User :   (1) HIV-1 Antibody, Confirmation Western Blot Value:
User :   so the last exposure was only 7 days before the test
Doctor :   Ok
User :   what is meant by value

User :   but its
User :   but its
Doctor :   All test where there are no observable antibodies are too mentioned as the same.
Doctor :   I mean, no test will mention that the results are 0.
User :   oh k
User :   what is meant by "non-reactive"?
Doctor :   The value
Doctor :   To understand what non reactive means, you will have to know how this test is done.
Doctor :   In simple terms, the test uses reacting a sample(in whom antibodies is to be checked) with a test sample which will have the antigen obtained by HIV Virus.
Doctor :   If antibodies are present in the sample, they will react with the antigens.
User :   oh k
Doctor :   This reaction is seen as a change of colour.
User :   so 7 days are too(very) early to get tested with HIV DNA PCR test?
Doctor :   Hence non reactive essentially means that the sample doesn't contain any antibodies to react with the antigen.
Doctor :   HIV DNA PCR test are the most sensitive test, which can give results in less than 3 weeks time.
Doctor :   A negative HIV DNA PCR essentially means you are non infected.
Doctor :   There won't be any seroconversion.
Doctor :   However, yes, less than 6 days is a little early.
User :   in the medhelp site, Dr HandField (one of the hiv specilist) addressed that it is a test which normally should take on 7-20 days of exposure
User :   your openion on this quoted numerbs 7-20 days?
Doctor :   Yes, the effectiveness of this test is better after 3 weeks.
Doctor :   This is an average calculations though.
Doctor :   The test is highly sensitive, which means even a small trace of HIV if present can be detected by the test.
Doctor :   Hence a negative result faily rules out an infection.
User :   so what do you recommand to me next?
User :   mine was only 7 days after exposure
User :   but considering the overall exposures which staretd at Oct 25th and ends at Den 6th
User :   *Dec 6th
Doctor :   As explained to you earlier by me, the rest of the doctors and the specialist, the chances of you getting HIV infection through you exposure is almost nil.
Doctor :   And there is no need of you to worry.
User :   but the specialist answered me, looks like my chances are high from the cuts and rubbing finger on eyes
User :   that worried me a lot
Doctor :   She meant the chances of other bacterial/fungal infections and not HIV.
User :   ooooh
User :   is this bacterial/fungal infections includes STDs?
Doctor :   It doesn't appear like an STD infection,
Doctor :   Since you don't have symptoms, I mean you don't have the infections now.
Doctor :   She meant, if you continue, you can get them in the future.
User :   i have only dhiarriaa...but not exactly.....only in loquid form....but still only once a day
User :   sorry....its not in liquid form
Doctor :   That is fine, and not a sign of bacterial infections.
User :   thanks for the useful information Doctor
