A hemoglobin test measures the amount of hemoglobin in your blood. If a hemoglobin tests shows that a person's levels are below normal, it means they have a low red blood cell count, which is known as anemia. If the test shows higher levels than normal, it means they have hemoglobinemia. [citation needed] The normal range for hemoglobin is:
There are two types of Alpha-thalassemia, named hemoglobin Bart hydrops fetalis syndrome (also known as Hb Bart syndrome) and HbH disease. [22] Anemia: D50-D64: 663: Anemia is a type of medical condition that results in a decrease in the number of red blood cells (RBCs) or less than the normal quantity of hemoglobin in the blood. [2] Anemia of ...
Main symptoms that may appear in anemia [20] The hand of a person with severe anemia (on the left, with ring) compared to one without (on the right). A person with anemia may not have any symptoms, depending on the underlying cause, and no symptoms may be noticed, as the anemia is initially mild, and then the symptoms become worse as the anemia worsens.
Iron-deficiency anemia is anemia caused by a lack of iron. [3] Anemia is defined as a decrease in the number of red blood cells or the amount of hemoglobin in the blood. [3] When onset is slow, symptoms are often vague such as feeling tired, weak, short of breath, or having decreased ability to exercise. [1]
Hemoglobin in the blood carries oxygen from the lungs to the other tissues of the body, where it releases the oxygen to enable aerobic respiration which powers the metabolism. Normal levels of hemoglobin vary according to sex and age in the range 9.5 to 17.2 grams of hemoglobin in every deciliter of blood. [6] Hemoglobin also transports other ...
A complete blood count (CBC), also known as a full blood count (FBC), is a set of medical laboratory tests that provide information about the cells in a person's blood.The CBC indicates the counts of white blood cells, red blood cells and platelets, the concentration of hemoglobin, and the hematocrit (the volume percentage of red blood cells).
The World Health Organization defines low ferritin in adults as below 15 nanograms per milliliter, but in clinical practice, iron deficiency may be diagnosed when ferritin is below 30 nanograms ...
Polycythemia is defined as serum hematocrit (Hct) or hemoglobin (HgB) exceeding normal ranges expected for age and sex, typically Hct >49% in healthy adult men and >48% in women, or HgB >16.5 g/dL in men or >16.0 g/dL in women. [8] The definition is different for neonates and varies by age in children. [9] [10]
