Mechanisms of MCV Changes: Microcytosis and Macrocytosis
Diagram of mean corpuscular volume (MCV) changes. Pathogenesis of microcytosis and macrocytosis in iron deficiency, vitamin B12 deficiency, folate deficiency, and liver pathologies.
Blood and bone marrow morphology, clinical cases and diagnostic algorithms. Most of the library is in Russian; the English section is growing.
Most of our material is written in Russian — that is the working language of the community. A few pieces exist in English; the rest of the library is one click away and the photographs need no translation.
