Catalog Number: 03737551160
Immunoassay for the in vitro quantitative determination of ferritin in human serum and plasma.
Store at 2-8 °C.
Traceability: The Ferritin assay ( 03737551) has been standardized against the Ferritin assay ( 11820982). The Ferritin assay ( 11820982) has been standardized against the Enzymun-Test Ferritin method. This in turn has been standardized against the 1st International Standard (IS) NIBSC (National Institute for Biological Standards and Control) “Reagent for Ferritin (human liver)” 80/602. Recovery studies, including a published study9, to assess traceability of the Elecsys Ferritin assay to more recent international standards (2nd IS 80/578 and 3rd IS 94/572) have been conducted, with results showing very good agreement.
0.500-2000 µg/L (ng/mL) (defined by the lower detection limit and the maximum of the master curve). Values below the lower detection limit are reported as < 0.500 µg/L (ng/mL). Values above the measuring range are reported as > 2000 µg/L (ng/mL) (or up to 100000 µg/L (ng/mL) for 50-fold diluted samples).

Representative performance data on the analyzers are given below. Results obtained in individual laboratories may differ.
Precision was determined using Elecsys reagents, pooled human sera, and controls in a protocol(EP5-A2) of the CLSI (Clinical and Laboratory Standards Institute): 2 runs per day in duplication each for 21 days (n = 84). The following results were obtained:
A comparison of the Ferritin assay, 03737551 (y) with the Ferritin assay, 11820982 (x) using clinical samples gave the following correlations:
