CMIA combo ag/ab 28 day

[Worriedguy3028]

I had exposure  2 month ago 21/06/2018 with female of unknow status protected vaginal unprotected oral , deep fk and culininggus but  dont know is do the condom stay intact or failed during the intercourse . then i took duo/combo test ( cmia ag/ab combo written on the paper ) at 19/07/18 with non reactive result. No symptoms so far except panic attack that come and goes everytime i remember the incident, what i want to ask is :

1. The time i took the test not exactly 28 day the exposure happen during the night of 21 june at 19:00pm and the combo test taken at 19 july afternon 10:00 am   ( 27 day 15h ) after exposure considered 28 day after exposure , did i miscalculated the date and should have take the test the day after.

2. Should i take another test at 3 month mark considering my encounter is low risk.

3. Did i take the correct test ? ( cmia combo )

Yes i understand my situation is no risk , but i promise this will be my final question i wont ask anything after this.

    On the test result paper it says
    Anti-HIV
    HIV ag/ab combo ( CMIA ) method
    0.06 Non reactive

    Is this correct test that look for
    antigen (p24) or just antibody test ?

Because believe it or not the first lab im planning to take test says that they use CMIA but antibody only , so i took another test at different lab and you can see the resul above. I jusg want to know if take the right test or not.

You can read it any way you want, since you are negative.

That exposure you mentioned is not a risk therefore never a need to test at all,anyway since you did test at 27th day with DUO test,those test are very sensitive and only had a window of 28 days period.

Okay thx for the reply , one more question so eventough my calculation date from the day of exposure is 28 day 9 hour short ( 27 day 15h) it still count as 27 day ? Will it make a difference if i did the the test day after ?

You had zero risk for HIV.  It doesn't matter when you take the test.  It will always be negative since you had ZERO risk for HIV.
