Where can I do an STD test in Singapore?

Not all clinics in Singapore are allowed to conduct anonymouse STD testing.
The below clinics provide STDs and HIV testing anonymousely. 

• Dtap Clinic 
• Tanjong Pagar Medical Clinic 
• Kensington Family + Clinic 

Also, there are some test kits that you can do at home.
