Perfunnance evaluation on a latex enhanced immunoturbidimetricβ_2-microglobulin kit

Objective To evaluate the performance of a latex enhanced immunoturbidimetricβ2-microglobulin kit in clinical use. Methods The lower limit of detection,precision,accuracy and linearity range was determined on the automatic chemistry analyzer Hitachi 7170S. Results The lower limit of detection was 0. 09mg/L. The within-run precision was less than 4% while the between-run precision was less than 8%. The accuracy was 99.29 % and the linearity range was 0.2～18mg/L. Conclusion Theβ2-microgiobulin kit shows good performance in clinical use.
