To the Editor: Because the mean corpuscular
volume (MCV) of red blood cells may be elevated in as many as 89% of patients
with chronic alcohol use1 this test is often
used as a marker of ongoing alcohol abuse.2
It is not known, however, whether the MCV returns to normal after cessation
of chronic alcohol use.
