What is B-Hb?

B-Hb, or beta-hemoglobin, refers to the beta chain of hemoglobin, the protein in red blood cells responsible for transporting oxygen throughout the body. Hemoglobin is composed of four polypeptide chains: two alpha and two beta chains. Variations or mutations in the beta chain can lead to hemoglobinopathies, such as sickle cell disease and beta-thalassemia, which can affect oxygen delivery and overall health. Understanding B-Hb is crucial for diagnosing and treating these blood disorders.
