Uric Acid Crystals in Urine Analysis: Microscopy
Morphological features of uric acid crystals in urine sediment: macroscopic appearance, polymorphism of forms, and microscopic picture.
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.
