Red blood cells are normally in a biconcave shape (round cells in this picture). Schistocytes are fragmented cells resulting from intravascular destruction with shapes that differ from the normal round red blood cells. Serum tests evaluate plasma bilirubin, haemolysis and liver function and are essential for
When red blood cells complete their lifespan of about 120 days, or if they are damaged, they rupture as they pass through the reticuloendothelial system, and cell contents including hemoglobin are released into circulation. Macrophages phagocytose free hemoglobin and split it into heme and globin. Two reactions then take place with the heme ...
Bilirubin (BR) (from the Latin for "red bile") is a red-orange compound that occurs in the normal catabolic pathway that breaks down heme in vertebrates.This catabolism is a necessary process in the body's clearance of waste products that arise from the destruction of aged or abnormal red blood cells.

Blood smear of a patient with Thrombotic Thrombocytopenic Purpura (TTP). Notice that some red blood cells are nucleated. This is a characteristic finding in such blood smears. Autoimmune hemolytic anemia (AIHA), in which autoantibodies react with self red blood cells and cause their destruction. [5]
Urobilinogen is a yellow by-product of bilirubin reduction. It is formed in the intestines by the bacterial enzyme bilirubin reductase. [1] About half of the urobilinogen formed is reabsorbed and taken up via the portal vein to the liver, enters circulation and is excreted by the kidney.
It also plays a central role in building energy and proteins, and it can be found in your red blood cells, bone marrow, muscles and the brain. You may hear the terms " iron deficient " and "iron ...
Bile (yellow material) in a liver biopsy stained with hematoxylin-eosin in a condition called cholestasis (setting of bile stasi). Bile (from Latin bilis), or gall, is a yellow-green/misty green fluid produced by the liver of most vertebrates that aids the digestion of lipids in the small intestine.
Red blood cells from somewhere else An intriguing question raised by the study is how the folate-deprived mice still managed to have enough red blood cells to avoid developing anemia. “That’s ...
