hi
thanks for posting on hcm.
your results say that you are not infected.
hiv testing is primarily done by ELISA which is a screening test, if it is negative for the first time it is repeated again after 6 weeks if it still comes negative usually most of the cases it will be negative but there is a chance to say in lay terms that infection in the body is not in a detectable stage what we called window period so we repeat ELISA again within 3 to 4 months period if it is still negative then it confirms no infection, if it comes as positive at this stage WESTERN BLOT TEST is done to confirm, if it is negative nothing to worry, if it turns out to be positive it confirms the infection.
if the initial ELISA is positive , then WESTERN BLOT test is done to confirm if it is positive then infected if negative no need to worry.
hope this is helpful.
regards
