Basophilic Stippling of Erythrocytes in a Blood Smear
Morphological features of erythrocytes in hemolytic anemia: detection of basophilic stippling in a peripheral blood smear.
Articles
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.
