Sickle cell disease (SCD), also simply called sickle cell, is a group of hemoglobin-related blood disorders that are typically inherited. [2] The most common type is known as sickle cell anemia. [2] Sickle cell anemia results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [2]
The underlying cause of sickle cell anemia is the synthesis of aberrant hemoglobin, which attaches to other aberrant hemoglobin molecules inside the red blood cell to undergo rigid deformation. [18] Sickle cell anemia symptoms usually appear around the age of six months. They can change over time and differ from person to person.

However, people with co-morbidities such as anemia, cardiovascular disease, lung disease, sepsis, or who have abnormal hemoglobin species (e.g. carboxyhemoglobin, sulfhemoglobinemia or sickle hemoglobin) may experience moderate to severe symptoms at much lower levels (as low as 5–8%).
Iron-deficiency anemia: D50: 6947: Iron-deficiency anemia (or iron deficiency anaemia) is a common anemia that occurs when iron loss (often from intestinal bleeding or menses) occurs, and/or the dietary intake or absorption of iron is insufficient. In such a state, hemoglobin, which contains iron, cannot be formed. [5]
The test uses the principles of gel electrophoresis to separate out the various types of hemoglobin and is a type of native gel electrophoresis.After the sample has been treated to release the hemoglobin from the red cells, it is introduced into a porous gel (usually made of agarose or cellulose acetate) and subjected to an electrical field, most commonly in an alkaline medium.
The mean corpuscular hemoglobin concentration (MCHC) is a measure of the concentration of hemoglobin in a given volume of packed red blood cell. It is calculated by dividing the hemoglobin by the hematocrit. Reference ranges for blood tests are 32 to 36 g/dL (320 to 360g/L), [1] or between 4.81 and 5.58 mmol/L.
Normocytic anemia is a type of anemia and is a common issue that occurs for people typically over 85 years old. Its prevalence increases with age, reaching 44 percent in men older than 85 years. [1] The most common type of normocytic anemia is anemia of chronic disease. [1]
