Most labs send your sample out and you wait days for a result — then wait again for an appointment to do something about it. We run high-complexity molecular PCR in-house, so your result is ready this afternoon and a licensed physician can evaluate you the same day and treat you when it is clinically appropriate.
STD/STI · UTI · GI · Respiratory · Toxicology (for healthcare providers). Walk in. No insurance needed.

How the day works: drop off your sample by 1:00 PM → results ready at 4:30 PM → come back between 4:30 and 6:00 PM to see a licensed physician from our partner network (a few minutes away) if treatment is clinically appropriate. STAT results in 2 hours (sample by 3:00 PM). Mon–Fri, 9–5.

Five service lines, one high-complexity molecular lab

Four are for patients (tested and treated the same day) and also accept specimens from clinics. Toxicology is for healthcare organizations. Every image on this site is the actual molecular subject of the test — not stock photography.

STD / STI molecular fluorescenceSTD / STI

STD / STI

12-marker panel · treated the same day

Chlamydia, gonorrhea, syphilis, trichomonas, HSV-1/2, Mycoplasma genitalium, M. hominis, Ureaplasma, Gardnerella — plus HIV antibody and p24 antigen. Positive? You see a partner-network physician the same day; the slot is held for you.

UTI molecular fluorescenceUTI

UTI

Includes antibiotic-resistance genes

Urine culture takes 24–72 hours and can miss fastidious or polymicrobial infections — the usual reason a culture comes back negative while symptoms persist. Our PCR panel reports the same day, with resistance genes.

GI molecular fluorescenceGI

GI

Bacteria + viruses + parasites

Stool culture takes 2–4 days and will not find norovirus or most parasites. One molecular panel covers all three classes — which is what actually determines whether antibiotics belong in the picture.

GI testing →
Respiratory molecular fluorescenceRespiratory

Respiratory

One swab · multiple pathogens

Flu, COVID and RSV look alike, and rapid antigen tests miss early infection. CDC: flu antivirals work best within 48 hours of symptom onset — a day of diagnostic delay costs you half the window.

Toxicology (B2B)

LC-MS/MS definitive confirmation

For healthcare organizations. UDT and oral fluid with LC-MS/MS quantitation. A standard opiate immunoassay will not reliably detect fentanyl — a negative screen does not rule it out. 12–48 hour TAT.

Six things you can check for yourself

We are not going to tell you we are the best, fastest and most professional. Here are six claims, each with a source you can look up.

Results and treatment on the same day.
Sample by 1:00 PM → results at 4:30 PM → see a licensed physician 4:30–6:00 PM the same day if treatment is clinically appropriate. 2-hour STAT available. No waiting days for a result, no appointment weeks out.Monday–Friday, 9–5
A molecular test reads the genetic fingerprint. A rapid test looks for a marker.
Rapid tests detect antigens or antibodies — indirect evidence. PCR matches the pathogen's own nucleic acid sequence. CDC lists NAAT as the preferred method for chlamydia and gonorrhea.Source: CDC
A urine test cannot rule out a throat or rectal infection.
If your exposure was oral or anal and we only test urine, those sites were never tested. CDC notes NAAT is validated for pharyngeal and rectal specimens.Source: CDC STI Treatment Guidelines
Detected does not always mean treat.
Ureaplasma, M. hominis and Gardnerella are often colonizers. IDSA advises against treating asymptomatic bacteriuria in most people — and against antibiotics for STEC, which can raise HUS risk.Source: CDC / IDSA
A standard opiate screen will not find fentanyl.
Traditional immunoassays target the morphine scaffold. A negative opiate screen does not rule out fentanyl exposure. CDC: roughly 69% of overdose deaths in 2023 involved synthetic opioids (~73,000 deaths).Source: CDC Overdose Prevention

⚠ Go to the ER, not to us, if you have: trouble breathing, chest pain, blue lips, confusion; severe abdominal pain with fever or heavy rectal bleeding; fever with chills, flank pain and vomiting (possible kidney infection); or any infection during pregnancy.
🩺 About "same-day treatment": the partner-network physician is available, and you are seen the same day.
If treatment is warranted, you return the same day between 4:30 and 6:00 PM to see our licensed physician in our partner network. What they prescribe depends on your molecular result — the organism, its resistance profile, your symptoms, history, allergies and pregnancy status. Testing and treatment are handled by one lab on one day — not a referral out to somebody else next week.
Clinical content on this site is reviewed by our MD Laboratory Director — a role CLIA requires, whose name is on file in the CMS CLIA database (#45D2048957) and can be verified independently. Editorial policy →

Four steps, one day

No appointment. No referral. No insurance.

Text us, or just walk in

Text (713) 832-8892 with your symptoms or exposure and we will have the right panel and collection sites ready.

Sample collected in our partner network

Urine, swab, blood or stool, depending on the test. Run in-house — never sent out.

Results at 4:30 PM

Same day, if we have your sample by 1:00 PM. STAT in 2 hours (sample by 3:00 PM).

Come back for the doctor

If you need treatment, return between 4:30 and 6:00 PM and see a licensed physician — still the same day, not next week.

Two credentials — and you can verify both

CLIA is the federal authorization that makes clinical testing on human specimens legal. CAP is a voluntary, peer-based accreditation that goes well beyond the federal minimum. We hold both, and both numbers are public.

Where our clinical claims come from

Every clinical statement on this site points to a primary source you can open and read. That is the whole standard.

For clinics and healthcare organizations

Send-out molecular PCR (STD, UTI, GI, respiratory) and clinical toxicology (LC-MS/MS). Provider Portal ordering and results, EMR/LIS interfacing, courier pickup, custom panels. Compliance first: we do not pay for referrals, share revenue, or offer any financial inducement (AKS / Stark). Services are provided at fair market value under written agreement. We compete on turnaround time and testing quality — nothing else.

Questions people actually ask

How fast are results?

Sample by 1:00 PM and your results are ready the same day at 4:30 PM. STAT results in 2 hours (sample by 3:00 PM). We are open Monday through Friday, 9:00 AM to 5:00 PM, and closed weekends.

Can I really be treated the same day?

Yes — and this is the part most labs cannot offer. Your results are ready at 4:30 PM, and if treatment is clinically appropriate you come back between 4:30 and 6:00 PM to see a licensed physician from our partner network. You are still finished the same day, instead of waiting days for a result and then weeks for an appointment.

Do I need an appointment or insurance?

Neither. Walk in any weekday. No insurance required. Texting us at (713) 832-8892 before you arrive just lets us prepare the right panel and collection sites so you spend less time here.

What are your credentials?

CLIA certified (ID 45D2048957, Certificate of Accreditation, valid through February 20, 2028) and CAP accredited (#8722734, active), under an MD laboratory director. Both numbers can be verified independently — in the CMS CLIA database and with the College of American Pathologists.

How much does it cost?

Save up to 40% compared to a typical urgent-care visit and up to 90% less than an ER visit, with no facility fee. We are not the cheapest rapid-test box on the market — we are a high-complexity molecular lab that also treats you the same day.

Why is molecular PCR better than a rapid test?

A rapid test looks for antigens or antibodies. A molecular test matches the pathogen's own nucleic acid sequence — its genetic fingerprint — which is far more sensitive in early, low-load and asymptomatic infections. CDC lists NAAT as the preferred method for chlamydia and gonorrhea.

Is my visit private?

Yes. Testing and treatment are confidential and handled under HIPAA and applicable Texas law. No appointment, no referral, no waiting room full of people.

Can my clinic send specimens to you?

Yes. We serve as a reference lab for molecular PCR (STD/UTI/GI/respiratory) and clinical toxicology, with Provider Portal ordering and EMR/LIS interfacing. Compliance first: we do not pay for referrals, share revenue, or offer any financial inducement (AKS/Stark).

Get an answer today — not next week.
