The normal mean corpuscular volume (abbreviated to MCV on full blood count results, and also known as mean cell volume) is approximately 80–100 fL. When the MCV is <80 fL, the red cells are described as microcytic and when >100 fL, macrocytic (the latter occurs in macrocytic anemia). The MCV is the average red blood cell size.
Microcytosis. Specialty. Hematology. Microcytosis or microcythemia[1] is a condition in which red blood cells are unusually small as measured by their mean corpuscular volume. [2] When associated with anemia, it is known as microcytic anemia.
Blood loss, decreased red blood cell production, increased red blood cell breakdown [1] Diagnostic method. Blood hemoglobin measurement [1] Frequency. 1.92 billion / 24% (2021) [2] Anemia or anaemia (British English) is a blood disorder in which the blood has a reduced ability to carry oxygen.
This is a shortened version of the fourth chapter of the ICD-9: Diseases of the Blood and Blood-forming Organs. It covers ICD codes 280 to 289. The full chapter can be found on pages 167 to 175 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
The mean corpuscular volume is a part of a standard complete blood count. In patients with anemia, it is the MCV measurement that allows classification as either a microcytic anemia (MCV below normal range), normocytic anemia (MCV within normal range) or macrocytic anemia (MCV above normal range). Normocytic anemia is usually deemed so because ...
A myelodysplastic syndrome (MDS) is one of a group of cancers in which immature blood cells in the bone marrow do not mature, and as a result, do not develop into healthy blood cells. [3] Early on, no symptoms typically are seen. [3] Later, symptoms may include fatigue, shortness of breath, bleeding disorders, anemia, or frequent infections. [3]
The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3).
Autoimmune hemolytic anemia (AIHA) is an autoimmune disorder which occurs when antibodies directed against the person's own red blood cells (RBCs) cause them to burst (lyse), leading to an insufficient number of oxygen-carrying red blood cells in circulation (anemia). The lifetime of the RBCs is reduced from the normal 100–120 days to just a ...
