What Is Actually on a GI Pathogen Panel?

Bacteria, viruses and parasites — in one molecular run. Culture covers only the first.CLIA #45D2048957 · CAP #8722734 · Same-day results · Walk-ins welcome
A molecular GI panel detects bacteria (Salmonella, Shigella, Campylobacter, Shiga toxin-producing E. coli, C. difficile toxin genes and others), viruses (norovirus, rotavirus, adenovirus, sapovirus) and parasites (Giardia, Cryptosporidium, Entamoeba histolytica) — the same day. Stool culture grows bacteria only, takes days, and will never find the norovirus that is actually making you ill.

What each category means for you
| Category | Examples | Why it changes management |
|---|---|---|
| Bacteria | Salmonella, Shigella, Campylobacter, STEC, C. difficile | Some are treated; STEC generally must not be — here is why |
| Viruses | Norovirus, rotavirus, adenovirus | Antibiotics do nothing. Knowing this stops an unnecessary prescription |
| Parasites | Giardia, Cryptosporidium, Entamoeba | Common cause of persistent diarrhea that culture never finds — see this |
The most valuable result a GI panel produces is often the one that tells the physician not to prescribe an antibiotic.
Go to an emergency department, not a lab, if you have: bloody diarrhea with fever, severe abdominal pain, signs of dehydration (dizziness, no urine for many hours), a rigid abdomen, or you are an infant, elderly, pregnant or immunocompromised and deteriorating. Those need urgent clinical care now.
We name drugs, never doses. Treatment statements follow ACG, AGA, IDSA and CDC guidance; dose and duration are a physician's decision.
Same day, start to finish. Sample by 1:00 PM → results at 4:30 PM → if treatment is clinically appropriate, a licensed physician in our partner network sees you between 4:30 and 6:00 PM, a few minutes away. That window is reserved for patients tested here, and your slot is held the moment we take your sample — the slot is held, not hunted. On your own, a same-day appointment is nearly impossible; at an urgent care, you wait in the queue. STAT: ~2 hours, sample in by 3:00 PM.
FAQ
- Do I need to collect stool at home?
- We will give you the collection kit and instructions. Bring it in by 1:00 PM for a same-day result.
- Can it detect C. difficile?
- The panel includes C. difficile toxin genes. Interpretation matters — colonization is common, particularly in healthcare settings. See C. diff testing.
- Is this the same as a stool culture?
- No — see panel vs. culture.
- How fast?
- Same day at 4:30 PM. STAT: about 2 hours.
