Question: 

Hello,
Please allow me to raise some questions/concerns related to HIV topic.
1. On the result of my serology test, it is indicated as follows:
SEROLOGIE DE DEPISTAGE VIH1-VIH2
Dépistage par électrochimiluminescence sur COBAS Elecsys 411
VIH 1/2 et Ag p24 (HIV Combi PT Cobas / ROCHE) : Négatif
According to the above information, could you please tell/confirm wether it is of the forth-generation assay?
2. After the exposure, I did take the PEP.
Is the PEP able to delay the conclusiveness of the serology test assay (even with the forth generation)?
First test at 31 days after the exposure (1 day after I finished the PEP); VIH 1/2 et Ag p24 (HIV Combi PT Cobas/Roche) : Négatif
Second test at 45 days after the exposure (15 days after I finished the PEP): VIH 1/2 et Ag p24 (HIV Combi PT Cobas/Roche): Négatif
For reassurance, at the 45th day post-exposure, I also requested to perform the Viral Load HIV test.
Conclusion: HIV-1 RNA non detected.
In most articles I have found, it is recommended to have a confirmatory test at 3 months post-exposure.
Waiting for the next test is still very stressful and anxious for me.
Thank you in advance for your answer.

Answer: 

Thank you for your inquiry. From what we gather from the question, you are asking if the serology VIH1-VIH2 test that you had taken is a fourth-generation test.

Unfortunately, we are unable to confirm if this is a fourth-generation test.

In regards to your later question, we gather you are asking about confirmatory tests being taken 3 months post-exposure.

It is recommended to get confirmatory tests taken, but this is reliant on the type of test. We recommend you refer to your physician for more personalised answers to your questions.
