Ferritin assay performed on the Technicon Immuno 1 analyser using serum and plasma samples
Ferritin assays were performed using both serum and plasma samples on the Bayer Technicon Immuno 1 Analyser and their ferritin test kit as only data for serum samples are available. After evaluation of the test kit and analyser the results were correlated using the Statistica for Windows programme. It was established that the plasma samples gave consistently lower values than the serum samples. Using the obtained conversion factor of 1.191, plasma as well as serum samples may be used for ferritin determinations.
