[Evaluation of the effect of hemolysis, bilirubin, lipemy, glucosis and natrium on mean concentration of hemoglobin (XN 2000 Sysmex)].

We evaluated the effect of haemolysis, bilirubin, lipemia, hyperglycemia and natremia on mean corpuscular haemoglobin concentration (MCHC) measured by XN 2000 (Sysmex). Our evaluation had shown than correction is necessary for haemolysis and lipemia but not for icterus. There were not possible to reproduce variation of MCHC with hyperglycemia or variation of natremia.
