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 a modified NCCLS EP5‑T2 protocol (repeatability n = 63, intermediate precision n = 63). The following results were obtained on a Roche/Hitachi cobas c 501 analyzer.
The following compounds were tested for cross‑reactivity.
