STD Test Packages and Prices in Koh Samui
Three clear packages, no hidden fees. Not sure which one fits? WhatsApp our doctor, tell us what happened and when, and we will recommend the right test for your situation rather than the most expensive one.
Prices in Thai baht. All costs are confirmed with you before any sample is taken. Individual tests for a single infection are also available: WhatsApp +66 95 073 5550 and tell us what you need.
Which STD Test Package Do You Need?
The right package depends on what kind of contact you had, how long ago it was, and whether you have symptoms. As a general guide:
- Essential (2,500 THB) suits a routine checkup, a new relationship, or anyone who has never been tested. It covers the four major blood-borne infections: HIV, syphilis, hepatitis B and hepatitis C.
- Standard (3,500 THB) is the right choice for most people after unprotected sex or a condom break. It adds urine tests for gonorrhea and chlamydia, the two most common bacterial STDs, which often cause no symptoms at all.
- Full PCR (8,000 THB) is for multiple partners, ongoing symptoms, or when you want the most complete answer. The 15-pathogen PCR screens for a much wider range of infections than a standard panel, including ones that routine tests often miss. Read more about why PCR STI testing picks up what standard tests miss.
If you had oral or anal sex, tell the doctor. A urine test does not detect infections in the throat or rectum, and throat gonorrhea is one of the most commonly missed STDs. The doctor can add a site-specific swab if needed.
STD Window Periods: When to Get Tested
Every infection has a window period, the time between exposure and when a test can reliably detect it. Testing too early can give a false negative. The figures below are general guides; the doctor confirms the right timing for your exposure at your consultation.
| Infection | Sample | Reliable from |
|---|---|---|
| Chlamydia | Urine | 1 to 2 weeks after exposure |
| Gonorrhea | Urine (swab for throat or rectum) | 1 to 2 weeks after exposure |
| Syphilis | Blood | 3 to 6 weeks, recheck at 12 weeks after high-risk contact |
| HIV (antibody test) | Blood | From about 4 weeks, conclusive at 12 weeks |
| Hepatitis B | Blood | Usually within several weeks |
| Hepatitis C | Blood | 8 to 11 weeks |
| 15-pathogen PCR | Urine or swab | Most targets from 1 to 3 weeks |
Testing early still has value as a baseline, and many people test now and again later. For a full breakdown by infection, see our guide to STD test window periods.

Do You Need Symptoms to Get Tested?
No. Most STDs cause no symptoms at all, especially chlamydia, gonorrhea and early HIV, which is exactly why testing matters. Read more about STDs with no symptoms. If you do notice any of the following, get tested and tell the doctor:
- Unusual discharge from the penis or vagina
- Burning or pain when passing urine
- Sores, blisters, lumps or a rash around the genitals, anus or mouth
- Itching or irritation in the genital area
- Pelvic or lower abdominal pain
- Bleeding between periods or after sex
- Flu-like illness two to four weeks after a risky exposure
Seek care promptly if you have severe pelvic or abdominal pain with fever, or painful sores that are spreading.
Positive Result? Treatment on the Same Visit
A positive result is not a reason to panic. Most STDs are very treatable and many are completely curable. The doctor explains exactly what your result means and, where appropriate, starts treatment the same day, such as antibiotics for bacterial infections or antiviral medication for herpes.
We also advise on informing partners, when to retest to confirm the infection has cleared, and can provide a medical letter for follow-up care back home. Learn more about chlamydia treatment, gonorrhea treatment, syphilis treatment and herpes treatment in Koh Samui.
