Clinical Case: Child's Urine Color Change
A clinical case on general urine analysis: a 12-year-old child with stomatitis has a urine sample with unusual coloration. Determine the possible cause of the change.
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.
