Is HIV RNA PCR Test Done 29 Days Post Exposure Conclusive?

Posted on Thu, 23 Feb 2017

Question: Hello I had unprotected sex with a female on January 3rd. I tested Positive on The 4th Generation Elisa Test on XXXXXXX 11th 8 days after my exposure. My PCR RNA test was on XXXXXXX 16th 13 days Post exposure and it was Negative. I also went to another clinic and again Elisa tested positive on January 17th 14 days Post exposure. The PCR RNA test at that clinic was on January 18th 15 days post exposure and again I tested negative. I am still scared but my doctor assures me that I do not have HIV. Can you help put my fears to rest. Also the 1st ELISA test 8 days post exposure seems too early to detect anything but a False Positive thoughts?

Thank you.

Is anyone working on my question. Fo I have HIV is PCR RNA more reliable then EISA test 8 and 15 days post exposure. Also I was born with Hepatitis B could this have impacted the results

The test that I tested positive is the test uour telking me to retake?? The resukt will be the same most likely Reactive? What then take another PCR RNA?

I want to do a PCR RNA at 29 days if negative is it accurate that I am negative? I am seeing Infectious Diseases specialist on Feb 2nd. I am terrified i have HIV. My only hope is two negative PCR RNA tests

Online it daid that PCR RNA is 99.6% accurate after 14 days? So its not reliable more then 90% in the USA it is to gold standard correct?

Answered by Dr. Sunil Jangid (6 hours later)

Brief Answer:
Nothing like that.

Detailed Answer:
Dear XXXX,

It is not like that RNA PCR is unreliable but after 15 days or one month reliability is 90% and after more than 6 weeks it is 95-99% so don't take it as wrong because the test is definitely reliable and accurate.

It is absolutely fine.

Dear XXXX,

The chances of ELISA being false positive are high during first two weeks so no need to get bothered from it and if you want to go for RNA PCR then it is absolutely fine so be relaxed and go ahead for it.
