Understanding Lab Tests for Colon Cancer
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Colon cancer is typically diagnosed through methods such as colonoscopy and tissue biopsy. There is no single blood test that can definitively diagnose colon cancer itself; however, blood testing plays an important supportive role in assessing nutritional factors, monitoring overall health, and evaluating elements that may influence cancer risk.
Recommended Test
Folate, RBC
This test measures folate levels in red blood cells, providing insight into long-term folate status. Research suggests there may be a complex relationship between folate levels and colon cancer risk, with some studies indicating that very high folate levels could potentially increase risk. Monitoring folate status helps assess this important nutritional factor, though more research is needed to fully understand this association.
