WebHow is beta thalassemia defined? MCV normal range = 80-100 fL. This patient has normal RBC size or is normocytic.

The thalassemias are a group of hemoglobinopathies in which the normal ratio of alpha globin to beta globin production is disrupted due to a genetic variant in one or more alpha or beta globin genes. This abnormal alpha chain to beta chain ratio causes the unpaired chains to precipitate, leading to destruction of red … portable tv with built in dvd
