Last answer.  Your results are conclusive. You did not get HIV from the encounter you are worried about.  There is no need for further testing.

This will be my last answer.  Further questions will be deleted without comment.  EWH

That is mean no risks . And my last blood tests results 36 days & 56 days after exposure are conclusive , no need to worry about HIV infection , even if I got rash now 8 weeks about after exposure , I think early HIV symptoms starting from 2 weeks until 6 weeks from possible exposure not more right . Thank you a lot

Still no punctuation and still no risk and no change in my assessment or advice.  EWH

That is mean even if the lab technician used old gloves while withdrawing my blood and he touched the blood withdrawal place by his gloves there is no risk HIV can not transmit through it because I am not sure he used a new gloves and I am worry if he used it with other person and touched his infected blood , my p24 combo tests were 36 days the first one and 56 days the second one after possible exposure both of them negative but I read in some articles you must test 90 days after possible exposure to get reliable result my exposure was oral sex I am receiver by condom then I moved on her butt and teased it out without penetration just out side friction while friction the condom went out and I touched her breast that is now I have some rush I don't know why red spots

Welcome to the Forum.  Your questions are difficult to read because you do not use punctuation.  Please do so in the future.

The combination HIV p24 antigen/HIV antibody test provides reliable test results at any time more than 28 days after an exposure and should be believed.  Thus it is not at all surprising that you got the same test result at 36 and 56 days.  This proves you did not get infected from the exposure you are concerned about.  There is no reason for additional testing.

Your concerns about having gotten HIV when the technician drew your blood at the lab or from possible trauma related to wearing a slipper that someone else wore before you is misplaced.  These are both no risk events.  Laboratory technicians do not re-use materials and there are no cases of HIV due to transfer of the virus from person to person in the process of drawing blood at a commercial laboratory.  

You have no reason to worry.  EWH
