Overview. Why is hemoglobin a1c important? What is a hemoglobin test? A hemoglobin test measures the amount of hemoglobin in your blood. Hemoglobin is a protein that’s the main component of red blood cells (erythrocytes). Hemoglobin contains iron, which allows it to bind to oxygen.
Summary. Hemoglobin is an iron-rich protein in red blood cells that enables the blood to carry oxygen to tissues throughout the body. Low hemoglobin levels often indicate anemia, but high levels...
A hemoglobin test measures the amount of hemoglobin (Hb or Hgb) in your blood. This protein in your red blood cells (RBCs) carries oxygen and carbon dioxide between the lungs and the rest of the body. An altered hemoglobin level is often a sign of disease. Without the right amount, your body may not have enough energy to function optimally.
Normal RBC Reference Range. An RBC count is the number of red blood cells per a particular volume of blood. It may be reported in millions of cells per microliter (mcL) of blood or in trillions of cells per liter (L) of blood. The normal RBC count (also known as the reference range) varies by sex and age: Adult females: 4.2 to 5.4 million/mcL.
