1. I HAVE LOW RISK : Get tested once a year
2. I HAVE HIGH RISK : Get tested every 3 months, and consider taking PrEP.

3. I MIGHT BE EXPOSED TO HIV : HIV screening is all about timing. The right test at the right time means accuracy.

- If your exposure was less than 3 days ago, see our doctor at the clinic ASAP to immediately discuss if you need emergency pill or PEP.

- If your exposure was 7-10 days ago, you should do the HIV RNA PCR. Results normally take 7 working days (for a surcharge of 3500THB).

- If your exposure was 14-16 days ago, you should do the HIV Combo test. Results normally take 1 working day (for a surcharge of 1200THB).

- If your exposure was 22-28 days ago, you should do the HIV Antibody test. This test can be easily done at the clinic, it takes 20 minutes and cost 500THB.


Also test for HIV if you develope symptoms of FEVER, MUSCLE ACHES, RASHES, SORE THROAT and ENLARGED LYMPH NODES. Note that these symptoms are not present in everyone with HIV so get tested if you think you are at risk.

Each day, more healthcare professionals are switching from reusable instruments to disposable, single-use ones. There are several reasons why this tendency is growing, and will continue to grow in the years to come. We are one of these leaders. We have been using disposable instruments from cotton, alcohol pad, single-used needles, gloves and we have been using these disposable products in all our branches in Thailand. If you reallized you concern too much about infection from getting tested at our clinics, do not worry about that we reassure you that what we use here are clean, we are here to protect and safe you from infections not to infect you with any possible infections!!! If you are worried unreasonably and you realize that seeking help from psychiatrist could be helpful, we can give you a list of recommended psychiatrist who will provide high quality non-judgmental non-stigmatizing service in private health care facilities.


If you have been at risk of HIV exposure then it is very likely that you have been exposed to other STDs. Because of this, we highly recommend that you also screen for other STDs such as Syphilis, Gonorrhea, Chlamydia, Hepatitis, Herpes and Warts.



The fastest way to find out if you have been infected with HIV or not is to do the HIV PCR TEST 7-10 days after the potential exposure.

The next earliest accurate test is the HIV Ag/Ab Combo test at 15-17 days post exposure. 

All other HIV tests are subject to a 3 months window period. In other words, you have to wait for 3 months before knowing for sure if you have been infected with HIV or not. In this time, you can potentially spread it to your sexual partners without even realizing it.

 If you took PEP before it is recommended that you consider taking PrEP after that for prevention.
