NO IT DO NOT MAKE ANY DIFFERENCE BECAUSE HIV DUO LOOKS FOR BOTH ANTIGEN AND ANTIBODY AT SAME TIME.IT IS EXTREMLEY RARE AND HIGHLY UNLIKELY THAT YOUR DUO TEST HAS NOT PICK UP ANTIGEN OR ANTIBODIES AT 7 WEEKS SO IF YOU HAVE TWO HIV DUO WITH A DIFFERENCE OF 2-3 WEEKS THAT WILL MEAN YOU ARE ALMOST NEGATIVE BUT AGAIN ACCORDING TO TESTING GUIDE LINE YOU HAVE TO FOLLOW THIS UP AT 12 WEEKS FOR CONCLUSIVE RESULT.
what about testing at 7 weeks, does it make any difference?

1)'Fourth generation ELISA for HIV1/2' is a HIV DUO TEST (Antibody and Antigen Sandwich Test) .It actually looks for the P24 (protein) Antigen and Antibodies simultaneously.
2) P24 Antigen is almost always present in the body after acquiring the virus till the 4th week after infection and then it disappears .
3)Once the P24 antigen disappears,antibodies starts to show up.
4) ' Fourth generation ELISA for HIV1/HIV2' detects both P24 antigen and antibodies 3 weeks after the exposure.
5)HIV DUO test is said to be best at 28 days and 6 weeks after the exposure.
6) Fourth generation ELISA test sensitivity is >99.5% and specificity >99% to both B and non-B subtypes. If a person has taken the test at the 6 week post exposure.
So I recommended you to do 'Fourth Generation ELISA for HIV1/2' i.e HIV DUO test 6weeks after the exposure.
However 12/13 week testing from any generation of ELISA is compulsory for conclusive results according to testing regulations in most of the nations.
A negative results on 6 weeks by 'Fourth Generation ELISA for HIV1/2'
would mean that you would have extremely extremely....extremely low chances to be HIV + in 12/13 weeks .
Stay Calm and Chill there is nothing to worry about .
Always use condoms properly and never share needles.
