[Comparison of three albumin assay methods: a need for standardization within a healthcare area].

Albumin is a main biomarker of denutrition severity. Since 2019, the French National Authority of Health (HAS) recommends an immunologic technique as a reference for measuring albuminemia. In a context of partial recovery by the laboratory of GHBS (using colorimetric method with bromcresol purple) of the biological activity of the dialysis center, until then carried out by the Ouest biology - Biolor laboratory (using colorimetric method with bromcresol green) and in order to standardize practices in the healthcare sector, we compared 3 albumin assay techniques: immunoturbidimetric (Diagam), BCG (Siemens), BCP (Siemens) on Siemens Atellica PLCs.
