alteration, dissoultion, or destruction of red blood cells in such a manner that hemoglobin is liberated. The spleen normally filters the blood and removes abnormal red blood cells. If most cells are normal, the amount of hemoglobin released is easily metabolized by the liver and recycled by the body. If there are large numbers of abnormal red cells, the liver metabolizes the hemoglobin to bilirubin in quantities too great to be quickly recycled and jaundice results.[close window
The lysis or breakdown of erythrocytes by bacteria Caused by the secretion of bacterial hemolysins Detected by appearance of colonies on blood agar plates Types of hemolysis Beta hemolysis: Complete hemolysis; clear zone around colonies on blood agar Alpha hemolysis: Incomplete hemolysis; greenish zone around colonies on blood agar Gamma reaction: Absence of a hemolytic reaction; no change around colonies on blood agar
Destruction of red blood cells and release of hemoglobin.
The dissolution or dissolving of the erythrocytes.
(hee-MOHL-ih-sihs) The bursting of a red blood cell resulting from disruption of the plasma membrane by toxins, freezing or thawing, or exposure to a hypotonic solution.
Red blood cell destruction.
The destruction of the membrane of red blood cells.
destruction of red blood cells leading to release of hemoglobin.
Destruction of red blood cells. Malaria causes hemolysis when the parasites rupture the red blood cells in which they have grown.
The breaking or rupturing of blood cells. Staphylococci often causes hemolysis of the cells in blood agar.
breaking of the red blood cells.
The destruction of red blood cells which leads to the release of hemoglobin from within the red blood cells into the blood plasma . See the entire definition of Hemolysis
The lysis (destruction) of red blood cells.
When the red blood cells break apart. Hemolysis can cause interference for certain assays.
Rupture of red blood cells with release of hemoglobin (also spelt haemolysis)
the breakdown or destruction of red blood cells.
the breakdown of red blood cells in the spleen, which is normal but can cause jaundice and anemia when the red blood cells are broken down too quickly
Alteration, dissolution, or destruction of red blood cells in such a manner that hemoglobin is liberated into the medium in which the cells are suspended, e.g., by specific complement-fixing antibodies, toxins, various chemical agents, tonicity, alteration of temperature.
Generally speaking, this term refers to the disintegration of elements in the blood. A common form of hemolysis occurs during anemia and involves lysis or the dissolution of red blood cells.
The dissolution of red blood corpuscles with liberation of their hemoglobin, an iron-containing protein respiratory pigment occurring in the red blood cells.
Breaking a membranous covering or destroying red blood cells.
Red blood cell damage, which can lead to hemolytic anemia.
Hemolysis is the destruction of red blood cells with the release of hemoglobin into the surrounding fluid.
The breakdown (lysis) of red blood cells.
Destruction of red cells in the blood stream.
The rupture of red blood cells.
bursting (lysis) of red blood cells. One way of measuring vitamin E deficiency is by finding out how easily the red blood cells burst when subjected to lysing agents such as hydrogen peroxide. Higher serum levels of vitamin E protect the red blood cells against hemolysis, unless they are then exposed to even higher concentrations of the oxidant hydrogen peroxide.
Changes in red blood cells.
The rupturing of red blood cells which sometimes occurs during hemodialysis.
breaking down of red blood cells
A process characterized by the alternations in the red Blood cells' integrity resulting in the release of hemoglobin into the surrounding medium in which the cells are suspended. Hemolytic Disease of the Newborn (HDN) - Prior to 1940 the occurrence of severe neonatal jaundice, without known cause, in succeeding infants born to the same woman, was a relatively uncommon disease, though very well known, icterus gravis familiaris, now universally known as HDN. The most cause of HDN is maternal alloimmunization, possibly ABO incompatibility, but most cases documented cases of clinically severe HDN have been associated with Rh(D) incompatibility. HDN may occur when an Rh negative woman is carrying a fetus with an Rh positive genotype. A feto-maternal bleed resulting in fetal red cells entering the mother's circulation may cause Rh immunization. Rh HDN does not occur during the first pregnancy, but may occur in subsequent pregnancies.
Refers to the destruction of the red cell membrane. May be caused by several factors including the immune response, bacterial or viral infection and red cell membrane stress.
Normal breakdown or mechanical destruction of the red blood cell releasing hemoglobin.

Hemolysis (or haemolysis)—from the Latin Hemo-, Greek meaning blood, -lysis, meaning to break open— is the breaking open of red blood cells and the release of hemoglobin into the surrounding fluid (plasma, in vivo).
Hemolysis is used in the empirical identification of microorganisms based on the ability of bacterial colonies grown on agar plates to break down red blood cells in the culture. When the organism has been grown on blood agar plates, it can be classified with regard to whether or not it has caused hemolysis in the red blood cells (RBCs) incorporated in the medium. This is of particular importance in the classification of streptococcal species.
