Who anemia classification based on hemoglobin?

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 sex but also with ethnicity and physiological status.

What are the 3 classifications of anemia?

Anemia can be classified as microcytic, normocytic or macrocytic, depending on MCV.

What are the 4 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 anemia is classified based on morphology and hemoglobin concentration?

Anemia can be classified according to a deficient number of circulating red blood cells or a deficient hemoglobin concentration, or both. A classification of anemia on the basis rbc morphology, as seen in the peripheral blood smear and supported by the quantitative measurements of cell size (MCV) and-Hb.

What are the 7 types of anemia?

They include:
  • Iron deficiency anemia. This most common type of anemia is caused by a shortage of iron in your body. …
  • Vitamin deficiency anemia. …
  • Anemia of inflammation. …
  • Aplastic anemia. …
  • Anemias associated with bone marrow disease. …
  • Hemolytic anemias. …
  • Sickle cell anemia.

What is anemia and explain 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 is the difference between Macrocytic and microcytic anemia?

In microcytic anemia, red blood cells (RBCs) are smaller than normal. In macrocytic anemia, RBCs are larger than normal. Making this distinction in the size of RBCs will help doctors figure out the cause of a person’s anemia.

What is morphology classification of anemia?

Anemia is classified by morphology or pathophysiology. The morphological classification is based partly on the size or volume of the red blood cell. Normocytic would indicate a red blood cell of a normal size or volume. Microcytic indicates an abnormally small cell, and macrocytic indicates an abnormally large cell.

What are the morphological types of anemia?

There are three basic divisions within the morphologic classification system: Microcytic — MCV <80 fL. Macrocytic — MCV >100 fL. Normocytic — MCV 80-100 fL.

What are the 3 main causes of anemia?

Anemia has three main causes: blood loss, lack of red blood cell production, and high rates of red blood cell destruction.

What is classified severe anemia?

For all of the tested groups, moderate anemia corresponds to a level of 7.0-9.9 g/dl, while severe anemia corresponds to a level less than 7.0 g/dl.

How many types of anemia are there?

There are more than 400 types of anemia, and they’re 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 are the grades of anemia?

Grading of anemia, according to the National Cancer Institute, is as follows:
  • Mild: Hemoglobin 10.0 g/dL to lower limit of normal.
  • Moderate: Hemoglobin 8.0 to 10.0 g/dL.
  • Severe: Hemoglobin 6.5 to 7.9 g/dL[1]
  • Life-threatening: Hemoglobin less than 6.5 g/dL.

What is normal range of Hb?

The healthy range for hemoglobin is: For men, 13.2 to 16.6 grams per deciliter. For women, 11.6 to 15 grams per deciliter.

How do Microcytic and Macrocytic anemia differ?

In microcytic anemia, red blood cells (RBCs) are smaller than normal. In macrocytic anemia, RBCs are larger than normal. Making this distinction in the size of RBCs will help doctors figure out the cause of a person’s anemia.

What is the danger level of hemoglobin?

What hemoglobin levels are considered severe or dangerously low? A hemoglobin level of less than 5.0 grams per deciliter (g/dl) is dangerous and could lead to heart failure or death. A normal hemoglobin level is 13.2–16.6 grams per deciliter (g/dL) for males and 11.6–15 g/dL for females.

How is Haemoglobin measured?

Hemoglobin determinations will usually be performed by an automated cell counter from a tube of well-mixed EDTA-anticoagulated blood filled to a predetermined level. In this assay, all forms of hemoglobins are converted to the colored protein cyanomethemoglobin and measured by a colorimeter.

How is hemoglobin calculated?

The formula is hgb=MCV x RBC divided by 29.8.

What is test for hemoglobin called?

A hemoglobin electrophoresis (eh-lek-truh-fer-EE-sis) blood test measures the different types of hemoglobin. Normal hemoglobin carries and delivers oxygen well, but some abnormal types do not.

What is total hemoglobin?

The total hemoglobin (tHb) value in red blood cells (RBCs) is a critical measure of blood oxygen transport capacity. When the hemoglobin value abruptly declines due to hemorrhage, oxygenation of the tissue cannot be properly maintained.

What is Sahli’s method?

Sahil’s method is used to identify the quantity of hemoglobin present in the blood. Hemoglobin is the main constituent of blood that carries oxygen throughout our body. This method was first discovered by neurologist William Gowers. The Sahil’s hemoglobinometer consists of a tube, stirrer, pipette and comparator.

What is true haemoglobin?

The red blood cells contain a red pigment called haemoglobin. Haemoglobin binds to the oxygen and transports it to all parts of the body. Platelets help the blood to clot when there is a cut in the body.

What is MCV normal range?

Normal Results

These test results are in the normal range: MCV: 80 to 100 femtoliter. MCH: 27 to 31 picograms/cell. MCHC: 32 to 36 grams/deciliter (g/dL) or 320 to 360 grams per liter (g/L)
