Important Note

CEA is elevated in the serum of patients with non-malignant diseases and in heavy smokers, therefore CEA should not be used for the diagnosis of cancer or for screening asymptomatic patients.

Intended Use

The Access CEA assay is a paramagnetic particle, chemiluminescent immunoassay for the quantitative determination of Carcinoembryonic Antigen (CEA) levels in human serum, using the Access Immunoassay Systems. CEA measured by the Access Immunoassay Systems is used as an aid in the management of cancer patients in whom changing CEA concentrations have been observed.
