HIV infection and testing requirements

User Profile
Dear Sir,

I am 36 yrs old male,I met with a prostitute on Aug 22nd'2009 and I was involved in oral sex for very short while with her and no other means of sex, when she put my penis in her mouth,I removed it immediately suspecting she may be HIV positive, it was just a matter of just 4-5 sec that's all and I have left her place after that.

After 72 hrs I got myself tested with the advice of a doctor.The test is "HIV PCR DNA QUALITATIVE". The result of the test is NEGATIVE.

Now I would like to know,am I completely out of the risk of getting HIV ?

Should I get myself tested again ? If yes which is the TEST and WHEN I should get TESTED ?

Please help me , I am still very frightened about this.

With Regards,

Rajesh

HIV and AIDS Answer A7207


Given the data you provided (having extremely short contact, being tested after 72 hours, results are “HIV PCR DNA QUALITATIVE”), it seems likely that you have very low chances of being infected. HIV transmission might occur when blood or semen from an already infected person comes in contact with the blood of another person.


Even small sores in the mucosa (oral, penile, vaginal, or anal) might be enough for the HIV virus to enter the body. Usually it takes a little more time than several seconds of contact accompanied with blood or semen transmission for infection to occur.


The HIV PCR DNA qualitative test detects the presence or absence of HIV. It does not count or calculate the number of viral particles in the blood. The time period of only 72 hours after the contact might not be enough for the test to be accurate.


You might want to ask your doctor about how long it takes for the test to be accurate. This particular data depends on the brand and is usually given by the manufacturer, which was not reported in the question.


If you were tested too soon, you might want to wait for the right time. Also, testing with HIV antibody tests (ELISA, Western blot) three months after the intercourse might be enough for definitely confirming or ruling out the HIV infection.


You might want to visit a specialist for infective diseases and consult about the HIV diagnostic options.
