What is anemia and its classification?
Anemia Defined and Classified. Anemia is defined as reduced oxygen carrying capacity of the blood. Functionally, anemia arises when there is insufficient hemoglobin or the hemoglobin is not functional. The physiologic function of hemoglobin is to deliver oxygen to the tissues.
What are the major classification of anemia?
Anemia can be classified as microcytic, normocytic or macrocytic, depending on MCV. As stated above, it can be hypo-regenerative or regenerative, which depends on the number of reticulocytes.
What is anemia in PDF?
Anemia occurs when the number of red blood cells or hemoglobin concentration is lower than normal. Low hemoglobin leads to a decrease in blood capacity to carry oxygen to the body’s different tissues. If anemia occurs, symptoms like fatigue, weakness, dizziness, and shortness of breath will appear.
What is classified as anemic?
Anemia is a medical condition in which the red blood cell count or the hemoglobin is less than normal. In men, anemia is typically defined as a hemoglobin level of less than 13.5 gram/100 ml and in women as hemoglobin of less than 12.0 gram/100 ml.
What are the classification of anemia based on the morphology of the red blood cells?
Anemia divided based on RBCs indices (MCV) into the following broad categories: Microcytic, MCV <80 fl. Normocytic, MCV 80 to 100 fl. Macrocytic, MCV >100 fl.
What are the 3 categories of anemia?
In general, the causes anemia can be divided into three groups: Anemia caused by blood loss. Anemia caused by decreased or faulty red blood cell production. Anemia caused by destruction of red blood cells.
What is Anaemia short answer?
Anemia (say: uh-NEE-mee-uh) happens when a person doesn’t have the normal amount of red blood cells or if the person is low on hemoglobin (say: HEE-muh-glow-bin). Hemoglobin, a protein, is an important part of red blood cells because it gives the oxygen something to stick to.
What is anemia short answer?
What are the main causes of anemia?
Common causes are blood loss, reduced or impaired RBC production, and the destruction of RBCs. The most common type is iron-deficiency anemia. It sometimes develops due to a diet lacking in nutrients, Crohn’s disease, or the use of certain medications. A doctor can use a CBC blood test to help detect anemia.
What is Anaemia Slideshare?
anemia is define as decrease in Hb concentration below the lower limit of normal value according to the age and sex of the individual is call anemia. anemia can be classify by different ways some are as in this presentation. Asif Zeb. Lecturer at Shaukat Khanum Memorial Cancer Hospital and Research Centre.
Which classification would describe the anemia caused by acute blood loss?
Normocytic anemias (MCV 80-100 fL) include anemias of acute blood loss, hemolysis, uremia, and cancer.
How is anemia defined by the World Health Organization?
According to the World Health Organization (WHO), anemia is defined as hemoglobin (Hb) levels <12.0 g/dL in women and <13.0 g/dL in men. However, normal Hb distribution varies not only with … Anemia is a global public health problem affecting both developing and developed countries at all ages.
What are the names of the different types of anemia?
Many types of anemia exist, such as iron-deficiency anemia, pernicious anemia, aplastic anemia, and hemo-lytic anemia. The different types of anemia are linked to various diseases and conditions.
How are red cell indices used to classify anemia?
Anemia is a state of decreased red cell mass of blood leading to decreased oxygen carrying capacity of body. Red cell indices are useful in classifying anemia. Anemias are classified etiologically and morphologically. In this chapter we will discuss about red cell indices and also about classification of anemia.
What happens to the red blood cells in anemia?
Anemia is defined as the state in which the red cell mass of blood is decreased below the normal level for the age and sex of the patient. As a result of this the oxygen carrying capacity of blood is decreased. It is characterized by a decrease in hemoglobin, packed red cell volume (PCV) and red blood cell (RBC) count.
