False Positive? Please, I need Resolution...

Please, I need your take on my situation;

Around 6 months ago a have unprotected sex with a girl of unknown HIV status (one night stand). I did a routine health check and this results came out;

1)Last Unprotected sexual exposure Sept 9, 2014

2)Routine Screening HIV test ; Oct 7, 2014 (28 days) – ICMA Test Repeatedly Reactive 1.45: then, HIV 1/2 Differentiation Test (HIV 1 Non-Reactive and HIV 2 Non-Reactive): The results were giving to me via phone since I was out of the USA at that time. The lab recommendation was for me to get an RNA test on a new specimen. Since I was out of the country I couldn’t find a place to do it, so I went to a private Lab in the country I was and they performed the following test;

3)Oct 15, 2014 (36 days): COBAS E-411 ECLIA: NEGATIVE (they performed the test twice with the same blood sample just to make sure). The Lady at the lab told me that this was a 4th Generation Test, but I don’t have a way to confirmed since the results document only says “HIV COBAS E-411 ECLIA: NEGATIVE”

Then, back in the USA, I performed the following HIV tests;
4)Dec 09, 2014 (98 days): I went again and did the same original Lab: HIV 1/O/2 Abs-ICMA; Non-Reactive
5)Dec 09, 2014 (98 days): With the Same blood Sample above I requested a 4th Generation HIV test: Non-Reactive
6)Feb 03, 2015 (160 days): I request a RT PCR RNA Test and the result was Negative <20copies/ml
7)Feb 24, 2015 (180 days): I went and bought an In Home Oraquick HIV Test and was Negative (only a C line visible)
8)Mar 01, 2015 (188 days): I went and bought another In Home Oraquick HIV Test and was Negative (only a C line visible)


My questions are the following;

1)Does my first test was a false positive?
2)Can I trust my later Negative Results?
3)I have being having painful lymph nodes under my neck, arms and one leg and weird sensations all over my body.
4)Do I need more tests?
5)What should I do?

Thanks for your time.

Thanks for the information Vince. Its just very difficult to get over a false positive test, even after having multiple negative tests after the first false positive. And then with having multiple symptoms (mouth ulcers, swollen lymph nodes, and others). My last question was about the validity of the RT-PCR-RNA test at 160 days (<20 copies/ml). Mine was negative at 160 days. Thanks

Hello Vance.

Vance, can I get the answer to my last question?

What is your opinion on the RT PCR RNA Test at 160 days (<20 copies)? Do you think someone infected and without treatment could have this result at 160 days post exposure?

Thanks.

Vance, sorry I keep asking questions all over again. Could you answer this?

1) Can the PCR RT RNA (<20 copies) test be false NEGATIVE at 160 days after exposure?

2) Can you get a flase NEGATIVE on the ICMA test at 98 days or 10 weeks after the first positive ICMA test?

3) Do you know if the ECLIA COBAS e-411 Test is a 4th or 3rd Gen Test?

4) Can I trust the Oraquick home tests?

5) I forgot to mention that I did another Oraquick (9 days after the last one or 6 months after exposure) and it was negative (only a line on the C).  

Thanks

It was a false positive, simple as that. You have 5 negative test after the window period, you don't have HIV.

Vance, Thanks for answering, I really appreciated.

What is your take on the first test? The ICMA was Repeatedly Reactive with a value of 1.45: but then, the HIV 1/2 Differentiation Test (HIV 1 Non-Reactive and HIV 2 Non-Reactive):  

Why this happened?

Can I trust the Oraquick tests and the RNA?

Thanks
