Brief Answer:
I suggest to repeat at 28 days.

Detailed Answer:
Hello,
Thank you writing in healthcare magic.

A duo HIV test after 22 days is accurate but if you had a risky sexual intercourse I suggest to repeat it after 28 days and than after 3 months as a conclusive test.
You should know that duo test (ab/ac) after 3 weeks could detect p24 but it depends from person to person and that is why we suggest to repeat it.

I hope my answer helps you.

Brief Answer:
You are free of HIV.

Detailed Answer:
Hello,
Thank you writing back.


I have read carefully your history (just kissing ,touching and no sexual intercourse ) and I think you shouldn't worry because there is no risk for HIV and STI.
So, based on this situation I think that Duo test after 22 days is very accurate and you don't need to do other Duo test because you are definitly free of HIV.
The only risk in this situation is to get HSV1 from kissing and syphilis if she had cutaneous elements during this time.

I hope my answer helps you.

Thank You Mam
Permit me to close off the discussion
Based on our conversation, I did a repeat DUO testing yesterday in Singapore. This was on 29th day. The. Result was negative.. The syphillis test was also done on 22nd day along with duo which was also ok. The doctor mentioned that for HSV the testing is normally recommended when there is an outbreak.
And that they would normally do after 3 months..
I hope I can move on frm this episode.
