Nothing to worry about in relation to hiv
If you had a real risk, a hiv
test at 3 months will be conclusive. Your negative
test at 11 weeks is highly unlikely to change.
Your elisa test result just tells you that your result is negative, meaning no detectable antibodies present at that point in time. The value (0.34) is insignificant, anything below the cut-off value of 1.0 means your test is negative, do not worry about it.
What was your exposure, may i ask?
