Hypochromic anemia is the commonest type of anemia encountered in family practice. Although iron deficiency is by far the most common cause, it cannot be readily distinguished from hypochromic anemia due to other causes (thalassemia, secondary anemia and sideroblastic anemia) without knowing the state of the tissue iron stores. Treatment with iron should not be commenced until this is known. To establish the reason for the hypochromic state, the following tests are suggested: serum ferritin, bone marrow assessment of iron stores, plus serum iron and iron binding capacity.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
On the other...
Hypoxia
Types of Hypoxia
There are four primary types of hypoxia, each resulting from a different cause:
1. Anemic hypoxia: This type occurs due to insufficient oxygen delivery caused by a lack of red blood cells (RBCs) or RBCs with abnormal or...

Erythropoiesis
Factors Affecting Erythropoiesis
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.
EPO then...
Hemoglobin
When all four heme groups are bound to oxygen, the resulting molecule is called oxyhemoglobin. As a result, arterial blood...
