The question is not "which antibiotic." It is "does this need one at all."CLIA #45D2048957 · CAP #8722734 · Same-day results · Walk-ins welcome
Yes — and here the same-day result does something unusual: it often prevents a prescription rather than producing one. Norovirus needs no antibiotic. STEC must generally not receive one. Salmonella in an otherwise healthy adult is frequently not treated either. Knowing which of those you have, this afternoon, is what makes the decision safe.

What the result changes
| Finding | Typical direction (physician decides) |
|---|---|
| Norovirus / rotavirus | Supportive care. Antibiotics do nothing |
| STEC | Avoid antibiotics — HUS risk |
| Salmonella, healthy adult | Often not treated; treatment may prolong carriage |
| Shigella, Campylobacter (selected cases) | May be treated, per IDSA |
| Giardia, Cryptosporidium | Targeted therapy — parasites |
| C. difficile | Specific therapy — C. diff |
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 an antibiotic?
- Frequently not — and that is a real answer, not a brush-off. The physician tells you which case you are in.
- What about rehydration?
- Fluid and electrolyte replacement is the foundation of care in acute diarrhea. Severe dehydration needs an ER.
- How fast is the result?
- Same day at 4:30 PM; partner-network physician, 4:30–6:00 PM.
- Do I need insurance?
- No. Walk in Monday to Friday.
