Question
What are the normal hemoglobin and hematocrit levels for a 4-year-old child? What should be done if the test results are abnormal?
Answer
Hello, the reference range for hemoglobin in children does not vary with age and is consistent with adults. The normal hemoglobin range for children is 120-160g/L, and adults have gender differences, whereas children do not. Therefore, the reference range for all childhood hemoglobin is based on this standard. As for hematocrit, a level below 110 grams per liter is considered abnormal for children aged from 6 months to 6 years. It is recommended that you refer to the specific test results for comparison.
