Hai Srinivasa, You need not worry about all these values. You are negative for HIV at present as per the test. For every test they have designed in such a manner to say it is positive. That is the ct off value. The ELISA test you had been assessed have a cut off value as 0.4. Any thing above 0.4 is considered to be test positive. As far as your test value concerned, it is just 0.003, far lesser than the cut off value . This means you are not having HIV. Anyhow it all depends when you had your last risky sexual contact. If it is within 3 months duration, You have to repeat the test once again. If already it is more than 3 months time, then you just ignore and forget about the past and always adapt a safer sex with condoms. Have a nice day. Dr SM
