Doctor's Assessment Included
Every result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
CEA (Carcinoembryonic Antigen)
CEA is a broad tumor marker that, when included in a comprehensive health panel, contributes to a thorough baseline profile for performance-focused individuals.
What It Measures
CEA measures the blood concentration of carcinoembryonic antigen, a glycoprotein involved in cell adhesion during early foetal development. In healthy adults, CEA is present at very low levels. Elevated concentrations may reflect increased cellular activity in various tissues.
Why It Matters
CEA is widely used to monitor certain conditions over time and assess treatment response. Because CEA can be elevated by many benign factors — most notably smoking — a single raised result should always be reviewed in full clinical context.
When to Test
CEA testing is typically recommended by a healthcare provider rather than self-requested. Consult your healthcare provider before arranging this test independently.

Lifestyle Tips
Not smoking is the single most impactful lifestyle change for reducing CEA levels. A diet rich in vegetables, fruit, and whole grains — combined with regular physical activity and limited alcohol — supports overall colon health.
