Precision and Accuracy in Laboratory Quality Control
Definitions of precision and accuracy in clinical diagnostic laboratories according to GOST R 53133.2-2008: impact of random errors and deviation assessment.
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.
