Clinical tests for anemia include the hematocrit, which measures the amount of packed red blood cells per measured volume of blood; and the hemoglobin test, which measures the amount of the oxygen-carrying protein in the red blood cells.
Anemia can result from any one of a number of conditions: severe blood loss from an accident; low-grade, chronic internal bleeding; long-term marginal nutrient deficiencies, including poor dietary intake; impaired absorption of nutrients; or faulty use of the nutrient within the body, often due to long-term use of medication.
