Hemoglobin is the common name for what is clinically known as hemoglobin. There is no clear standard value for hemoglobin in children, and it varies with age, >110g/L before 6 years of age, and >120g/L between the ages of 6 and 12.
Hemoglobin is the active component of human blood, accounting for 97% of the total red blood cells. Hemoglobin measurement can be used to diagnose anemia or assess the effectiveness of treatment for blood disorders, and in addition, hemoglobin helps the body to transport oxygen, carbon dioxide, and so on.
Children’s hemoglobin is 150~220g/L at birth, then drops to about 100g/L at 2~3 months of age, then slowly increases to >110g/L before 6 years of age, >120g/L at 6~12 years of age, and reaches the adult level at 12 years of age.
A low result may indicate that the child has an anemic disorder, and a high result may indicate that the child has a disorder such as true erythrocytosis. However, the results of one test alone cannot confirm the diagnosis of a disease, and it is necessary to go to the hospital, complete other related tests, and combine the results of other tests to make a judgment.
