STD Testing in Koh Samui: Complete Guide to HIV, Syphilis, Chlamydia & More


Sexual health testing is one of the most requested services at Samui Home Clinic. Whether you are a tourist, expat, or long-term resident, we offer confidential, professional, and non-judgmental STD and STI testing in Koh Samui. This guide explains everything you need to know.

Why Get Tested in Koh Samui?

Koh Samui is a major nightlife and entertainment destination. Unprotected sex — even a single incident — can transmit STIs including HIV, syphilis, chlamydia, gonorrhoea, and herpes. Many STIs have no symptoms, meaning you can be infected and not know it. Early diagnosis means earlier treatment and less risk of complications or transmission to others.

What STIs Can Be Tested at Samui Home Clinic?

  • HIV (types 1 and 2) — rapid test and 4th generation antigen/antibody

  • Syphilis (rapid and confirmatory)

  • Chlamydia and Gonorrhoea (urine PCR or swab)

  • Hepatitis B and C

  • Herpes simplex virus (HSV-1 and HSV-2)

  • Trichomonas vaginalis

  • Mycoplasma genitalium

  • HPV (where applicable)

  • Full sexual health screen (comprehensive panel)

How Does Testing Work?

Testing at our clinic is quick, private, and straightforward:

  • Walk in or book online — no appointment usually needed

  • Speak with our doctor or nurse in complete confidence

  • Blood draw, urine sample, or swab depending on the test required

  • Results available within 30 minutes to 24–48 hours depending on test

  • Full counselling provided with all results

HIV Testing: What You Need to Know

HIV is the most commonly requested test at our clinic. We offer:

  • Rapid HIV test (result in 20–30 minutes) — highly accurate for exposures more than 4 weeks ago

  • 4th generation HIV combo test (Ag/Ab) — detects infection from as early as 2–4 weeks

Important: No HIV test can detect infection on the day of exposure. There is a window period. Our doctors will advise you on timing and whether a repeat test is needed.

PEP and PrEP: Emergency and Preventive HIV Treatment

If you have had a potential HIV exposure in the last 72 hours, you may be eligible for Post-Exposure Prophylaxis (PEP) — an emergency medication that significantly reduces the risk of HIV infection. We stock PEP at our clinic and pharmacy. Time is critical — contact us immediately.

PrEP (Pre-Exposure Prophylaxis) is a daily pill that prevents HIV infection in HIV-negative people at ongoing risk. We prescribe and supply PrEP at Samui Home Clinic and our pharmacy.

Is Testing Confidential?

Absolutely. All testing at Samui Home Clinic is completely confidential. We do not share your results with anyone — not your hotel, your travel insurance, your employer, or your government — without your explicit consent. You may use a first name only if you prefer.

Treatment: What Happens if I Test Positive?

Our doctors are experienced in managing all common STIs. Most STIs — including syphilis, chlamydia, gonorrhoea, and trichomonas — are easily cured with antibiotics. We can prescribe and dispense treatment at the same appointment. For HIV, we will provide counselling and referrals for ongoing care.

Frequently Asked Questions

How soon after sex can I get tested for HIV?

Most reliable results are from 4 weeks after exposure using a 4th generation test. A negative result at 8 weeks is very reassuring. Our doctors will advise based on your specific situation.

Is the STD test anonymous?

Yes. We can test you using your first name only. No personal records are shared with third parties without your consent.

How much does an STD test cost in Koh Samui?

Prices depend on which tests you need. A single HIV rapid test starts from around 500 THB. A full sexual health screen is available at a package price. Contact us or see www.samuihomeclinic.com/medical-consultations for current pricing.

I have no symptoms. Should I still get tested?

Yes. Many STIs including HIV, chlamydia, and syphilis often have no symptoms in the early stages. Testing is the only way to know for certain.

Can I get tested and treated on the same day?

Yes, in most cases. For bacterial STIs confirmed by rapid test, we can prescribe and dispense treatment immediately.

Do you test for STIs other than HIV?

Yes. We offer a comprehensive sexual health panel including syphilis, chlamydia, gonorrhoea, hepatitis B and C, herpes, and more. Ask our doctor for a full screen.
