How GI Effects + Microbiomix works
You collect stool samples at home with the kit and mail them to the lab. The lab measures markers of digestion and absorption, intestinal inflammation, gut immune activity and the makeup of gut microbes using DNA-based sequencing. Your clinician reads the results together with your symptoms to decide what to treat, what to recheck and what needs specialist care.
Who it’s for, and who it isn’t
May be a fit
- Adults with ongoing gut symptoms such as bloating, gas, loose stools, constipation or discomfort
- People whose gut symptoms began or worsened alongside midlife hormone changes, weight change or new medicines
- People who want inflammation and digestion markers, not just a bacteria list
- People who have had, or are arranging, appropriate medical evaluation for red-flag symptoms
Usually not a fit
- Anyone with rectal bleeding, black stools, anemia, unexplained weight loss or severe pain: seek medical care first
- Replacing colonoscopy or other colorectal cancer screening
- Diagnosing IBS or inflammatory bowel disease on its own
- People without symptoms who simply want a microbiome snapshot (Gut Biome Analysis may fit better)
What’s included
- Clinician order with personalized preparation instructions
- At-home stool collection kit with return shipping
- Analysis by a CLIA-certified laboratory
- Clinician review of results with your symptoms and history
- Online visit to agree next steps, including referral where needed
- No membership fee
Possible side effects
- No physical side effects; collection is non-invasive
- Pausing some supplements or medicines before collection may temporarily bring back symptoms (only pause with your clinician's approval)
- Borderline findings can lead to further tests or referrals
This isn’t a complete list. Your clinician reviews risks, interactions and warnings with you before prescribing. In an emergency, call 911.
What the evidence says
Some markers in this panel, such as fecal calprotectin, are widely used in gastroenterology to help tell inflammatory bowel disease from functional problems like IBS. Microbiome sequencing is less established: a 2025 international consensus in The Lancet Gastroenterology and Hepatology found the evidence for clinical usefulness of microbiome testing scarce. The panel is a laboratory-developed test that the FDA has not reviewed.
What this panel adds over a microbiome test
A basic microbiome test tells you which bacteria are there. This panel also asks how your gut is working. It combines several groups of markers in one kit:
- Digestion and absorption: markers that reflect how well you break down and absorb fats, proteins and carbohydrates, including pancreatic function
- Inflammation: fecal calprotectin and related markers that rise when the intestinal lining is inflamed
- Gut immune activity: markers such as secretory IgA
- Microbial makeup: bacteria and other organisms identified by DNA-based methods, with an expanded Microbiomix sequencing report
When it makes sense
This panel is meant for people with symptoms. Bloating that builds through the day, swings between constipation and loose stools, new food sensitivities or general gut discomfort are common reasons. Midlife adds its own layers: changing estrogen and progesterone, new medicines such as GLP-1s or acid reducers, and shifts in sleep, stress and activity can all affect digestion.
If you have no symptoms and are simply curious about your gut bacteria, Gut Biome Analysis is a lower-cost option.
Red flags come first
Some symptoms need a medical evaluation before, or instead of, a stool panel. The National Institute of Diabetes and Digestive and Kidney Diseases lists anemia, rectal bleeding, bloody or black stools and weight loss as signs that point to something other than IBS. These may call for blood tests, endoscopy or colonoscopy.
If any of these apply to you, your clinician will help you arrange appropriate in-person care. A stool panel is never a substitute for that.
How your clinician uses the inflammation markers
Calprotectin is a protein released by white blood cells in the gut lining. In gastroenterology it is commonly used as a first step to help separate inflammatory conditions, such as Crohn's disease or ulcerative colitis, from functional problems like IBS, where the lining is not inflamed. A normal result can be reassuring; a clearly high one needs follow-up.
Mildly raised results can have everyday explanations, including recent infections and some medicines such as anti-inflammatory painkillers. Your clinician may repeat the test or ask about these before recommending a referral. Either way, the decision is about the next sensible step, not a diagnosis from one number.
What the results can and can't tell you
The panel can point toward patterns such as signs of inflammation, poor fat digestion or an imbalance in gut organisms. A clearly raised calprotectin, for instance, usually leads to a gastroenterology referral rather than a diet plan.
It cannot diagnose IBS, which NIDDK notes is diagnosed mainly from symptoms and history. It cannot confirm inflammatory bowel disease or celiac disease, which need specific tests and often a biopsy. It also cannot detect colorectal cancer; the National Cancer Institute advises that average-risk adults start screening at 45.
Expect the microbiome portion to be the least certain part. Experts agree the science linking specific bacterial patterns to specific treatments is still developing.
Preparing for collection
Antibiotics, probiotics, antacids, digestive enzymes, bismuth and some other medicines can change results. Your instructions will explain what, if anything, to pause and for how long. Never stop a prescribed medicine without your clinician's agreement.
Collect when your symptoms are typical for you, and note anything unusual that week, such as travel, illness or a big diet change, so it can be considered when reading the results.
If you take a GLP-1 medicine, mention it, because slower stomach emptying can change bowel habits and may explain some of your symptoms.
After your results
You review the report with your clinician in an online visit. Common next steps include targeted diet changes, treating a specific finding, rechecking after a period of change, or referral to a gastroenterologist. The goal is a short, sensible plan, not a long list of supplements.
GI Effects + Microbiomix is a laboratory-developed test run by a CLIA-certified lab and has not been cleared or approved by the FDA. The price is $1,095, one-time, confirmed during your eligibility review. It is generally not covered by insurance, and there is no membership fee.

GI Effects + Microbiomix: common questions
How is this different from Gut Biome Analysis?
Gut Biome Analysis profiles bacteria only. This panel adds digestion, absorption, inflammation and gut immune markers, so it suits people with symptoms.
Can it diagnose IBS or IBD?
No. IBS is diagnosed from symptoms and history, and IBD needs specialist testing. A raised inflammation marker would usually lead to a gastroenterology referral.
Do I need to stop probiotics or medicines first?
Possibly. Your instructions will say what to pause and when. Don't stop any prescribed medicine without checking with your clinician.
Is the sample collected at home?
Yes. The kit includes everything needed to collect and mail the samples to the lab.
What if something abnormal turns up?
Your clinician explains it and agrees a plan with you, which may include treatment, retesting or a referral for in-person care.
Does gut health really affect weight and energy?
Research links the gut to metabolism and wellbeing, but the connections in any one person are hard to pin down. Results are used as context, not as a single explanation.
Will insurance cover it?
Generally not. HealifyMD does not bill insurance; HSA or FSA funds may apply depending on your plan.
