System information

For cobas e 411 analyzer: test number 360

For cobas e 601 and cobas e 602 analyzers: Application Code Number 055

Please note

The measured CA 72‑4 value of a patient’s sample can vary depending on the testing procedure used. The laboratory finding must therefore always contain a statement on the CA 72‑4 assay method used. CA 72‑4 values determined on patient samples by different testing procedures cannot be directly compared with one another and could be the cause of erroneous medical interpretations. If there is a change in the CA 72‑4 assay procedure used while monitoring therapy, then the CA 72‑4 values obtained upon changing over to the new procedure must be confirmed by parallel measurements with both methods.

Intended use

Immunoassay for the in vitro quantitative determination of CA 72‑4 in human serum and plasma. The assay in particular serves as an aid in the therapeutic monitoring of carcinomas of the stomach and ovaries. The electrochemiluminescence immunoassay “ECLIA” is intended for use on Elecsys and cobas e immunoassay analyzers.
