Evaluation of the IFCC-based reagent kit LUMIPULSE Presto TSH IFCC

Abstract

We evaluated the IFCC-based reagent kit LUMIPULSE Presto TSH IFCC. The within-run and between-day precisions were 0.7–1.2%, and 1.0–1.1%, respectively. The diluted linearity and lower limit of detection were 176.20 and 0.006 μIU/mL, respectively. There were no significant differences in results between autodilution and manual dilution. The correlation coefficient (r) between LUMIPULSE Presto TSH IFCC and LUMIPULSE Presto TSH was 0.999. The stability of serum in storage was high in LUMIPULSE Presto TSH IFCC. A good correlation was obtained in the comparison between serum and heparin plasma levels. The basal performance of the LUMIPULSE Presto TSH IFCC is satisfactory and it can be used for measurements with high sensitivity.
