摘要: Abstract Background Soluble transferrin receptor (sTfR) assays are currently not standardized. This hinders data comparison between studies and also affects the use of a recently proposed model to estimate body iron. Methods We evaluated analytical performance fully automated sTfR immunoturbidimetric assay (Roche Diagnostics) compared it with two ELISA (Ramco Laboratories an in-house used in iron model). Results The Roche showed excellent intra- inter-assay precision (CV 0.8); however, values by were on average 30% lower than obtained assays. Conclusions measured can be commonly assay, through regression equations present study.
