.6)
Hemoglobin (g / 100ml)
- Women (12 - 16.5)
- Men (13.5 - 18)
- Pregnant women (11.5 - 16.0)
- Children aged 10 to 12 years (11.5 - 14.8)
- Children of 1 year (11.0 - 13.0)
- Children aged 3 months (9.5 - 12.5)
- Term newborns (13.5 - 19.6)
Mean corpuscular volume - VGM (μ³)
- Women (81 - 101)
- Men (82 - 101)
- Children aged 10 to 12 years (77 - 95)
- Children 1 year old (77 - 101)
- Children aged 3 months (83 - 110)
Mean corpuscular hemoglobin - HbCM (pg)
- Women (27 - 34)
- Men (27 - 34)
- Children from 10 to 12 years old (24 -30)
- Children of 1 year (23 -31)
- Children 3 months (24-34)
Concentration of corpuscular hemoglobin - CHbCM (%)
- Women (31.5 -36)
- Men (31,5 -36)
- Children from 10 to 12 years old (30 -33)
- Children 1 year (28 - 33)
- Children aged 3 months (27-34)
Platelets
- 150,000 to 400,000 (μl)

A blood count is the test that looks at the quantity and quality of blood cells. The results, on their own, may not be sufficient to provide a diagnosis, so they should be analyzed and interpreted by the physician in conjunction with the patient's clinical examination.
