Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Comparison of interpretation of acute lymphoblastic leukemia (ALL) flow cytometric diagnostics data was the aim of the study. Immunophenotyping data obtained from 10 patients with ALL were analysed separately in 26 laboratories from Russian Federation and Kazahstan. Results comparison showed four main type of discordance: B-lineage ALL diagnostics during heavy bone marrow regeneration, great variability of T-ALL interpretation, complexity of ambiguous lineage acute leukemia and, finally, very different report types, unique for each laboratory. All these problems are the serious obstacles for standardization of flow cytometric ALL diagnostics in multicenter setting. Continuation of similar QC rounds following by consecutive discussions with further development of consensus diagnostic algorithm could be the first step for standardization of ALL immunophenotyping in Russian Federation and CIS countries.
