Hello,
Thanks for query.
Although HIV 2 infection is very low, but it is always better to get tested.
Its good that you have got dna PCR done.
It is the most sensitive test available and can detect even a single virus in your body,
This test gets positive even within a week of contact.

Let me know if you have any other doubts.
Wishing you good health.
Thank you

Hello,

Thanks for the follow up.

Yes, dna PCR is good enough, you don't need another test.

For HIV-2 also you can do dna PCR.
Else you can go for 4th generation ELISA, however this test can be done only after 3 months.

In my view you can just relax, if HIV-1 is negative.
HIV 2 is seen only in African countries.

Let me know if you have any other doubts.

Thank you,
