| Biomarker | CEA | Full name | Carcinoembryonic antigen | Molecular Type | Protein |
|---|---|---|---|---|---|
| Molecular Formula | / | Molecular Weight | / | Core Functional Dimensions | Prognosis |
| Disease | Cervical Cancer | Disease Subtypes | / | ||
| Organ | Cervix | Test Sample / Technology Platform | Serum (ELISA, CLIA, immunoturbidimetry) | ||
| Pathobiological Mechanisms | The antigens expressed during the embryonic stage, which are abnormally activated and expressed in cervical cancer, are related to tumor invasion and metastasis. | ||||
| Clinical Availability Status | Clinical routine auxiliary use: Only for comprehensive assessment, not used as a standalone diagnostic basis. | ||||
| Notes and Dynamics | The specificity is relatively low (about 60%), and false positives are more likely to occur in digestive tract tumors and inflammatory diseases. Persistent elevation of CEA indicates an increased risk of recurrence. | ||||
