GI Testing Atlanta — The GI-MAP Comprehensive Stool Analysis
Why Standard GI Testing Falls Short
If you’ve been looking for GI testing Atlanta because your regular doctor can’t figure out what’s wrong with your gut — you’re in the right place. Standard bloodwork doesn’t look deep enough. A CBC and metabolic panel won’t catch bacterial overgrowth, yeast, hidden infections, or intestinal permeability. If you’ve been Googling things like parasite testing near me or leaky gut testing with no luck, you’re not alone. Most doctors simply aren’t running the right tests — like a GI-MAP stool test or real microbiome testing in Atlanta.
We use the GI-MAP — the GI Microbial Assay Plus from Diagnostic Solutions Laboratory — because it gives us a real look at what’s happening inside your digestive tract. Your gut bacteria, enzyme output, inflammation markers, parasites, yeast, and H. pylori — all from one sample you collect at home. It’s the kind of microbiome testing Atlanta patients have been asking us about for years.
At Taylor Medical Group in Sandy Springs, we don’t guess. We test first and treat based on what your results actually show. Our functional medicine approach gets to the root cause — not just your symptoms. If you’re in Atlanta, Dunwoody, Buckhead, Brookhaven, or Chamblee and you’re tired of being told “it’s just IBS” — come see us. We’ll figure out what’s really going on.

Who Needs GI Testing in Atlanta?
What Our GI Testing in Atlanta Looks For
Your gut does a lot more than digest food. It houses about 70% of your immune system. It produces neurotransmitters like serotonin that affect your mood. It communicates directly with your brain through what’s called the gut-brain axis. When your gut is off, everything is off — your energy, your mood, your skin, your immune system, even your ability to think clearly.
When we run GI testing in Atlanta with the GI-MAP, we’re checking six major areas — everything from digestion and microbiome balance to parasite detection and leaky gut testing with zonulin:
Digestion & Absorption
Are you breaking down food properly? The GI-MAP measures pancreatic elastase-1 — your enzyme output — along with steatocrit, which tells us whether fat is being absorbed or passing straight through. If your body isn’t getting nutrients from the food you eat, this is where it shows up.
Gut Inflammation
Calprotectin tells us whether your intestines are inflamed, and eosinophil activation protein points to allergic or parasite-driven inflammation. Together they help distinguish irritable bowel syndrome (IBS) from inflammatory bowel disease (IBD) like Crohn’s or ulcerative colitis.
Microbiome Balance
Your gut has trillions of bacteria — some helpful, some harmful. The GI-MAP measures your keystone bacteria (like Lactobacillus and Bifidobacterium) alongside the opportunistic overgrowth species. Dysbiosis — an imbalance between them — is linked to autoimmune disease, depression, skin problems, and weight gain.
Infections & Parasite Testing
If you’ve been searching for parasite testing near me, this is it. The GI-MAP checks for the parasitic pathogens — Giardia, Cryptosporidium, Cyclospora and Entamoeba histolytica — along with protozoa like Blastocystis hominis and Dientamoeba fragilis, worms including roundworm, both hookworms, whipworm and tapeworm, and microsporidia. It also covers pathogenic bacteria, gastroenteritis viruses, H. pylori, and yeast overgrowth including Candida. You’d be surprised how many people are walking around with gut infections they don’t know about — and how much better they feel once we find and treat them.
Leaky Gut Testing (Intestinal Permeability)
We add zonulin to the panel, which tells us if your intestinal lining has become too permeable — letting food particles, bacteria, and toxins leak into your bloodstream. This triggers inflammation all over the body and is often a root cause of leaky gut syndrome.
Gut Immune Function
Secretory IgA is your gut’s own antibody defence — the first line against anything you swallow. Anti-gliadin IgA shows whether your immune system is reacting to gluten. Both are measured on the GI-MAP, and neither appears on a standard stool test.
The GI-MAP Stool Test — GI Microbial Assay Plus
We use the GI-MAP from Diagnostic Solutions Laboratory for GI testing in Atlanta. It is built on quantitative PCR — qPCR — which reads the actual DNA of the organisms living in your gut and reports how much of each one is there. Not a guess, not a rough growth on a culture plate. A number.
Here’s what makes the GI-MAP different from the stool test your primary care doctor might order:
It reads DNA, not cultures. A standard stool culture can only report what grows in a dish, and most gut organisms will not grow in one. qPCR finds bacteria, yeast and parasites by their genetic signature whether they grow or not — which is why it catches infections that culture-based testing misses entirely. If you want microbiome testing in Atlanta that actually means something, this is it.
It quantifies, and that is the whole point. Most stool tests tell you an organism is present or absent. qPCR tells us how much — a true number, measured against a reference range, and more precise for this purpose than standard PCR, culture, microscopy, or DNA sequencing. That distinction matters more than it sounds. A trace of an organism and an amount that means active infection look identical on a positive-or-negative result. Many of the microbes in your gut are perfectly normal in small numbers and only cause trouble when they overgrow, so the number is what separates a finding worth treating from one worth leaving alone.
The results hold up. Diagnostic Solutions validates its molecular quantification assays to meet or exceed FDA standards and runs rigorous quality control, which is what makes the results reproducible — the same sample gives the same answer. That reliability is the reason a retest means something: after treatment, we can see whether a parasite has actually cleared and whether dysbiosis has genuinely improved, rather than assuming it has because you feel better.
H. pylori, properly. Studies suggest nearly half the world’s population may carry H. pylori, and most carriers have no symptoms at all — but it has a causative role in ulcers, chronic gastritis and stomach cancer, so knowing which kind you are carrying matters. The GI-MAP doesn’t just report whether it is there. It reports the virulence factors: the specific genes that separate a strain with real disease potential from one that may need no treatment at all. It also reports antibiotic resistance genes by class, so if treatment is needed we know in advance which drugs that strain is likely to shrug off. Worth knowing: those resistance genes are read across every organism in the sample, not just H. pylori — bacteria swap DNA readily under stress, so resistance anywhere in your gut is reason enough to avoid that class of drug.
One sample, collected at home. No three-day collection, no refrigeration, no trips to a lab. One sample, at room temperature, in the vial provided.
Depending on what we’re looking for, we can add zonulin for leaky gut testing, a fecal gluten peptide test that shows whether gluten has been eaten in the last two to four days, a universal antibiotic resistance panel, or StoolOMX — 25 bile acids and 9 short-chain and branch-chain fatty acids, which tell us how well your bacteria are fermenting fiber and how sound your gut barrier is.
The organisms are read by qPCR. The intestinal health markers — pancreatic elastase-1, secretory IgA, anti-gliadin IgA, eosinophil activation protein, calprotectin and zonulin — are measured by ELISA on the same sample, so digestion, inflammation, immune function and gut barrier all come back together with the microbiology rather than as separate tests on separate days.
What the GI-MAP Report Actually Shows
The report is organised into groups, and each one answers a different question about your gut. Here is what we are reading when we sit down with your results.
Pathogens. The bacteria, parasites and viruses known to cause intestinal infection. One honest caveat we always give patients: a positive finding does not automatically mean you are ill from it. Your own health, how transient the organism is, and whether the strain carries virulence genes all decide whether it is actually causing your symptoms. That is a conversation, not a line on a page.
Commensal and keystone bacteria. The trillions of organisms that are supposed to be there. They pull nutrients and energy out of your food, hold your gut barrier together, make vitamins your body needs — biotin and vitamin K among them — and physically crowd out organisms that would otherwise take hold. When these are depleted, everything else gets easier for the wrong microbes.
Opportunistic and overgrowth microbes. Bacteria that most people carry without trouble, which cause problems when they get out of hand — diarrhoea, loose stools, abdominal pain, sometimes constipation. Overgrowth usually follows something that knocked down the commensal bacteria first: a poor diet, a course of antibiotics, a parasitic infection, a stretch of illness. And if intestinal permeability is present as well, these are the organisms that can leave the gut and cause trouble elsewhere in the body.
Fungi and yeast. Fungal organisms are normal residents of the digestive tract; overgrowth is what causes illness. One limitation worth stating: fungal overgrowth can be local. Candida can be high in the large intestine and perfectly normal in the small intestine, or the reverse — so where we suspect fungal overgrowth and the stool test does not settle it, we may add a urinary D-arabinitol or Candida antibody test to see the whole picture.
Parasites. Pathogenic parasites and protozoa, named individually in the FAQ below. Finding one is only half the job — we also want to know where you picked it up, because an exposure that is still in your life will simply reinfect you after treatment.
Intestinal health markers. Beyond the microbes: digestion, absorption, inflammation, gluten reactivity, gut immune function and intestinal permeability, measured by clinically validated ELISA assays on the same sample.
Parasites Are Not Just a Travel Problem — They’re a U.S. Food and Water Problem
Most people assume you only pick up a parasite abroad. That hasn’t been true for a long time. Parasitic outbreaks happen here, in the United States, from contaminated food and contaminated water — and they happen every year.
The clearest example is happening right now. The CDC issued a health advisory in July 2026 over 1,645 confirmed cases of cyclosporiasis across 34 states since the first of May — against 249 cases by the same point the year before — with several thousand more cases still under review. Outbreaks like this are repeatedly traced back to contaminated fresh produce: the salad greens, herbs and berries that health-conscious people eat the most of. And the CDC says plainly that cyclosporiasis is underdiagnosed and underreported, so the real number is higher than the one being counted.
It isn’t only food. Cryptosporidium is the leading cause of waterborne outbreaks in this country — swimming pools, water parks, splash pads — because it survives chlorine at the levels pools are normally treated at. Giardia is the most common waterborne parasite in the United States. Neither requires a plane ticket.
Here’s the part that matters for you. These infections routinely go unfound, because the standard stool test most doctors order looks for organisms under a microscope — and a technician has to spot something small, in a small sample, on a slide. Parasites shed intermittently, so they are simply not there on the day you collected. The GI-MAP looks for parasite DNA instead, which is present whether or not an organism happened to land on that slide, and it reports how much. That is the difference between “your stool test was normal” and an actual answer.
If you have had persistent diarrhoea, cramping, loss of appetite or unexplained weight loss since a summer of salads, a trip to a water park, or a stretch of well water — and you were told your tests were fine — this is worth doing properly. Come see us.
Why the GI-MAP Is Ordered by a Doctor, Not Bought Online
You will find companies selling stool test kits straight to the public. The GI-MAP is a diagnostic tool, and it is used with patients who have serious illness — autoimmune disease, thyroid disease, parasitic infection, Crohn’s disease, among others. A result on its own is a page of numbers. What makes it useful is a physician reading those numbers against your history, your symptoms, your medications and your other laboratory work, and deciding what is urgent, what is already fine, and what should wait until an infection is cleared.
That is the part you cannot buy in a box, and it is the part that turns a test result into a treatment plan.
Who Should Get GI Testing in Atlanta?
If you’re in the Atlanta area and dealing with any of these, GI testing Atlanta should be on your radar:
Chronic Bloating & Gas
IBS / IBD
Food Sensitivities
Diarrhea / Constipation
Acid Reflux / GERD
Autoimmune Disease
Skin Issues (Acne, Psoriasis, Eczema)
Depression & Anxiety
Chronic Fatigue
Brain Fog
Diabetes & Weight Loss Issues
Recurrent Infections
Here’s what most people don’t realize: gut problems don’t always show up as stomach problems. If you have skin issues, joint pain, brain fog, mood problems, or you keep getting sick — your gut could be the root cause. We see this all the time. Many patients who come in for parasite testing near me or leaky gut testing are surprised to learn their “unrelated” symptoms — chronic fatigue, eczema, anxiety — all trace back to what’s happening in their gut. That’s why proper GI testing and microbiome testing in Atlanta matters so much. Patients focused on longevity and prevention also benefit from knowing their gut health baseline.
How GI Testing Atlanta Works at Taylor Medical Group
1
Consultation
You’ll meet with one of our doctors to go over your full health history, symptoms, diet, medications, and what you’ve already tried. This helps us decide exactly which tests to order and which add-ons your case calls for. This is our Medical Testing New Patient Consult — thirty minutes with the doctor, $175 — and it is required before any test kit is issued.
2
Collection at Home
You’ll get a GI-MAP collection kit to take home. One sample, kept at room temperature in the vial provided, shipped back in the prepaid mailer. No three-day collection and nothing to refrigerate.
3
Results Review
The lab reports in about 7 to 10 business days once your sample arrives. We’ll sit down with you and walk through every finding — what’s normal, what’s not, and what it means for your health. No jargon. Just plain English.

Personalized Treatment Plan
Based on your results, we build a treatment plan that might include diet changes, specific supplements, probiotics, antimicrobials, digestive enzymes, or IV therapy to correct deficiencies your gut can’t absorb on its own.
What Happens After Your Results Come Back
This is where things get interesting. Once we know what’s going on, we can actually fix it — and the approach is different for every person.
We can prescribe, and that matters more than it sounds. We are a medical practice, not a supplement company and not a laboratory selling kits. When your results call for it, the doctor can prescribe antiparasitic and antiprotozoal medication for a confirmed parasite, antibiotics for pathogenic bacteria, and antifungal medication for fungal overgrowth — the same medicine you would be given anywhere else, except that here it is chosen against a named organism and a measured quantity rather than a guess. Which drug, at what dose, for how long, is a clinical decision made for you at your results visit.
Not everything needs a prescription. For milder overgrowth, we often use botanical antimicrobials, and for many patients the better answer is rebuilding the terrain rather than attacking it. We’ll tell you plainly what you’re dealing with.
If we find yeast overgrowth or bacterial infections, we guide treatment by how much of the organism the GI-MAP actually measured, not by guesswork. Where H. pylori is involved, the resistance genes on your report tell us which antibiotics that particular strain is likely to shrug off — which is the difference between a course that works first time and one that fails and has to be repeated.
If your digestive enzymes are low, we add enzyme support so your body can actually break down and absorb the food you’re eating. Where a parasite or yeast overgrowth is part of the picture, the doctor may also use ParaDix, our own physician-formulated parasite and candida cleanse, alongside or instead of a prescription, depending on what your results show.
If your microbiome is out of balance, we rebuild it — with the right probiotic strains (not a random one from the grocery store), prebiotic foods, and diet changes that feed your good bacteria.
If our leaky gut testing confirms intestinal permeability, we work on healing the gut lining with nutrients like glutamine, zinc carnosine, and anti-inflammatory support. Many patients also benefit from glutathione IV therapy for detoxification and IV vitamin therapy to correct nutrient deficiencies caused by poor absorption.
We retest after treatment to make sure things are improving—not just assume they are. Because the GI-MAP reports numbers rather than a simple positive or negative, a retest shows us exactly how far each organism has moved.
What GI Testing in Atlanta Costs
A consultation with the doctor comes first. We do not hand out test kits without one — which test to run, which add-ons your case calls for, and how to read the result against your history are all decisions that need a physician, and that is where the value of this testing actually lies.
Step 1 — Medical Testing Consultation
$175
Thirty minutes with the doctor. Your full history, your symptoms, what you have already tried — and the decision about which testing to order. This visit is required before any test kit is issued.
Step 2 — The GI Mapping Test Kit
$400
The GI-MAP kit itself. You collect one sample at home and mail it to the laboratory in the prepaid mailer. Your results review with the doctor is scheduled as soon as the report comes back.
We are a cash-pay practice. We do not accept insurance, and payment is by cash or credit card. Our patients tell us it is money well spent, because after years of being told everything looks normal they finally have an answer they can act on.
Frequently Asked Questions
Is this the same as the stool test my regular doctor orders?
Not even close. Standard stool tests look for a handful of common infections and report them as present or absent. The GI-MAP uses DNA-based qPCR to measure how much of each organism is there, along with your digestive enzyme output, inflammation markers, gut immune function, and intestinal permeability. You’re getting microbiome testing, leaky gut testing through zonulin, and thorough parasite screening — all in one panel. It’s a completely different level of testing than what you’ll get at a regular doctor’s office.
Do I have to come into the office to collect the sample?
No. You collect one sample at home using the kit we give you. Everything you need is in the box — the collection vial, instructions, and a prepaid shipping label. It stays at room temperature and you mail it directly to the lab.
How long does it take to get results?
About 7 to 10 business days after the lab receives your sample, so roughly two weeks from the day you mail it. We’ll call you to schedule a results review appointment as soon as they come in.
How much is it, and how do I pay?
The GI Mapping test is $400, and the required consultation is $175. We are a cash-pay practice — we do not accept insurance — and we accept cash or credit card.
Can GI testing in Atlanta help with problems outside my gut?
Absolutely. This surprises a lot of people — but we regularly see gut problems causing or worsening skin conditions, joint pain, depression, anxiety, brain fog, autoimmune flares, and chronic fatigue. Leaky gut testing often reveals the missing piece for patients with autoimmune issues. Once we fix the gut, these other conditions often improve — sometimes dramatically.
Do I need to stop any medications or supplements before the test?
If you’re taking antibiotics, antifungals, or antiparasitic medications, you should wait at least 14 days after your last dose — 28 days is even better. We’ll go over everything with you before you collect.
Where can I get reliable parasite testing near me?
If you’re in the Atlanta area and searching for parasite testing near me, this is exactly what we do. The GI-MAP uses qPCR DNA analysis for parasite testing rather than looking for organisms under a microscope, which means it catches infections that standard lab tests miss. DNA-based testing is far more sensitive than what most local labs offer, and it tells us how much is there — not just whether something was spotted on a slide.
Which parasites does the GI-MAP actually test for?
The parasitic pathogens are Giardia, Cryptosporidium, Cyclospora, and Entamoeba histolytica. The protozoa are Blastocystis hominis, Dientamoeba fragilis, Pentatrichomonas hominis, Chilomastix mesnili, Endolimax nana and Entamoeba coli. The worms are Ascaris lumbricoides (roundworm), Necator americanus and Ancylostoma duodenale (hookworms), Trichuris trichiura (whipworm), and Taenia species (tapeworm). Microsporidia are covered as well. Two things worth saying plainly: this is a defined panel, so a parasite outside this list will not be found on it — and several of the protozoa are carried by healthy people without causing any trouble at all, which is why your results are interpreted alongside your symptoms rather than treated on sight.
What makes your microbiome testing in Atlanta different from a regular stool culture?
A regular stool culture can only grow a small number of organisms in a lab dish, and a great many gut bacteria will not grow in one at all. The microbiome testing we do in Atlanta with the GI-MAP reads DNA instead, so it finds and measures those organisms whether they grow or not. It gives us a far more complete and accurate view of what’s living in your gut.
What is the GI-MAP, exactly?
GI-MAP stands for GI Microbial Assay Plus. It’s a comprehensive stool panel from Diagnostic Solutions Laboratory that uses quantitative PCR to identify and measure the bacteria, yeast, parasites, and viruses in your digestive tract, along with markers for digestion, inflammation, gut immune function, and intestinal permeability. Diagnostic Solutions is the only laboratory in the United States that uses qPCR exclusively for comprehensive stool testing, which lets the report provide true quantities rather than a positive or negative—the difference between a trace of an organism and an amount that indicates active infection. Patients often search for it as the GI Map test or GI mapping.
If something shows up positive, does that mean it’s making me sick?
Not necessarily, and we would rather say so up front than have you alarmed by your own report. Plenty of people carry organisms without symptoms. Whether a finding matters depends on how much of it is there, how healthy you are otherwise, whether the strain carries virulence genes, and whether it lines up with what you actually came in complaining about. That judgment is why the results review is an appointment, not an email.
Does the test measure toxins?
Not directly. Because the GI-MAP reads DNA, it reports the level of strains that carry toxin genes — not the amount of toxin those organisms may be producing at the moment. It’s a meaningful distinction, and one we’ll explain when it comes up in your results.
If you find a parasite or an infection, can you actually treat it?
Yes. We’re a medical practice, so the doctor can prescribe antiparasitic, antiprotozoal, antibiotic, and antifungal medication when your results call for it — and choose it based on the specific organism found and how much of it, rather than treating blind. We also use botanical antimicrobials where those are the better fit. A laboratory that sells you a kit cannot do any of this, and neither can a supplement company.
Can I just buy a stool test kit online instead?
Some companies do sell stool testing directly to the public. The GI-MAP is a diagnostic tool used with patients who have real illness — autoimmune disease, thyroid disease, parasitic infection, Crohn’s — and the value is not in the pages of numbers; it’s in a physician reading them against your history, your symptoms, and your other laboratory work, then deciding what to treat first and what to leave alone. That is what you’re paying for here, and it’s what turns a result into a plan.
Can I order just part of the panel?
Yes. If your case points somewhere specific, the lab offers narrower profiles — a GI Pathogens Profile, an H. pylori Profile, stool zonulin on its own, calprotectin on its own, or the gluten peptide test. We’ll decide together at your consultation whether the full GI-MAP or one of the focused panels is the right place to start.
Ready to Find Out What’s Going On in Your Gut?
Stop guessing. Stop Googling. If you need real answers — GI-MAP testing, microbiome testing, leaky gut testing, or parasite testing near me — we’ve got you covered. We see patients from Sandy Springs, Dunwoody, Buckhead, Brookhaven, Chamblee, and all over metro Atlanta.
