Common does not mean simple. Most UTIs in women are treated without anyone knowing the organism.CLIA #45D2048957 · CAP #8722734 · Same-day results · Walk-ins welcome
A short female urethra makes UTI far more common in women — which has led to a culture of treating it blind. That works until it does not: the organism is resistant, or it is not E. coli, or it is not a UTI at all. A same-day molecular panel with resistance genes tells the physician what is actually there before the first dose.

The paths this can take

PresentationNext step
First uncomplicated episodeTest, treat same day with a targeted choice
Recurrent (2 in 6 months / 3 in a year)Recurrent UTI workup — AUA
Symptoms, culture always negativeCulture-negative UTI or a mimic
PregnantDifferent rules entirely
Fever + flank painEmergency department
Go to an emergency department, not a lab, if you have: fever with flank or back pain, shaking chills, persistent vomiting, or new confusion in an older adult. Those point to a kidney infection or sepsis and need urgent clinical care now.
We name drugs, never doses. Treatment statements follow IDSA, AUA and ACOG 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

Is it always E. coli?
Most of the time, not always — see mixed and non-E. coli infections.
Could it be an STI?
Symptoms overlap substantially. Both panels can be run from the same visit.
Why did the antibiotic not work?
Most commonly, resistance. That is exactly what the same-day panel reports.
Do I need an appointment?
No. Walk in Monday to Friday; arrive by 1:00 PM for a same-day result.
