what is a normal range for hemoglobin

The normal range for hemoglobin levels varies depending on age, sex, and other factors. Here are the general guidelines:

• Adult Men: 13.8 to 17.2 grams per deciliter (g/dL)
• Adult Women: 12.1 to 15.1 g/dL
• Children: The range can vary significantly depending on age, so it's best to consult a pediatrician.

Hemoglobin levels outside these ranges may indicate conditions such as anemia or polycythemia. Always consult with a healthcare provider for a proper diagnosis and treatment plan.
