A novel sol particle immunoassay for fecal calprotectin in inflammatory bowel disease patients.

Background: We introduce a new assay method to measure the concentration of fecal calprotectin that can be applied in exclusive analyzers. The assay method uses gold colloidal reagents. In addition, we report performance evaluation results for the new method and the results of comparisons with enzyme-linked immunosorbent assay (ELISA) methods.

Evaluation of haemoglobin A1c measurement by an enzymatic method using an automated analyser that has an on-board haemolysis system.

Background: Enzymatic assays, which can be run on a general automated clinical analyser, have been developed for haemoglobin A1c (HbA1c) measurement. The performance of the BM Test HbA1c which is an enzymatic HbA1c assay was evaluated using the Bio Majesty (BM)6010/C, which has an on-board haemolysis system.

Methods: We evaluated whether the difference in sampling position from the centrifuged erythrocyte layer caused a difference in HbA1c values obtained by the BM6010/C and the Tosoh G7.
