Tumor Markers

Point-of-care rapid testing for tumor markers. OEM/ODM manufacturer.

Overview

Tumor markers are proteins associated with certain cancers, used in screening support and monitoring of high-risk groups.

Tumor markers are proteins associated with certain cancers, used in screening support and monitoring, not standalone diagnosis.

PSA (prostate) · AFP (hepatocellular) · CEA (colorectal) · CA-series.

Tumor-marker tests detect proteins (antigens); some autoimmune serology (RF) uses antibody detection.

Elevated marker (PSA/AFP/CEA) → imaging + biopsy → confirmed diagnosis → serial monitoring.

Not time-critical; used in screening support and serial monitoring.

Elevated tumor markers are not diagnostic of cancer — imaging and confirmatory testing are required; markers also rise in benign conditions.

False negative: non-secreting tumors. False positive: markers also rise in benign conditions.

Imaging and biopsy; markers are not diagnostic alone.

Screening support and monitoring in clinics and labs; imaging/biopsy are definitive.

NCCN guidelines; national cancer-screening recommendations.

Position: Sell tumor markers as monitoring aids, never as standalone cancer tests — the honest framing is the only sustainable one.

PSA/AFP/CEA rise in benign conditions too; imaging and confirmatory testing are required.
Overclaiming a cancer-screening use creates regulatory and reputational risk.
High-risk surveillance and monitoring are the legitimate, defensible use cases.

This is the buyer-advisor view of the technical team — editorial guidance, not a substitute for product IFU or local regulatory requirements.

No — PSA, AFP and CEA rise in benign conditions too, and confirmation requires imaging and other testing. They are monitoring/screening-support aids.

Prostate cancer screening support and monitoring; elevated PSA prompts further evaluation (biopsy), but is not cancer-specific.

Hepatocellular carcinoma (liver cancer) — used in high-risk surveillance and monitoring, alongside imaging.
