Hemolysis refers specifically to the breakdown or destruction of red blood cells (erythrocytes). During this process, hemoglobin is released from the red blood cells into the surrounding fluid, which can result in various physiological effects and can be measured in blood tests. Hemolysis can occur naturally as part of the body's process of clearing old or damaged red blood cells, but it can also happen due to other factors, such as certain medical conditions, infections, or reactions to blood transfusions.
Understanding hemolysis is essential for laboratory professionals, as it can affect blood test results, such as those measuring hemoglobin levels or other components that get altered when red blood cells are broken down. This process is distinct from other biological functions, such as nutrient absorption, white blood cell production, or clot formation, each serving very different roles within the body.
