Macroamylasemia Definition. Macroamylasemia is the presence of an abnormal substance called macroamylase in the blood. Causes. Macroamylase is a substance that consists of an enzyme, called amylase, attached to a protein. Because it is large, macroamylase is filtered very slowly from the blood by the kidneys.
Background. Macrocytosis is a term used to describe erythrocytes that are larger than normal, typically reported as mean cell volume (MCV) greater than 100 fL. The amount of hemoglobin increases proportionately with the increase in cell size.itamin B-12 deficiency is a cause of macrocytosis. Because DNA synthesis requires cyanocobalamin (vitamin B-12) as a cofactor, a deficiency of the vitamin leads to decreased DNA synthesis in the erythrocyte, thus resulting in macrocytosis.
