What is the rupturing of blood cells?
Hemolysis or haemolysis (/hiːˈmɒlɪsɪs/), also known by several other names, is the rupturing (lysis) of red blood cells (erythrocytes) and the release of their contents (cytoplasm) into surrounding fluid (e.g. blood plasma). Hemolysis may occur in vivo or in vitro (inside or outside the body).
What is the medical term for rupture of red blood cells?
Red blood cell lysis is more commonly known as hemolysis, or sometimes haemolysis. Image Credit: PhonlamaiPhoto/Shutterstock.com. It refers to the process whereby red blood cells rupture and their contents leak out into the bloodstream.
What is red blood cell hemolysis?
Hemolysis is the destruction of red blood cells. Hemolysis can occur due to different causes and leads to the release of hemoglobin into the bloodstream. Normal red blood cells (erythrocytes) have a lifespan of about 120 days. After they die they break down and are removed from the circulation by the spleen.
Where does hemolysis occur?
Red blood cells develop in the bone marrow, which is the sponge-like tissue inside your bones. Your body normally destroys old or faulty red blood cells in the spleen or other parts of your body through a process called hemolysis.
What is severe anemia called?
This type of anemia is called “pernicious” because it was once considered a deadly disease. This was due to the lack of available treatment.
What causes hemolysis during blood draw?
Hemolysis resulting from phlebotomy may be caused by incorrect needle size, improper tube mixing, incorrect filling of tubes, excessive suction, prolonged tourniquet, and difficult collection.
How do you prevent hemolysis?
Best Practices to Prevent Hemolysis
- Use the correct needle size for blood collection (20-22 gauge).
- Avoid using butterfly needles, unless specifically requested by patient.
- Warm up the venipuncture site to increase blood flow.
- Allow disinfectant on venipuncture site to dry completely.

What happens when hemoglobin bursts in the blood?
Hemoglobin is also what makes blood red. So naturally, when red cells burst, it tinges the liquid portion of the blood. If red cells burst during specimen collection, the blood being tested is not the same as the blood circulating in the patient. It’s as different as night and day.
How are red blood cells destroyed in hemolysis?
But before we master the art of preventing hemolysis, we have to understand how it occurs. “Hemo” means blood, of course; “lysis” means to rupture or the destruction of cells. So hemolysis is literally the destruction of blood cells, specifically red blood cells.
