Table 3 Comparison of the low-detection limit and the dynamic range of a CEA assay using commercially available kits (e.g. Siemens, Abbott, and Roche) and those for this work (denoted as this work)
Company/Model | Low-detection limit | Dynamic range | Approval |
|---|---|---|---|
Siemens/ADVIA Centuar CEA assay | 0.5 ng/ml | 0.5 - 100 ng/ml | USFDA |
Abbott/AXSYM system CEA assay | 0.5 ng/ml | 0.5 - 500 ng/ml | USFDA |
Roche/Elecsys CEA assay | 0.2 ng/ml | 0.2 - 1,000 ng/ml | USFDA, CE |
This work | 0.21 ng/ml | 0.21 - 500 ng/ml | None |
