1. Introduction - Why Tumor Marker Screening Matters
Cancer remains a major global health challenge. While tissue biopsy and imaging are gold standards, serum tumor marker testing provides a minimally invasive way to support early detection, disease monitoring, and recurrence surveillance, especially when combined in optimized diagnostic panels.
Among these markers, Carcinoembryonic Antigen (CEA) has been widely studied and used in clinical practice, especially for gastrointestinal malignancies.
2. CEA and Multi-Tumor Marker Diagnostics
What is CEA?
● Carcinoembryonic antigen (CEA) Test Kit is designed for the quantitative detection of CEA, a glycoprotein that is commonly elevated in gastrointestinal malignancies.
● Most clinically relevant in colorectal, gastric, and pancreatic cancers.
● Useful for early detection in high-risk populations and monitoring recurrence after treatment.
Combining CEA Testing with Other Relevant Markers
● Single CEA measurement may miss early-stage tumors.
● Multi-marker panels improve sensitivity and specificity by complementing CEA with other tumor-specific markers.


Key Takeaways:
Multi-marker panels improve early cancer detection beyond CEA alone.
Suitable for high-risk screening and post-treatment monitoring.
