Representative performance data on the analyzers are given below. Results obtained in individual laboratories may differ.
Precision was determined using human samples and controls in an internal protocol with repeatability (n = 21) and intermediate precision (3 aliquots per run, 1 run per day, 21 days). The following results were obtained:
Lithium values for human serum samples obtained with the lithium reagent on a Roche/Hitachi cobas c 501 analyzer (y) were compared to those determined with the same reagent on a Roche/Hitachi 917 analyzer (x) and with the lithium ion-selective electrode on a COBAS INTEGRA 400 analyzer (x).
