4th Generation/DUO test

Accuracy of Point of Care HIV Test

Hey guys,

I would like to start with the thing that I am on PreP and taking it every day. 3 weeks ago or maybe a bit less I had unprotected sex and starting from Saturday (4th day today) I've been having a severe headache that never had before and some fever not higher though than 37.8C.
I am on painkillers right now and I would say it works quite alright. I tested my blood for HIV by HIV DUO Quick HIV1/HIV2 BIOMERIEUX yesterday and got results to be negative today. I asked the consultant about my situation taking into consideration the fever and severe headache whether it's confirmed that these symptoms were not caused by the conversion just by smth else since I believe that if someone has a conversion going on in their bodies with above-mentioned symptoms it means that a viral load is high and it would be easily detected by the machine. The consultant asked me to contact my doctor since he was not sure about that. I am out of the country now and I've got no possibility to do so. Could you please help me with that?
P.S. I stopped taking PreP on Saturday, the day I felt bad.

4th Generation test at 6 weeks reliability

Hi and thank you for the great service!!
I recently had a possible HIV exposure. While in Amsterdam I had vaginal intercourse with a window sex worker. A condom was used but I did not check its integrity by the end of the of the encounter which has significantly raised my anxiety level to the max. I had a fourth generation test done in amsterdam 4 weeks after the possible exposure and then again at 6 weeks, both came back negative! I also had an Insti rapid HIV test done at 45 days which also came back negative. My question is my situation looking ok? What are the odds of me getting a false negative out of these three tests? and finally do I need further testing?
(The nurses present at these tests all gave me different answers about the conclusiveness of these tests which is why I'm super confused)

HIV retest necessity?


I had exposure (mutual masturbation and titsex) with a sex worker two years ago. No oral, vaginal or anal sex took place. Oil was used on my penis and her breasts for lubricating. Half a year later I received a HIV screening (4th gen) along with my physical, which came back non-reactive. Should I retest due to possibility of false negative?

4th Generation EIA "DUO" Test, Conclusive?

Hello Doctor, I am sincerely hoping you can give me a sense of relief because the past 2 months have been a complete NIGHTMARE for me. Let me start by giving you the full story. On May 5 I had unprotected oral sex with a guy that lasted for about 2- 3 minutes. he did not ejaculate but I am unsure ofthe pre-semen. He then penetrated me unprotected for about 1-2 minutes in which I stopped him and made him put on a condom. After we were done, he removed the condom and cleaned himself up he and then penetrated me again for about 1-2 minutes.Which I again stopped him because he did not have on a condom. I am unsure if any semen or pre-semen entered my body which has me going nuts! about 3 weeks later I had diarrhea. I am lactose intolerant so I sort of thought it could be from that so I did not worry about it. On June 4th The day before my birthday, I noticed I had a sore throat and dry cough with a very low temp. I immediately scheduled a visit with my doctor as I was really nervous. I had a slight fever and asked my doctor to perform an STD test. When I got my results back I tested Syphilis - Negative HEP B - Negative Hep C = Negative HIV = Negative HSV 1 Negative HSV 2 Positive Although I tested positive for HSV 2, I thought I was okay as for the HIV results, however, I read that there was a window period and I would need to retest. As time went on I started to have a very upset stomach gassy bloated and diarrhea. It went away for awhile but occasionally comes back. I went to the dentist because of infected wisdom tooth and they prescribed me Clindamycin which I developed thrush and more diarrhea I was told that this was possibly due to the meds. I also have had dry mouth which I also heard could be from the meds as well. My Period for this month is noticeably lighter than normal which I am freaking out about. I never got a rash or anything or that I have noticed. About a week ago my husband (Yes I am married which I feel HORRIBLE About)started having diarrhea with an upset stomach. I noticed a rash on his knee which looked more like a bruise than a rash it was red and purple with no bumps and very small. He works as a contractor and is always on his knees so he could be from that and his hands are dry which made me worry as well, but he has had no other symptoms. I also noticed that I had a small swollen parotid lymph node (Or so I think)which has since become very very small, almost unnoticeable. I got nervous and decided to go back to the doctor so that she could test for HIV again. The results were still negative. My mouth is dry not and in my opinion not producing any saliva which is a major concern for me. I continuously chew gum to remedy this. I am on Klonopin to help with my anxiety. I have taken many tests to try and ease my mind but I am still unsure. Here is a clear timeline of each test EXPOSURE DATE- May 5 June 6th Lab-4th generation Duo Test Results = Negative June 23rd Lab-4th generation Duo Test Results = Negative June 29th Oraquick Home test Results = Negative July 9th Oraquick Home test Results = Negative July 12th Lab-4th generation Duo Results = Negative Husband took a test as well July 2nd Lab-4th generation Duo Results = Negative The other guy took a test as well July 1st Oraquick Home test Results = Negative, however, I wasn't the when he took it so I dont know the accuracy. less than br/ greater than Doctor, I am truly a nervous wreck at this point because I have been feeling very tired lately as well. Which could be due to the Klonopin but this just as on to my feelings of Anxiety. Can you please please please post and respond??? Sincerely Extreme Panic Attack

4th Generation EIA vs. HIV Home-test


I took bought an online hiv test to take at home and it came back "reactive" 5 weeks after I slept with someone.

The online company told me to go to my nearest STI clinic to take anther test. The STI clinic gave me the 4th generation ag/ab test six weeks after exposure which came back negative. I was then told to come back 4 weeks later to retake the test, I done this and it came back negative again. The 2nd time I took the 4th generation test would make it 10 weeks after I slept with that person.

Would you say I am HIV negative and I should stop worrying? I still feel worried and I feel like i have symptoms but Im not sure if it's the stress of worrying that may be causing them.

Also would you be able to tell me what can cause a false positive result to happen? I spoke to the online company that I first took the test with and they said that false positives are always a risk when taking the test.

Many Thanks

Can Antibiotics Alter the Results of 4th Generation Test


Does a surgery and follow up medication could alter the result of a HIV 4th generation in any way.?

Conclusiveness of 4th Generation HIV Test

Good morning,

I appreciate all the information I have received in this website.

I am from Ontario, and I recently received a 4th generation HIV test at 61 days (8.7 weeks) in one of the public sexual clinics.

My exposure was unprotected oral (giving and revieving) and protected vaginal with a sex worker. I did ask her about her HIV status and she said she doesn’t have it, and that she gets tested every 3 months.

I was wondering how conclusive is my test? I see websites like CATIE that state 99% of positive HIV carriers are found in 1.5 months with the 4th generation test, and countries like the UK, Sweden, and Germany have the 6 week period as an official guideline for low risk exposures.

I am concerned since I had high fevers on the 4th day, 23th day, and 39th day after exposure. I was diagnosed with 2 strep throats and mono. I do know if I seroncoverted during these instances my HIV test at 61 days would have been positive, but I am not sure if these illnesses would have delayed my seroconversion if I was hypothetically infected with HIV. I still have a painful lymph node in the back of my neck, and what looks like to be an ear infection.

Thank you for your help.
