Intrinsic factor Intrinsic factor. Intrinsic factor (IF), also known as gastric intrinsic factor (GIF), is a glycoprotein produced by the parietal cells of the stomach. It is necessary for the absorption of vitamin B12 (cobalamin) later on in the small intestine. In humans, the gastric intrinsic factor protein is encoded by the GIF gene.

- The defect may be in the red blood cell itself (intrinsic factor), or outside the red blood cell (extrinsic factor). Causes of hemolytic anemia include infection, certain medications, autoimmune disorders (such as Lupus), and inherited disorders. There are several different types of anemia. There is no known prevention for hemolytic anemia. These are tests for hemolysis (red blood cell destruction).

Pernicious Anemia (Vitamin B-12 Deficiency) Pernicious anemia is a type of anemia (reduced number of red blood cells or hemoglobin in the body) due to the body's inability to absorb vitamin B-12 from the gastrointestinal tract. Symptoms from anemia are a result of the decreased capacity of the blood to carry oxygen and include fatigue and shortness of breath.In addition, the deficiency of vitamin B-12 also can damage the nervous system. Vitamin B-12 is also known as cobalamin (Cbl).ernicious anemia is a form of megaloblastic anemia. Megaloblastic anemia is characterized by an abnormally large size of red blood cell (megaloblast) that is formed by the bone marrow when vitamin B-12 or folic acid levels are low.

INTRODUCTION Megaloblastic Anemia (MGA), also known as Pernicious Anemia, is a rare blood disorder characterized by the presence of large, structurally and visually abnormal, immature red blood cells (megaloblasts). Decreased numbers and immaturity of white blood cells (leukocytes) and blood platelets (thrombocytes) may also occur.

Intrinsic factor Some people do not make enough intrinsic factor or have a condition that destroys it. If your body does not make enough intrinsic factor, you can develop a type of vitamin B12 deficiency called pernicious anemia.

Useful For Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test. Vitamin B12 deficiency can be caused by many factors, one of which is pernicious anemia, a condition resulting in deficient production of intrinsic factor in the parietal cells of the stomach. Intrinsic factor is a protein that is needed to assist in the absorption of vitamin B12 into the small intestine.

Anatomy/Digestive Secretion List Intrinsic factor is an enzyme (glycoprotein) secreted by the parietal cells of the stomach. It assists in the absorption of vitamin B12 by protecting the acid-intolerant substance as it goes through the stomach.

Parietal cell Parietal cells also produce intrinsic factor. Intrinsic factor is required for the absorption of Vitamin B12 in the diet. A long-term deficiency in vitamin B 12 can lead to megaloblastic anemia, characterized by large fragile erythrocytes.arietal cells (also known as oxyntic or delomorphous cells), are the epithelial cells that secrete hydrochloric acid (HCl) and intrinsic factor. These cells are located in the gastric glands found in the lining of the fundus and in the body of the stomach.

Anemia Anemia is the most common disorder of the blood with it affecting about a quarter of people globally. Iron-deficiency anemia affects nearly 1 billion. In 2013 anemia due to iron deficiency resulted in about 183,000 deaths – down from 213,000 deaths in 1990. Pernicious anemia is caused by a lack of intrinsic factor, which is required to absorb vitamin B 12 from food. 2  A lack of intrinsic factor may arise from an autoimmune condition targeting the parietal cells (atrophic gastritis) that produce intrinsic factor or against intrinsic factor itself.

Intrinsic factor In human beings it is present in the fundus and body of the stomach. The limited amount of normal human gastric intrinsic factor limits normal efficient absorption of B12 to about 2 mcg per meal, a nominally adequate intake of B12.he intrinsic factor is secreted by the stomach. It is present in the gastric juice as well as in the gastric mucous membrane. The optimum pH for its action is 7 and it is inactivated at temperatures above 45 °C.

Parietal Cell Antibody How is it used? An intrinsic factor antibody (IF antibody) test may be used to help determine the cause of a vitamin B12 deficiency and to confirm a diagnosis of pernicious anemia. Pernicious anemia is caused by vitamin B12 deficiency due to a lack of intrinsic factor. This condition occurs primarily when the body's immune system targets its own tissues and develops antibodies directed against the parietal cells and/or the intrinsic factor.

What does intrinsic medical renal disease mean? Responses (1) Intrinsic renal disease is a type of kidney disease that is often the result of an injury to the kidneys. Intrinsic or intrarenal acute renal failure (ARF) occurs when direct damage to the kidneys causes a sudden loss in kidney function. The disease also is caused by lack of blood to the kidneys, drug abuse and inflammation from other causes.

Vitamin B12 deficiency anemia Pernicious anemia due to lack of intrinsic factor is not preventable. Vitamin B12 deficiency due to other causes may be prevented with a balanced diet or with supplements. Pernicious anemia can be easily treated with either injections or pills of vitamin B12.

Anemia, Megaloblastic Megaloblastic anemia is a condition in which the bone marrow produces unusually large, structurally abnormal, immature red blood cells (megaloblasts). Bone marrow, the soft spongy material found inside certain bones, produces the main blood cells of the body-red cells, white cells, and platelets.Anemia is a condition characterized by the low levels of circulating, red blood cells.ernicious anemia is a rare blood disorder characterized by the inability of the body to properly utilize vitamin B12, which is essential for the development of red blood cells. Most cases result from the lack of the gastric protein known as intrinsic factor, without which vitamin B12 cannot be absorbed.

This page Pernicious Anemia. Pernicious anemia (PA) is an autoimmune disorder in which the body fails to make enough healthy red blood cells (RBCs). The body requires vitamin B-12 and a type of protein called intrinsic factor (IF) to make red blood cells. Vitamin B-12, or cobalamin, is found in certain foods and medications.

Factor II Deficiency Factor II deficiency is a very rare blood clotting disorder that results in excessive or prolonged bleeding after an injury or surgery. Factor II, also known as prothrombin, is a protein made in your liver that plays an essential role in blood clotting.ymptoms may vary from mild to severe. In very mild cases, blood clotting may just be slower than normal. In cases of severe factor II deficiency, symptoms may include: 1  umbilical cord bleeding at birth. 2  unexplained bruising. 3  abnormal bleeding after giving birth, having surgery, or being injured. 4  nose bleeds.
