Confidential STD and HIV Testing in River Valley
Atlas Pacific Medical is a GP clinic at 428 River Valley Road (#01-10 Loft@Nathan, Singapore 248327) that offers confidential STD and HIV testing. You can walk in or book a same-day appointment. A doctor sees you in a private consultation, recommends the tests that fit your situation, and explains your results once they are ready. We test for the common sexually transmitted infections, including chlamydia, gonorrhoea, syphilis, herpes, HPV (human papilloma virus), trichomonas, mycoplasma and HIV, and our doctors treat many of them at the clinic. The clinic is near Valley Point Shopping Centre and about 9 minutes’ walk (670 m) from Great World MRT (TE15), Exit 4. We are open Monday to Friday and on Sunday evenings, with evening hours until 7:30pm from Monday to Thursday (on Friday we are open until 4:30pm). Testing here is confidential: your results stay in your medical record and are not shared with your employer or insurer without your consent.

Frequently asked questions
Do I need an appointment for an STD test?
No. You can walk in during opening hours, or book a same-day appointment by phone or WhatsApp if you’d like a set time.
Is STD testing at this clinic anonymous?
Testing here is confidential. Your details are recorded, as at any GP clinic, and your results stay private within your medical record. There is no anonymous programme for STD/STI testing in Singapore. Only HIV can be tested anonymously at a limited number of approved clinics. Read more about anonymous vs confidential testing.
Do you treat STDs at the clinic?
Our doctors treat most if not all STIs at the clinic, including but not limited to common infections such as chlamydia, gonorrhoea, herpes, mycoplasma, ureaplasma and syphilis. Most infections can be managed quickly with antibiotics or similar treatment. For syphilis, first-line treatment is an antibiotic injection, followed by blood tests every 3 months to check it has cleared.
Which tests should I do if I have no symptoms?
Many STIs cause no symptoms, so screening is worth doing if you have a new partner or unprotected sex with a casual partner. The doctor will suggest a panel of tests based on your history. See our STD testing options and packages.
