You have burning, urgency, and a course of antibiotics that did not work. Or a culture that came back "no growth" while you clearly have something. Both are common, and both have the same root cause: urine culture takes 24–72 hours and it does not find everything. Fastidious organisms, polymicrobial infections — culture can miss them entirely.
We run a molecular PCR panel instead. It identifies the organism directly from its nucleic acid, and it detects antibiotic-resistance genes at the same time. So ythe partner-network physician learns two things on the first visit: what this is, and what it is likely to resist — instead of guessing, waiting three days, and guessing again.
Sample by 1:00 PM → results at 4:30 PM → physician 4:30–6:00 PM. Same day. Walk in.

Culture vs. molecular PCR
| Urine culture | Molecular PCR (ours) | |
|---|---|---|
| Time to answer | Typically 24–72 hours; susceptibility takes longer still | Same day — sample by 1 PM, result at 4:30 PM (STAT: 2 hours) |
| Fastidious organisms | Frequently missed | Detected |
| Polymicrobial infection | Often masked by the dominant grower | Detected |
| Resistance information | Requires separate susceptibility testing | Resistance genes reported with the organism |
| "Culture-negative" symptoms | The usual dead end | Far more likely to find the cause |
A negative culture with real symptoms is not proof there is no infection. It is often just proof that culture could not grow what is there. Culture-negative UTI, explained →
One honest caveat about resistance genes
A resistance gene is a fast risk signal — it is not a full susceptibility panel. Molecular testing tells ythe partner-network physician what the organism is and what it is likely to resist, quickly. Culture and susceptibility testing directly measure how the organism responds to specific drugs. The two are complements, not competitors, and we will say so rather than oversell what a gene result can do. Resistance gene testing →
If your UTIs keep coming back
AUA defines recurrent UTI as 2 or more episodes in 6 months, or 3 or more in 12 months. If that is you, the question is no longer "which antibiotic" — it is why the same thing keeps happening: reinfection, a persistent reservoir, a stone, retained urine, or a resistant organism that empiric therapy never covered. Molecular testing with resistance genes is how you stop guessing. Recurrent UTI →
Go to the ER, not to us, if: you have fever, chills, flank or back pain, nausea and vomiting (possible kidney infection); low blood pressure, a racing pulse, confusion, or dropping urine output (possible urosepsis); a known stone or hydronephrosis with infection (antibiotics cannot substitute for drainage); or you are pregnant.
FAQ
- Why was my urine culture negative?
- Culture can miss fastidious organisms and polymicrobial infections, and prior antibiotics can suppress growth. A molecular panel looks for nucleic acid directly and covers more organisms.
- How fast are results?
- Sample by 1:00 PM, results at 4:30 PM the same day. STAT results in 2 hours if collected by 3:00 PM.
- Do you test for antibiotic resistance?
- Yes — the panel reports resistance genes alongside the organism, so ythe partner-network physician does not have to wait days for susceptibility results.
- Is a resistance gene the same as a susceptibility test?
- No, and we will not pretend otherwise. Genes are a fast risk signal; culture and susceptibility directly measure drug response. Ythe partner-network physician uses both.
- Can I be treated the same day?
- Yes. A licensed physician sees you between 4:30 and 6:00 PM the same day.
- What counts as recurrent UTI?
- Per AUA: 2 or more symptomatic episodes in 6 months, or 3 or more in 12 months.
