Gut Microbiome Screening

Type

Blood Testing

Duration

30 min

Results

5 days

Next Generation Sequencing (NGS) detection of over 100 gut microbiota species via stool testing. Analyzes relationship to obesity, IBS, diabetes, high cholesterol, cardiovascular disease, colon polyps, depression, rheumatoid arthritis, and macular degeneration. Includes physician assessment, personalized dietary recommendations, and lifestyle guidance.

Digestive and gut health blood tests evaluate markers related to gastrointestinal function, inflammation, and infection. These may include calprotectin (a stool marker for intestinal inflammation that helps distinguish IBS from IBD), H. pylori testing (the bacterium that causes stomach ulcers and is linked to gastric cancer), bile acid levels, and various antibody tests. Gut health is increasingly recognized as central to overall wellness, with the gut microbiome influencing immune function, mental health, nutrient absorption, and systemic inflammation. Testing can help identify treatable conditions causing chronic digestive symptoms.
