A screening test is a question, not an answer. Confirmation is the part that gets skipped.CLIA #45D2048957 · CAP #8722734 · Same-day results · Walk-ins welcome
It depends entirely on what happens after it. Rapid screens are designed to be sensitive, not conclusive — they are meant to be confirmed. When a positive screen is handed over as a diagnosis, people get treated for infections they do not have, and keep the one they do.

A pattern we see

A patient arrives having been told at a free screening event that they have syphilis. We run confirmatory testing. The syphilis result does not hold up — and the full molecular panel finds a different pathogen entirely, the one actually causing the symptoms. The screening test was not lying. It was being read as something it was never designed to be.

The cost of a wrong answer is not measured in dollars. It is measured in the weeks you spend treating the wrong thing.

What "cheap" leaves out

Typically: extragenital sites, trichomonas, M. genitalium, and any confirmation step. If your throat and rectum were never swabbed, a negative result did not examine the places most likely to be positive — see the site guide.

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

So free testing is worthless?
No — free screening has genuine public-health value. What is dangerous is treating a screening result as a diagnosis, and stopping there.
I was told I have syphilis at a screening event. What now?
Come in for confirmatory serology before starting or continuing any treatment. See two-step serology.
Is your test more expensive?
It saves you up to 40% compared to urgent care and it actually answers the question. Text us for your specific situation.
How fast is confirmation?
Same day for the molecular panel; serology follows its own workflow and we will tell you honestly.
