Anonymous HIV Testing at Our Clinic.

In 2008, we were given the mandate by the Ministry of Health to conduct anonymous HIV testing.

Registration form for Anonymous HIV Testing. No personal details required.

Registration form for Anonymous HIV Testing. No personal details required.

Not all clinics are allowed to conduct anonymous HIV tests. This is because according to the Infectious Diseases Act, all medical personnel are required to inform MOH of the details of any person they know or suspect of being infected with HIV. Our clinic signed a gazette that is filed with the Supreme Court of Singapore to excuse us from this section of the Infectious Diseases Act. We are therefore mandated under Singapore Law to be allowed to conduct Anonymous HIV tests. Yes, it is a big deal.

We use only Gold Standard HIV tests that are validated and approved according to the latest International Standards.

All Our Doctors are fully certified and trained in advance HIV testing.

We use only single use and disposable equipment and are validated by MOH for Good Infection Control Practices.

  1. Dr Tan,

    Thank you in advance for answering my quesion. I visited a CSW and engaged in Masturbation, I did not touch her and she did not touch me. After, I went to the restroom to clean up, I turned the faucet and washed my genitals using the sink water. My question is if there was vaginal fluid on the knob of the faucet could I infect myself. Thank you again for your time and help

  2. Hi Dr tan
    I have sex with a domestic helper at 18th Dec after three weeks 12th Jan i went to 11 unity clinic to do three step test, the result is negative.
    How accurate is the test result ?

    • You did not ask the doctor when you did the test?
      If you did a 4th generation combo test, result at 3 weeks is a good indicator. Best to repeat in on day 28 for conclusive result.

  3. Charles

    Dear Dr.Tan,

    I had made a Ag/Ab (CMIA) test after 6 months of sex exposure, the result is non-reactive, but I did not carried out the first test after 30 days of exposure when the Ag is highest,and I heard Dr.tan said that few peoples’body are unable to generate the Ab (antibody) even after 6 months and more. In this kind of scenario, may I know how could I conclude my result is non-reactive?

    Thank you.

    • In my opinion the combo test after 28 days is conclusive. However, we are not able to verify the accuracy of your results. For that you should refer to the doctor who did the test for you.

  4. Nicholas

    Hi Doc, I have went for sti screening back in Oct 16. My herpes II was at equivalent 1.1. But i am worried sick becoz there are red rash on the tip of penis every now and then. Not sure if it’s related to this herpes II. Please advise. Thank you

  5. Hi doctor,

    I have been engaging services from a few sexual workers over the past two month. I was practicing protected sex every time except unprotected oral sex for a few. I have been experiencing a headache for 1 week, 1 day mild fever and 2 days of diarrhea. My last exposure was 4 days ago. I am worried to death about contracting HIV and on which day would the test be conclusive if i were to get tested. Thank you

  6. Good Day Dr Tan,

    I had an occupational exposure 3 days ago when I pricked my finger on a lancet while taking blood from a patient of unknown status. While appropriate measures given by my superiors were taken, could you evaluate the risk of contracting HIV? Thank you.

    • The risk of contracting HIV from a percutaneous needle stick injury is 23 in 10,000. (Source: CDC HIV PEP Guidelines)

  7. Supreeth

    Hello Doctor, I am diagnosed with hsv 1 and hsv 2. Planning to get marry soon. Can I get married and lead normall sexual life? Should I be worried about herpes?


    • That is a very big question that should have been answered by the doctor who diagnosed you. We cannot possibly cover all aspects of HSV infection in a forum like this. As a quick summary I can say that many people with HSV lead very normal lives. For more details, please visit the doctor who diagnosed you with HSV.

  8. David Chan

    Doctor i have had protected sex last week and I would like to know the probability that i have contracted hiv even though i was using a condom and did not ejaculate

  9. Good Day Drs,

    At 4 weeks post exposure
    1) HSV1 IGB AB 0.08
    2) HSV 2 IGB AB 0.05.
    . I will be doing the 12 weekly as well.

    Are these results a little assuring.

  10. Doctor
    Where can i go for anonymous gnorrohea and chlamydia screening? If i am tested positive do i need to inform anyone?

    I also took hiv 1&2 rapid test at home twice after window period and both were negative. Does it confirm that i am negative for hiv? I dont really have symptoms. Just taking precaution because my ex-partner had an affair.

    • There is no such thing as anonymous gonorrhea and chlamydia screening in Singapore.

      I cannot comment on the accuracy of HIV home tests.

      • Hello doc ..I would to like to ask hiv ag/ab combo test is conclusive for 84 days or 90 days post exposure ?hoping for your reply thanks

        • In my view, the HIV Combo test is accurate after 28 days. However as we are not privy to the details of how the test was conducted, we cannot verify the accuracy of your tests. Please seek clarification from the doctor who did the test for you.

  11. completely devastated

    Dr’s…please please help. I had major aseptic meningitis, still with photophobia, that pinching headache that would cause momentary nausea, major aches in my arms and back , severe stiff back pain with liver pain that’s been on going for past 2 weeks after exposure. I had a few with night sweats soaking on my bed sheets for no apparent reason after coming back from Thailand with unprotected vaginal. Had 4th generation tests at 16 days and 19 days using Siemens hiv combo at the lab in austrlia. And a hiv Rna test at 19 days (roche cobas 20-10,000,000copies/ml machine, which I believe is the 2nd version? Since the 1st Gen. Has 48-10,000,000 detection level. With the on going liver pain, sensitive to lights, I feel they have missed the hiv strain such as a rare and crfs. What are the chances of these being correct? Do all strains have same p24 detection level? And would PCR RNA in australia be able to pick up the CRF strains? Since they would assume that most are subtype B in Australia? Please give me some insight as I am barely hanging…

    • I suggest you stop worrying about HIV and start worrying about what is actually causing your symptoms.

  12. hello drs,may i know 6 month hiv and hcv test are conclusive?do i need further testing?tq

    Dear Doctor,

    Good morning! I’ am Foreign worker and Masseuse provided me oral sex unprotected before 8 days. Now for last 2 days, am having urinary symptoms (penis whitish discharge,no pain). Based on your previous valuable comments, I suspect Gonorrhea or Chlamydia. So I want to do Comprehensive Men ANONYMOUS STD screening, in your clinic.

    Please advise if only screening is anonymous or the treatment too, is Anonymous?
    And if Confirmed Gonorrhea or Chlamydia, is there any problem for my EP/ renewal? Thank you.

  21. Hi Sir,

    I tested negative on week 6 on 4th generation test. But got symptoms like shoulderaches, joint pains and diarrhea after 2 weeks. My question is does the 4th gen finger prick test can it pick up hiv positive before the ARS or acute Hiv symptoms?

    • Yes. If you are concerned, you can perform an antibody test after 12 weeks.

      • Dear Dr,

        Thank you for your reply. I when for another test (4th Gen finger finger prick test & 4th Gen lab test) on week 8th after exposure. It is still negative. Do you consider this is reslut conclusive?

  22. lengleng

    good day to you sir,may i knw after six month hiv test negative,can i move on?

    • Generally speaking yes. But that depends on what test you did and whether or not the test was conducted properly. You should verify this with the doctor who did the test for you.

        Hi Doc Tan,

        Thank you for your reply… but I just want some answers…

        I have a risky exposure on july 8th protected sex but not for oral. I got a weird feeling on my penis next day. 3 days later, i have pain in my testicles and urethra. When to see a GP and took urine test for suspect gorronea or chamlydia. Both negative. On the 13th day, took a 4th generation finger prick blood test. Shown negative. Follow up on the 28th days, took a 3rd generation test and all sort of test like herpes, syphilis and all STD’s. Shown negative. And finally on the week 6th (42 days) retook a 4th generation finger prick test again and shown negative. 4 weeks ago i had pain under the chin. But it didn’t get swollen. And I have joint pains on my left knee and elbow till now. 2 days ago I had a cold sweat, plus this morning i wake up with diarrhea, felt like vomit and shoulder pain. Question is am I still hiv negative? Like i mention my last 4th generation finger prick test on week 6th is negative.



  25. Robert A

    Hi Doctor,

    On the 8th or 9th July I had sex with a Cambodia sex worker. Using protected from sex but not for oral. (Anyway she bit my nipple and it had a small wound) A week later i had pain in my urethra and testicles. When for all sort of test (STD, HERPES AND HIV 3rd generation test) on the 28 days. All turn out negative.i had pain under my chin felt like inside the veins. But it doesn’t feel like swollen lymph nodes. Plus my left knee there are joint pains. On the week 6th (42 days) i when for a 4th generation test and it turn out negative. The pain under my chin just wont go off. What are the risk I am having? Do I need to go for another retest? Even my GP told me I don’t need to come back.Is my pain under the chin and knee due to stress?

  26. Hi doctor, I understand that surfaces such as door handles cannot transmit hiv. But in my situation, I got a fingerprick test, and then I proceeded to opening a door knob with the same pricked finger. What if there’s HIV on the door knob? Can it enter my finger prick hole? Or am I worrying for nothing? God bless you.

  27. Is HIV antibodies test give false negative Elisa test after 2.5 years from unprotected sex with a women who is HIV test negative at the same time with me.please I suffer symptoms from a lot .am I rule out HIV infection at this stage doctor

  28. david112

    hi doc, im just curious about my symptomps since i paid for sex around 5-6 weeks ago before catching a fever. I did protected sex that last for about 2-3 min and oral unprotected like 1 minute.

    fever lasted only 2-3 days, like a flu (i forgot to take temperature) and with quite a heavy headache , runny nose, cough and fatigue. there are no rashes and i didnt sees enlarged lymph node.

    im kind of paranoid reading the comments and tried not to be based on self diagnosys.

    and now im freaked out for every minor sickness like mouth ulcer that happened like every month or so.

    your advice would be much appreciated thank you

    • My advice is go get HIV and STD tests done and get this out of your head. The problem is simple: you are worried if you have been infected with HIV/STDs or not. The solution is just as simple: get tested. Worrying is not going to solve your problem. Analyzing your risk is not going to solve your problem either.

  29. hello Dr, typhoid fever affected me and I go to clinic, the doctor told me that my white blood cells is very low, he didn’t give me further explanation, what it shows? is typhoid affect white blood cells?

    • There are many possible causes of lymphopaenia. I suggest you take this question up with your doctor.

  30. Hi doctor
    I had sex with a domestic helper last year may when she is on her period. Went for a health screening with hiv test included. Test is negative. How accurate is the test results if I had blood drawn on a Friday ? Will It affect antibody test blood when left over the weekend ?
    I have had rashes ever since the last encounter and its recurring
    Is my test results conclusive ?


    • That is such a strange question. First of all, how sure are you that the blood was left over the weekend? Here in Singapore, HIV tests are run everyday at private labs. Even on the weekends. Anyway, even if it was left over the weekend, that would not affect the accuracy. What will affect the accuracy is when you did your test after the encounter (window period) and the type of HIV test done. Since it has been more than a year from your exposure, I don’t see any reason to doubt the accuracy of your test. You should also see a doctor about your rash and not assume it is due to HIV.
