What is the normal range for hemoglobin in the blood?

The normal range for hemoglobin in the blood for healthy adults typically falls between 12 and 18 grams per deciliter (g/dL). Hemoglobin is a crucial protein found in red blood cells that carries oxygen throughout the body. Levels below this range may indicate anemia, while levels above it could suggest conditions such as polycythemia.

It is important for individuals, especially those in the medical field, to recognize this range as it helps inform assessments of a person's oxygen-carrying capacity and overall health. Understanding the normal hemoglobin levels is essential for diagnosing and managing various medical conditions effectively.
