METHODS: Among the 578 professionals, 169 (29%) answered to the 10 questions dealing with the identification and measurements of schistocytes as proposed by the ICSH.
RESULTS: A consensus was reached for the urgent need of such guidelines documents, especially in the current background of the European accreditation EN ISO 15189 rules. A traduction in native (French) language was warmly wished in order to facilitate the diffusion of the information. The pathologic threshold for the diagnosis of thrombotic microangiopathic anemia (TMA) (>1%) remained questionable. For half of the biologists, the new fragmented red blood cell (FRC) parameter recently provided by two manufacturers of automated blood cell counters was still doubtful for routine use.
CONCLUSIONS: This survey assessed the impact of international \'guidelines\' on the French biological community. The will to implement validated recommendations was strong, reflecting the awareness of the biologists to standardize the laboratory investigations.
