Gut Health Blood Test
Mar 13, 2026
Gut Health Blood Test
A gut health blood test measures key markers related to digestive function, intestinal inflammation, nutrient absorption, and conditions like coeliac disease and inflammatory bowel disease—because many digestive problems leave measurable traces in your blood. While not replacing stool tests for complete gut assessment, blood tests identify nutrient deficiencies, rule out serious conditions, and guide further investigation.
At Blood Test London, gut health blood testing costs from £295 with results in 2-3 days. A doctor always reviews every result.
