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 ...
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.
Macrocytosis is a condition where red blood cells are larger than normal. [1] These enlarged cells, also known as macrocytes, are defined by a mean corpuscular volume (MCV) that exceeds the upper reference range established by the laboratory and hematology analyzer (usually >110 fL). [2]
Molar concentration (mol/L) is used to a higher degree in most of the rest of the world, including the United Kingdom and other parts of Europe and Australia and New Zealand. [ 4 ] International units (IU) are based on measured biological activity or effect, or for some substances, a specified equivalent mass.
Folate and vitamin B 12 deficiency anemia usually presents with high RDW and high MCV. Mixed-deficiency (iron + B 12 or folate) anemia usually presents with high RDW and variable MCV. Recent hemorrhages typically present with high RDW and normal MCV. A false high RDW reading can occur if EDTA anticoagulated blood is used instead of citrated blood.
A high reticulocyte count signifies that bone marrow processes are normal. A low reticulocyte count would signify there is a problem at the level of the bone marrow, which produce the stem cells . Acute blood loss would result in a high reticulocyte count, as bone marrow processes are normal and the bone marrow responds accordingly to the body ...
In thalassemia major, mean corpuscular volume (MCV) are less than 70 fl, in thalassemia intermedia, MCV levels are below 80 fl (The normal range for MCV is 80–100 fl). [66] The Mentzer index can be a pointer for diagnosis of thalassemia; it can can be calculated from a CBC report.
The relationship between the amount of vitamin B 6 consumed and the serum levels of those who consume it varies between individuals. [52] Some people may have high serum concentrations without neuropathy symptoms. [13] [53] [54] It is not known if inhalation of vitamin B 6 while, for example, working with animal feed containing vitamin B 6 is ...
