I had unprotected oral sex  on me I saw no blood I have no sores I am circumsized I have tooken a HIV dna pcr test at 18 days and a 46 also a 4 week and 6 week duo test and a 8 week rapid test am I ok?

You're OK: Oral sex is safe sex for HIV, with no proved transmissions by fellatio from mouth to penis, only rare ones penis to oral. You didn't need testing on account of this event and for sure not the multiple expensive ones you had. But the results from that combination of tests are conclusive. For sure you didn't catch HIV during that exposure and no further testing is needed. Best wishes and stay safe! ...Read more

Polymerase Chain Reaction (Definition)

Polymerase chain reaction is a method of finding a specific piece of dna and copying it over and over again until there is enough to study. The technique allows a scientist to detect very small amounts of dna in a swab sample then reproduce enough of it to study it. It is very sensisitive for detecting the presence of certain bacteria and is also used in doing other ...Read more

Is HIV PCR DNA test after 9 weeks conclusive enough?

Is HIV PCR DNA test after 9 weeks conclusive enough?

HIV PCR testing: Yes. This excellent new way of testing viruses is very sensitive. It is thought that the HIV pcr dna test can narrow the window to 14 to 21 days post exposure. A negative test at 9 weeks post exposure means you do not have hiv. ...Read more

Too soon: Not reliable at all. I am shocked anyone would even offer you such a test before the test could possibly be valid! the HIV pcr test can be accurate after fourteen days. Most of us wait till day 21 after exposure to erase all doubts. You tested too soon! ...Read more

Should I go for chemiluminescence immunoassay test after testing negative for DNA PCR for HIV1&2 after 90 days?

No: You should be thankful for good health. You should be thankful that you gave and received love, however imperfect it may have been -- human love always is. You should be proud to be a man. You should embrace life and love responsibly. And unless Dad is a total fool, maybe you and he can have another good talk. ...Read more

What reasons would cause an HIV dna/pcr test to be "false negative". Does waiting too long to test using it effect the result?

What reasons would cause an HIV dna/pcr test to be "false negative". Does waiting too long to test using it effect the result?

False Negative: A false negative means that a test result said a condition was not present when it was, thus the negative result is false. Please let your doc determine what is false negative or false positive. Peace and good health. ...Read more

Why is the HIV DNA PCR test not recommended after 4 weeks of exposure? Would it still be a good measure if used past a 3 month time frame?

Why is the HIV DNA PCR test not recommended after 4 weeks of exposure? Would it still be a good measure if used past a 3 month time frame?

HIV RNA PCR: It is completely diagnostic at four weeks. Who told you otherwise? But it must be combined with one of the newer generation antibody tests in case you happen to have a natural ability to suppress the viral replication. ...Read more

I had an HBV DNA PCR test and it came out to be 13 iu/ml...Is it a matter of tension? My lft and other tests come out to be positive although

I had an HBV DNA PCR test and it came out to be 13 iu/ml...Is it a matter of tension?  My lft and other tests come out to be positive although

Hepatitis B: Having a positive hbv dna and "other tests positive" in general means you have hepatitis b. This is not do to tension. Without knowing the specifics of your other blood tests and overall condition, i would see your liver specialist to see if you need treatment or if you can just have your liver tests checked every few months. ...Read more

1 month after HIV exposure, I had a PCR DNA, it was negative. 8 months later I used Oraquick Home and it was negative. Are my results conclusive?

1 month after HIV exposure, I had a PCR DNA, it was negative. 8 months later I used Oraquick Home and it was negative. Are my results conclusive?

Yes: ELISA or enzyme linked immunoassay for detection of antibody against HIV has a window between 30 days and up to six but after initial HIV exposure. Western blot it's a confirmatory test if the initial ELISA test is positive. However, rapid qualitative immunoassay for antibody against HIV virus alone is not indicative of negative HIV test since The virus can be dormant for several months. ...Read more
