At a glance
Digestive wellness testing measures stool and blood biomarkers, including fecal calprotectin, H. pylori stool antigen, celiac serology (tTG-IgA), pancreatic elastase, and key nutrient levels, to build an objective picture of gut inflammation, infection, digestion, and absorption. It is designed for adults with ongoing symptoms such as bloating, reflux, irregular bowel habits, or unexplained fatigue who want concrete data to review with their doctor. Tests can be ordered online without a doctor's visit, with blood draws at more than 2,100 US locations and at-home collection kits for some stool tests.
Best suited for
- Adults with ongoing bloating, gas, abdominal pain, or cramping
- People experiencing heartburn, reflux, nausea, or changing bowel habits (diarrhea, constipation, or alternating)
- Anyone with unexplained weight change, poor appetite, fatigue, brain fog, or skin issues
- Those with a family history of IBD, celiac disease, colon cancer, or peptic ulcer disease
- People who want baseline gut biomarkers to review with their doctor before changing their diet

Key biomarker ranges
Commonly used adult reference ranges for markers this panel measures, labs vary, so always interpret results against your lab's stated ranges and with your doctor.
Commonly used reference ranges place fasting glucose at 70–99 mg/dL; results vary with sleep, stress, and recent illness, and labs differ slightly.
| Zone | Range |
|---|---|
| Low | 50–70 mg/dL |
| Optimal | 70–100 mg/dL |
| Prediabetic range | 100–126 mg/dL |
| Diabetic range | 126–160 mg/dL |
Commonly used cutoffs: below 20 ng/mL deficient, 20–30 insufficient, 30–60 a frequently cited target band; season and supplementation move levels substantially.
| Zone | Range |
|---|---|
| Deficient | 0–20 ng/mL |
| Insufficient | 20–30 ng/mL |
| Sufficient | 30–60 ng/mL |
| High | 60–100 ng/mL |
Commonly used reference ranges differ by sex, roughly 30–200 ng/mL is typical, with men’s upper bounds higher; inflammation can raise ferritin and mask low iron.
| Zone | Range |
|---|---|
| Low | 0–30 ng/mL |
| Typical range | 30–200 ng/mL |
| Elevated | 200–400 ng/mL |
The importance of testing
Digestive symptoms are common, but they rarely explain themselves. Stool markers give you objective information about what is happening inside the gut: fecal calprotectin and lactoferrin measure intestinal inflammation and are often used to help distinguish inflammatory patterns from functional ones, a fecal immunochemical test (FIT) screens for hidden blood in the stool, and an H. pylori stool antigen or urea breath test screens for a bacterial infection associated with gastritis and peptic ulcers.
Blood serology adds another layer. A tTG-IgA test with total IgA is the primary screen for markers associated with celiac disease, with deamidated gliadin peptide antibodies available as additional serology. Pancreatic elastase-1 and fecal fat testing measure how well you digest and absorb food, while vitamin B12, vitamin D (25-OH), and iron studies (ferritin, TIBC) reveal the downstream nutrient status that malabsorption can affect.
A comprehensive metabolic panel, GGT, and bilirubin add liver and biliary context, and CRP or ESR (where offered) tracks systemic inflammation. Together these markers turn vague symptoms into specific results you can review with your doctor, and because results are stored in a private portal with trend charts, you can track how numbers move as you adjust diet, lifestyle, or therapy under your clinician's guidance.
Many blood test results return within 24–48 hours (stool test turnaround varies by assay), and HSA/FSA cards are accepted at checkout, so getting baseline data is a practical first step before your next appointment.

Do I need a doctor's visit to order digestive wellness tests?
No, you can order digestive wellness tests online without a doctor's appointment, because the partner lab provides the physician-authorized requisition. You order in minutes, complete your blood draw at one of 2,100+ locations (some stool tests use an at-home kit), and receive private results to review with your own clinician.
What do digestive wellness tests actually measure?
They measure stool and blood biomarkers tied to gut inflammation, infection, digestion, and nutrient absorption. Key examples include fecal calprotectin and lactoferrin (intestinal inflammation), FIT (hidden blood in stool), H. pylori stool antigen, celiac serology (tTG-IgA with total IgA), pancreatic elastase-1, and nutrient markers such as vitamin B12, vitamin D, and iron/ferritin. Results are flagged for you to review with your doctor, they are not intended to confirm any condition on their own.
Is direct-to-consumer lab testing available in every US state?
No, direct-to-consumer lab testing is restricted or prohibited in New York, New Jersey, and Rhode Island, so residents of those states may be blocked at the partner's checkout. Availability and turnaround can also vary by location, so check the partner page for options near you.
How fast will I get my results?
Many blood test results are available in 24–48 hours, while stool test turnaround varies by assay. Results appear in a secure online portal with trend charts so you can monitor changes over time and share reports with your clinician.
Can I pay with an HSA or FSA card?
Yes, HSA and FSA cards are accepted at checkout, and pricing is transparent cash-pay with no surprise insurance bills. The current promotion takes 20% off with code ULTADH; confirm final pricing on the partner page.
Which digestive test should I start with?
Common starting points include fecal calprotectin, an H. pylori test (stool antigen or breath), a celiac panel (tTG-IgA with total IgA), pancreatic elastase, and FIT, chosen based on your symptoms and family history. If you are unsure, a bundled Digestive Health panel covers multiple markers at once, and your doctor can help you interpret the results and decide on next steps.
