  1. will hiv be transmitted through hair cut as in your article it said hiv can survive up to 7 days in normal environment.

    • I have not heard of HIV being transmitted via a visit to the barber although I get a lot of enquiries on this. I do not know who started this urban myth. If you think your situation truly has put you at risk of HIV, please go speak to your doctor.

  2. i had a protected sex but after we have finish successfully. she play with my dick am so curious to have the virus…. according what i heard must of the people who have the virus always want pass it on to others…
    what of if she intentionally touched her private part and put the semen on my panis?
    am i at risk of contacting the virus?

    • You are at risk from the protected sex, not from her fondling your privates. The simple, but not often recognized fact is that condoms are very good in protecting one against HIV but it is not 100% effective.

  3. Protected vaginal sex with a worker… made unprotecded blowjob… sucked my penis… 21 dayss later, I have the flu…My swollen lymph… 8 week (60 day)- 4 my generation hiv test negative… Antigen-0.1 antibody-0.6 (Vidas Hiv duo ultra)… I am Hashimoto… My test result is reliable ??? Should repeat the test ???

    • The HIV 4th Gen test at 21 days is extremely accurate. In my view as good as conclusive. However, according to guidelines, you still have to repeat the test at 1 month post exposure. Your exposure was also extremely low risk. I do not see any reason for you to be worried.

  4. Dear Doctor,

    I wish to check the risks on having a naked body massage. Am I at risk of HIV/STD? Do i need to get a check up done? I am unsure if I may have been in contact with any body fluids from the lady, no form of penetration was present.


  5. Hello doctor tan just wanted to ask

    If my blood draw sample for HIV combo test is exposed to the air would that make my HIV test inaccurate ? If not then why ?

    I have heard HIV dies once outside the body so will that effect my test results ?

    How long can blood sample be exposed to air that can cause HIV test to be in Accurate ? Thanks for the reply .

  6. Hey Dr.
    I had a hiv antigen w/hiv 1&2 ABS test approximately 7 weeks and 4 days after exposure (53) days and it came back negative.
    How conclusive is this test result?
    And how conclusive is it in your opinion?

    Thanks for the answer in advance…
    Thanks again

  7. Hi Dr,

    Just want to check my risk of contracting HIV/STD.
    I recently had a full naked massage with the lady massaging me and giving me a masturbation through out. I am unsure if her vagina had touched my penis or were there any exchange of body fluids. Should I be worried and get a test?

    This occured on 11 Nov 2016.

    • There are STDs that can be transmitted via skin to skin contact. Please see your doctor for more advice on the need for screening.

  8. Hello Doc .

    Just want to check that does HIV virus died when exposed to air ?

    Because, the toilet seats in the public stained with dried blood and i accidentally sit on (omg) and i wasn’t sure if the previous user is a HIV + . So, my question is .. what is the risk of me getting infected ? 🙁

    is there high chance i will get ? Please advise.

    Thank you!

  9. Hello dear doctor!

  10.

    2. Is the Combo Duo Test also test HIV2 or HIV1 Only ?
    3. should I Test Again after 3 months ?
    4. was my test conclusive and 100% no HIV ?
    5. If I want test HIV2, what metode available and when ?

    Thank You Doctor for your answer

    • 1. It will also cover the previous exposures.
      2. Depends on what test you did. Ask your doctor.
      3. Ask your doctor.
      4. Ask your doctor.
      5. There are tests available for HIV2. Ask your doctor.

  11. Dear Doctor, if I have test HIV Combo after 5 weeks is Non Reactive, is it conlusive and valid ?? Should I test again in 3 months ? Thank you

    • In my opinion it is conclusive. Please see the doctor who did the test for you to verify the accuracy of the test.

    Hello Doctor,i recently have a 2nd dose of HBV vaccinations, can this vaccination causes a incorrect blood test result in any STD testing (HIV, Herpes,Sypihilis etc)

  13. Does fingering with hangnail wound posses HIV transmission risk?
    I didn’t insert the finger into the vagina it was only superficial but the finger with hangnail wound may have touched the opening of vagina and if any secretion may have come into contact with the finger.

    Is there any risk of HIV transmission given I don’t know the HIV status of the girl?

  14. Helo doc. i want to ask before i had unprotected sex with a girl at 04 Oct 2016. She told me she didnt have it. She already go check in Thailand also. After do that i got sick like fever, sore throat, hard to shallow, fatique, the eyes looks so brightness, sometimes headache.
    I got test after 10days with elisa test the result is negative. and she also get the test at 15 days after that. the same result negative. Should i test again 30 days or 90 days? how about my body problem?

    • No HIV test on day 10 or day 15 is conclusive. If you are worried about HIV, do a HIV combo test on day 28 to be sure. Your symptoms are consistent with pharyngitis or tonsillitis. See a doctor to get yourself assessed and treated.

  15. Hai Doc, i have a masseur gv me a hanjob and he wipe my semen with a towl. am i in a risk of contracting HIV
