Parameter
| Biomarker | Procalcitonin (PCT) | Full name | Procalcitonin | Molecular Type | Protein |
|---|---|---|---|---|---|
| Molecular Formula | Molecular Weight | ~13 kDa | Core Functional Dimensions | Differential diagnosis (infection vs tumor) | |
| Disease | Cholangiocarcinoma (CCA) | Disease Subtypes | / | ||
| Organ | Bile duct/Liver | Test Sample / Technology Platform | Serum (immunoassay, POCT) | ||
| Pathobiological Mechanisms | Advanced cholangiocarcinoma can be abnormally elevated, which is related to tumor progression; septic shock-like elevation may also occur in the absence of bacterial infection | ||||
| Clinical Availability Status | Clinically available (infection identification); It should be combined with the clinical scenario | ||||
| Notes and Dynamics | Patients with advanced cholangiocarcinoma may have a high level of >100ng/mL, and bacterial infection should be excluded to avoid misjudgment | ||||
