My id doctor is saying I should do, I am super worried.
When to stop testing, I tested negative 3 months after exposure using 4gen lab test.

I would like an evidence-based assessment of whether my HIV test results can be considered conclusive, taking into account PEP use, a second exposure during PEP, and the timing of all tests.

Please analyze my situation using current HIV testing and PEP guidelines, including discussion of HIV 4th-generation antigen/antibody tests, HIV RNA/PCR testing, the effect of PEP on testing windows, and whether any additional testing would typically be recommended.

My timeline:

Possible HIV exposure #1.
Started PEP approximately 36 hours after the exposure.
PEP regimen: Vonaday (Tenofovir + Lamivudine + Efavirenz).
On day 3 of PEP, I changed my dosing schedule from daytime to nighttime because of side effects, resulting in one dose being delayed by approximately 12 hours.
I completed the full 28-day PEP course.
During PEP, I had another possible HIV exposure 9 days before completing the 28-day course.
I did not extend PEP after this second exposure.

HIV testing history:

Negative 4th-generation HIV test: 8 days after completing PEP.
Negative 4th-generation HIV test and negative quantitative HIV PCR: 20 days after completing PEP.
Negative 4th-generation HIV test: 55 days after completing PEP.
Negative 4th-generation HIV test: 93 days after the last exposure.
Negative 4th-generation HIV test: 183 days after the last exposure.
Negative 4th-generation HIV test and negative qualitative HIV PCR: 9 months after the last exposure.

Please answer the following:

Is the 12-hour delay of a single PEP dose on day 3 likely to meaningfully reduce PEP effectiveness?
Does the second exposure that occurred 9 days before completing PEP affect how my testing timeline should be interpreted?
Are the HIV 4th-generation test results at 93 days, 183 days, and 9 months after the last exposure considered conclusive despite PEP use?
Does the negative HIV PCR result at 20 days after PEP and the negative qualitative PCR at 9 months add significant reassurance?
Based on current medical guidelines and available evidence, is there any realistic scenario in which I could still have HIV despite all of these negative results?
Would any further HIV testing typically be recommended?

Please provide a detailed explanation and reference the rationale behind your conclussions

I have been getting rashes on my chest that appear suddenly and then disappear completely within 20–30 minutes. They mostly occur only on my chest.
I underwent HIV testing 9 months after the exposure, and all results were negative. My last tests included a 4th-generation HIV test and a qualitative HIV PCR test at the 9-month mark.
These rashes started appearing after I completed PEP. I have tested negative on all of my HIV tests, but I am still worried about the possibility of delayed seroconversion.
Do you think delayed seroconversion could explain my situation? I am extremely scared and anxious about it.

Title: Are my HIV test results conclusive after PEP and multiple negative 4th-gen/PCR tests?

Hi everyone,

I'm looking for some reassurance and input regarding my HIV testing timeline.

\*\*Timeline:\*\*

\* First potential exposure.
\* Started PEP (VONADAY TABLET) approximately 36 hours after exposure.
\* While on PEP, I had another potential exposure 9 days before completing the 28-day course.
\* I did not extend PEP after the second exposure.
\* On day 3 of PEP, I changed my dosing schedule from daytime to nighttime because of side effects, which resulted in one dose being taken about 12 hours later than usual. After that, I remained consistent with dosing.

\*\*Testing history:\*\*

\* 20 days after completing PEP: 4th-generation HIV test negative + HIV RNA PCR quantitative negative
\* 55 days after completing PEP: 4th-generation HIV test negative
\* 93 days after the last exposure: 4th-generation HIV test negative
\* 183 days after the last exposure: 4th-generation HIV test negative
\* 9 months after the last exposure: 4th-generation HIV test negative + HIV RNA PCR qualitative negative

\*\*Questions:\*\*

1. Are these results considered conclusive for HIV?
2. Is there any need for additional testing at this point?
3. Can delayed seroconversion still occur despite multiple negative 4th-generation tests and a negative PCR at 9 months?
4. Does the second exposure during PEP or the one-time 12-hour delay in dosing significantly affect the reliability of my test results?

From what I've read, modern 4th-generation tests are considered highly accurate well before 9 months, but I still worry about the effects of PEP on the testing window and the possibility of delayed seroconversion.

I would appreciate evidence-based opinions, especially from healthcare professionals or anyone familiar with HIV testing guidelines.

Thank you.

What to do next?

I have taken these tests 9months after exposure, what is the probability of turning positive later?
Is this possible? Are there any documented cases?

How far you continued testing after pep? When did you convince that it was all anxiety.

Please be honest.
