Its a feeling no one wants. A moment of panic, a new symptom, or a "what if" thought after a risky encounter. You're on holiday in beautiful Koh Samui, but suddenly, you can't relax. You need answers, and you need them now. You're searching for a "walk-in STD test."
The good news is that getting tested is a fast, simple, and 100% confidential process. The idea of a walk-in clinic is built for this exact situation: no long waits, no need to plan, just immediate peace of mind.
Let's walk you through the entire process, from what to expect when you walk in the door to how quickly you can get your results.
We understand that when you walk in for an STD test, your number one concern is privacy. Your visit, your consultation, and your results are a matter of absolute medical confidentiality. Our English-speaking doctors handle these tests every single day with professionalism and respect. We are here to help, not to judge.
The term "walk-in" is exactly what it sounds like.
The entire process is designed to be discreet, professional, and fast.
This is the most important question for your peace of mind. The time depends entirely on the test.
As you can see, you can get the results for an HIV or Syphilis screening before you even leave the clinic.
At Doctor Lamai Clinic, we use high-quality, 4th-generation rapid HIV tests. These are extremely accurate and can detect an infection as early as 2-4 weeks after exposure, giving you immediate, on-the-spot peace of mind.
This is a crucial concept. The "window period" is the time between a potential exposure and when a test can accurately detect an infection.
If your potential exposure to HIV was in the last 72 hours (3 days), do not wait. Come to our clinic immediately. This is a medical emergency.
You may be a candidate for PEP, a 28-day course of medication that can prevent the virus from taking hold. PEP must be started as soon as possible to be effective.

Can I get an anonymous STD test at your clinic?
Your visit is 100% medically confidential. While we need to create a medical file for you, your privacy is our highest priority. No information will be shared with anyone, ever, without your consent.
I don't have any symptoms. Should I still get a walk-in test?
Yes. Many of the most common STDs, including Chlamydia, Gonorrhea, and HIV, can have no symptoms at all for months or even years. If you've had unprotected sex or a new partner, a "peace of mind" check-up is a smart and responsible choice.
What is the fastest test I can get?
The rapid tests for HIV and Syphilis are the fastest. You get your results from a simple finger prick in just 15-20 minutes.
What if I test positive?
Our doctor will discreetly explain the results, what they mean, and provide you with immediate treatment (e.g., antibiotics for Chlamydia or Gonorrhea) or a prescription. We will support you with a clear, professional treatment plan.
How much does a walk-in STD test cost?
The cost depends on which tests you need. A rapid test for HIV is very affordable. A full-panel lab test for multiple infections will cost more. Our doctor will be transparent about all costs before any tests are run.
