Oraquick test at 4 months conclusive?

Oraquick test at 4 months conclusive?

Not entirely: If positive it needs to be confirmed. If negative, you should repeat it as some people take up to a year to make enough antibodies for a positive result. If you wish to make sure, ask your doctor for an HIV nucleic acid test which would be conclusive at 4 months after exposure. ...Read more

Negative 4 gen HIV including PCR and 8 STDs at 29 days. Later at 5 months same test,negative. Negative HIV antibody at 7 months. All conclusive?

Negative 4 gen HIV including PCR and 8 STDs at 29 days. Later at 5 months same test,negative. Negative HIV antibody at 7 months. All conclusive?

Yes, conclusive: The 4th gen HIV tests are conclusive any time 4 weeks or more after the last exposure, so your first test was conclusive for HIV; the other HIV tests were superfluous. Depending on which STDs were tested, some of those were conclusive at 4 weeks, and the others probably conclusive at 5 months. You can stop testing for HIV and any STDs based on an exposure 7 months ago. Best wishes. ...Read more

Is a RNA HIV test conclusive at 7 weeks from high risk exposure or retest at 12 weeks?

Is a RNA HIV test conclusive at 7 weeks from high risk exposure or retest at 12 weeks?

Retest: I think that today's tests are conclusive at 7 weeks. However, you're also young, you did something risky, and you're going to be anxious unless you retest at 12 weeks. Do it -- not for the science, but for your own peace of mind. And whatever happened, I hope you've got a memory you can both learn from and also cherish -- you gave and received affection. Be safe from now on. Cheers. ...Read more

Is Negative HIV RNA and 4th Gen Ab/Ag conclusive after 34 days post exposure?

Is Negative HIV RNA and 4th Gen Ab/Ag conclusive after 34 days post exposure?

Yes conclusive: By itself, the 4th generation blood test is 100% conclusive any time 4 weeks or more after the last possible exposure. The negative RNA test wasn't necessary unless you had a particularly high risk exposure, but it confirms you don't have HIV. Assuming you haven't had post exposure prophylaxis (PEP), which if unsuccessful can delay positive testing, you don't need any further tests. ...Read more

Handjob at massage parlor. tested for HIV with 4th gen test at 4 and 6 weeks both neg. Also had a negative HIV RNA at 20 days. Are these conclusive?

HIV: HIV is transmissible through body fluids. Unless you had an open sore on your penis and the massager who gave you the "hand job" had an open sore, that were in contact, there is minimal to almost no chance you contracted hiv from that encounter. The tests are good, but remember any HIV exposure can take several weeks to seroconvert to a positive blood test. ...Read more

I had a hiv ag ab combo 4th gen test done at 3 weeks 6 weeks and 19 weeks are they conclusive still very scared?

4th gen HIV tests...: ...are 100% conclusive any time 4 weeks or more after exposure. There is no basis for continuing to be frightened you have HIV. Assuming you haven't been reexposed more recently, your 6 week result was conclusive and your 19 week test unnecessary. Stop testing and do your best to move on without worry. Also test for gonorrhea, chlamydia, and syphilis if not done, much higher risk than HIV. ...Read more

Hiv rna test result undetected after unprotected blowjob at day17. Test range 40 to 10mil. Is it conclusive?regular hiv test neg at 15 days. Hiv?

No risk: HIV is rarely transmitted by oral sex. If you were the receiver of the BJ, you can be sure you weren't infected: there are few if any proved cases of oral to genital HIV transmission. Most experts would have recommended against an RNA test in this situation, but the negative result is additional strong evidence you weren't infected. The "regular" test is only slightly reassuring, 4-6 wk minimum. ...Read more

I just had polymerase chain reaction (pcr) HIV test negative at 4 weeks 6 days, almost 5 weeks?

Probably free: There are rare cases in which antibody testing has remained negative for several months, but you probably do not have hiv. If you are in a state of anxiety over this and can afford it, a PCR for the presence of viral RNA in your blood will solve this definitively. ...Read more
