Comprehensive microbiome test analyzing beneficial and pathogenic bacteria, parasites, and yeast.
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.
Key Details
Who Is This For?
Anyone with chronic digestive symptoms like bloating, pain, diarrhea, or constipation. People suspected of having inflammatory bowel disease (Crohn's or ulcerative colitis). Those with a history of stomach ulcers or H. pylori infection. Anyone interested in optimizing their gut health as part of a broader wellness strategy.
What's Included
Preparation Required
Preparation varies by specific test. Blood-based tests generally don't require fasting. Stool-based tests require a sample collection kit provided by the lab. Some tests may require stopping certain medications (e.g., proton pump inhibitors for H. pylori) — check with your provider.
Biomarkers Tested
56Brown is normal; other colors may indicate abnormal gastrointestinal conditions.
Variations may indicate abnormal gastrointestinal conditions.
Mucous production may indicate infection, inflammation, or malignancy.
Detects bleeding in the digestive tract, indicating potential disease.
Imbalances in gut pH influence short-chain fatty acid production and their effects.
Presence may indicate infection, inflammation, or hemorrhage.
Measures the total number of white blood cells, your body's primary defense against infection. Elevated levels may indicate infection, inflammation, or immune disorders, while low levels can signal bone marrow problems or autoimmune conditions.
Presence may indicate maldigestion.
Presence may indicate maldigestion from too little gastric acid or reduced pancreatic output.
Presence may indicate maldigestion from gastric hypoacidity or diminished pancreatic output.
Elevated levels may indicate inadequate lipid absorption (steatorrhea).
Presence may indicate carbohydrate maldigestion.

Helps maintain microbiome balance.
Aeromonas are bacteria that can cause an acute diarrhoeal illness.
Campylobacter infection (campylobacteriosis) is a bacterial infection which most commonly causes gastroenteritis.
Salmonella infection usually results from ingestion of the bacteria from contaminated food, water or hands.
Shigella infection (shigellosis) is a type of gastroenteritis caused by Shigella bacteria.
This infectious bacteria can cause gastroenteritis and symptoms beyond the gut.
Opportunistic pathogen found in various environments.
Common in gut flora; rarely implicated in gastric disease.

E. faecalis is commonly found in the gut. In some cases E. faecalis can overgrow in the vagina and cause an infection, leading to symptoms such as abnormal vaginal discharge, odour, itching, and pain during sex or urination.
Part of normal gut flora; can be implicated in infections.

A gram-negative bacterium found in the gut, soil, and water. While part of normal intestinal flora, it can cause urinary tract infections, respiratory infections, and bloodstream infections in immunocompromised patients.
A gram-negative bacterium found in the gut and environment. It causes urinary tract infections, pneumonia, and antibiotic-associated haemorrhagic colitis. Can produce extended-spectrum beta-lactamases, conferring antibiotic resistance.
Candida albicans is a type of yeast that normally inhabits the vagina, but can sometimes overgrow and cause a yeast infection. This can occur due to factors such as antibiotic use, hormonal changes, or a weakened immune system. Symptoms may include itching, burning, and discharge.
C. parapsilosis can cause vaginal yeast infections, particularly in women who have received previous antifungal treatment. Symptoms may include itching, burning, and discharge. Treatment typically involves antifungal medications.
C. glabrata is a type of yeast that can cause vaginal yeast infections, particularly in women who are immunocompromised or have had antibiotics. Symptoms can include itching, burning, and discharge. C. glabrata can be more resistant to certain treatments compared to other Candida species.
Yeast found in various environments; opportunistic pathogen.
Common environmental yeast; not considered pathogenic.
Indicates potential yeast overgrowth.
Cryptosporidium is a microscopic parasite that causes the diarrhoeal disease cryptosporidiosis.
Symptoms of Giardia infection can occur with 3 to 25 days and may include diarrhoea, nausea, vomiting, pale greasy foul-smelling stools, stomach cramps, passing excess gas, bloating, weight loss and fatigue.
Amoebiasis is a parasitic disease (also known as amoebic dysentery) caused by infection with Entamoeba histolytica.
Some research suggests that people with IBS may be more likely to have Blastocystis hominis organisms in their stool.
The bacteria can be present in the gut for months or year and misdiagnosed as IBS.
