Why hematocrit level is increased in pernicious anemia?
The hematocrit can be increased, but is not always increased in PA. The peripheral blood usually shows a macrocytic anemia with a mild leukopenia and thrombocytopenia. The mean cell volume (MCV) and mean cell hemoglobin (MCH) are increased, with a mean corpuscular hemoglobin concentration (MCHC) within the reference range.
