The best STI testing clinics in Bangkok should be compared by more than price or how quickly a test can be booked. Different clinics may offer HIV, syphilis, gonorrhoea, chlamydia, hepatitis or broader sexual-health panels, with important differences in sample type, window periods, confidentiality, doctor consultation and treatment if a result is positive. This guide compares providers in Bangkok that publish STI or sexual-health testing, helping residents, expats and travellers understand what each clinic offers before arranging a test.
Why these Bangkok STI testing clinics made our list
We compared the best STI testing clinics in Bangkok by looking at the infections each provider clearly tests for, whether medical consultation is available, how results are delivered, what information is published about confidentiality and follow-up, and whether treatment or referral is available after a positive result. We also considered practical details such as location, English-language support and whether the clinic explains the difference between individual tests and broader screening panels. The list below is intended to help readers compare options with more clarity before booking.
Pulse Clinic Bangkok (Silom)
Pulse Clinic publishes a dedicated STD testing page for its Silom location at 60/4 Silom Road, Suriyawong, a short walk from BTS Sala Daeng exit 3, stating that it screens for 28 infections by PCR panel with same-day results and describes its approach as confidential and non-judgemental. The site lists PEP among its related services and offers English-speaking staff across its network of Bangkok branches. It suits a reader who wants a private clinic embedded in the Silom neighbourhood with a walk-in lab option branded PULSExpress. Ask the clinic directly which panel and turnaround time applies to the specific infections you want tested, since panel size affects both price and result timing.
Bangkok Safe Clinic
Bangkok Safe Clinic operates from Room 314, Times Square Building, 246 Sukhumvit Road, a short walk from BTS Asoke, and publishes a HIV testing page stating that a rapid test returns a result within 20 to 30 minutes, while a laboratory blood test takes one to three business days, with the fourth generation test priced at 850 baht. The clinic states it is open daily from noon to 9pm, welcomes walk-ins alongside booked appointments, and describes results as protected under health data privacy law with a choice of email or paper delivery. It suits a reader who wants same-day rapid results without a prior appointment. Confirm current pricing for PrEP, PEP or any wider STI panel before you go, since the linked page covers HIV testing most closely.
Tangerine Community Health Clinic
Tangerine Community Health Clinic, run by the Institute of HIV Research and Innovation, publishes its address as Chamchuri Square Building, 11th floor, 319 Phayathai Road, Pathumwan, near MRT Sam Yan, and describes itself on its clinic page as Thailand's first trans-specific health clinic, led by trained transgender personnel. Published services include HIV and STI counselling, testing and treatment, PrEP and PEP, gender-affirming hormone treatment, neovagina care and hepatitis A, B and HPV vaccination. It suits a reader seeking trans-competent care delivered by staff who share that lived experience, alongside standard sexual health testing. The clinic states walk-ins are accepted during its Monday to Saturday hours, but registration closes two hours before closing, so confirm the current cut-off time before travelling.
be YOURSELF Unit, Bangkok Hospital
Bangkok Hospital runs its be YOURSELF unit for gay men's health from the 4th floor of Chiva Transitional Care at its Petchburi headquarters, 2 Soi Soonvijai 7, and publishes a gay men's health service page listing daily and on-demand PrEP, emergency PEP within 72 hours, HIV testing with pre and post-test counselling, and site-specific STI screening covering throat, rectal and urinary samples. The page describes its care as confidential, respectful and stigma-free. It suits a reader who wants sexual health folded into a full hospital campus rather than a standalone clinic. The published men's health check-up package sits well above the standalone clinics on this list, so weigh that against the hospital setting before booking.
MedConsult Clinic
MedConsult Clinic publishes a dedicated sexual health testing page from its Thonglor and Silom branches, listing HIV, syphilis, gonorrhoea and chlamydia tests alongside a 15 pathogen STI multiplex panel and hepatitis A, B and C screening, with published prices running from 260 baht for a single syphilis test to several thousand baht for the wider panels. The page states that walk-in service is available every day with no appointment needed, describes testing as anonymous, and adds that clients may use a pseudonym if they prefer. It suits English-speaking residents who want an itemised price list before they arrive. Turnaround varies by test, from one day for most panels to two or three days for the multiplex, so confirm timing for the specific test you need.
Rainbow Sky Association of Thailand - Ramkhamhaeng Clinic
Rainbow Sky Association of Thailand operates a clinic at Soi Ramkhamhaeng 97/2, Hua Mak, Bang Kapi, publishing on its services page that it offers PrEP and an HIV screening service through a booking link, with PEP and hormone testing published elsewhere on its site. RSAT states its mission centres on LGBTQIA+ communities and that most of its staff belong to the key population groups it serves. Published hours run Monday, Thursday and Friday from 1pm to 6pm and weekends from noon to 5pm, shorter than a standalone private clinic. It suits a reader who wants a community-led organisation with peer staff rather than a hospital setting. Confirm current opening days before visiting, since the published schedule covers only three weekdays.
SWING Silom Polyclinic
SWING Silom Polyclinic publishes its address as Room 607, 6th floor, 64 Silom Road, Suriyawong, and states on its clinic site that it offers HIV and STI testing alongside PrEP and PEP, describing consultations and testing as fully confidential and pricing as affordable, though it does not itemise specific fees. The site states it serves everyone inclusive of all genders, orientations and backgrounds, and publishes hours of Monday to Friday, 11am to 6pm, with weekends closed. Built around Bangkok's sex worker and LGBTQ+ community health tradition, it suits a reader who wants a clinic embedded in that history rather than a general private clinic. Because weekend hours are not offered, plan a weekday visit and confirm current pricing directly before attending.
PSK Clinic
PSK Clinic operates from the 4th floor of the Move Amaze building on Lat Phrao 19 Alley, Chatuchak, and publishes a clinic overview listing HIV testing and long-term care, syphilis, gonorrhoea and chlamydia screening, hepatitis A, B and C testing, HPV and herpes screening, and comprehensive packages starting at 1,800 baht. The site states that PrEP and PEP are available with prescription and follow-up care, that walk-ins are welcome alongside Line appointments, and that same-day rapid HIV testing is offered with standard laboratory results in one to three business days. It suits a reader who wants a choice between branded and generic medication, which the clinic states it offers. The page targets an English-speaking audience, but confirm which staff are on duty for your visit through its Line account.
OpenHouse Clinic
OpenHouse Clinic operates from the 6th floor of Park Silom, 1 Silom Road, close to both BTS Sala Daeng and MRT Silom, and publishes a STI clinic page naming two infectious disease specialists who assess which tests suit each visitor, with a fourth generation HIV test priced at 850 baht and STI panels between 1,700 and 2,500 baht. The page states that consultations are available in English, Japanese, Korean, Arabic and Spanish, and that PrEP and PEP assessments are offered alongside testing. It suits a reader who wants the testing decision made by a named doctor rather than a fixed package. Multilingual support is unusually broad here, so confirm in advance that your language is covered by the doctor rostered that day.
Things to confirm before booking an STI test in Bangkok
Before choosing an STI testing clinic in Bangkok, think about which infections and body sites actually need testing. A urine test alone may not detect infections acquired through oral or anal sex, and some infections require blood tests rather than swabs or urine. Ask what samples are used, whether throat or rectal testing is available when relevant, and how the clinic decides which tests fit your exposure rather than simply selling the largest panel.
Timing matters as well. Different infections have different window periods, so testing very soon after an exposure can produce a negative result that still needs repeating later. If you want broader guidance on sexual-health services in Thailand, this guide to STI testing in Thailand can help you understand common tests, timing and what to expect before choosing a clinic.
Finally, check what happens after the result. Ask how results are delivered, whether a doctor explains positive or unclear findings, what treatment is available, how partners are managed and whether repeat testing is recommended. A good clinic should make confidentiality, follow-up and next steps as clear as the test itself.
Thai Red Cross AIDS Research Centre operates the Anonymous Clinic at 104 Ratchadamri Road, Pathumwan, described on its own clinic services page as offering HIV detection testing, sexually transmitted infection screening and treatment, viral load and CD4 monitoring, and a transgender clinic. The page states that pre-exposure prophylaxis and post-exposure prophylaxis are both available, alongside a same-day antiretroviral therapy service for those who test positive. Opened in 1991 as the first anonymous HIV clinic in Asia, it suits a reader who wants a long-established public health centre rather than a private clinic. Confirm current walk-in hours and any fee for the after-hours specialist service directly with the centre before visiting.
