Macrocytes [Presence] in Blood by Light microscopy

Active

Part Description

LP17441-4   Macrocytes
Macrocytosis is the enlargement of red blood cells with near-constant hemoglobin concentration, and is defined by a mean corpuscular volume (MCV) of greater than 100 femtolitres (the precise criterion varies between laboratories).
Most commonly (especially when the increase in size is mild, and just above normal range) the etiology is bone marrow dysplasia primary to alcohol abuse and Chronic alcoholism. Other causes may include: Megaloblastosis (Vitamin B12 or folate deficiency; or DNA synthesis-inhibiting drugs), hypothyroidism, reticulocytosis (commonly from hemolysis or a recent history of blood loss), liver disease, myeloproliferative disease Copyright Text is available under the Creative Commons Attribution/Share-Alike License.

Change Reason

The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
