Quality Control Failure on a Biochemical Analyzer: A Case
A clinical laboratory quality control case: consistently low bilirubin on a biochemical photometer while other tests are normal. Determine the cause of the failure.
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.
