Got the result for the test, few question. PLEASE ANSWER!

Last May 30, 2009, I had a needle incident which I suspected to be an exposure. then I got tested last June 25. It was NON REACTIVE with and absorbance value of 0.115, cut off is 0.179, negative value is 0.079 and positive velue is 2.239. Recent I got tested again for a beyond three-month window period, result is: NON REACTIVE but my absorbance value increased to 0.172, nearly the cut off of 0.179. What could this means? And what could have caused the increase? Thank you!

your test is NEGATIVE...PERIOD.   it doesnt matter if the number increased or decreased...and this is normal for ppl who test repeatedly.  as long as you are within the normal "range"...you are good to go :)

YOU DO NOT HAVE HIV.

What could have cause the increase? Does ELISA detects for specific HIV antibodies or are there any antibodies and antigens that they can detect? The Med tech was really wondering what could have caused this and recommended me to get the test again after 3 months. There goes the 6-month window period. I'm really scared to death and I don't know what to expect.

The Med Tech was wrong. As long as it was below the cutoff, the actual absorbance number means absolutely nothing.

It is a binary test- you are either positive or negative (NON-REACTIVE). There are no gradations within the negative category (e.g. you are not 'weakly' negative).

what do you mean that I am not weakly negative? Does it means there is still a possibility that I have IT? That it could show up differently on my next test? I thought ELISA at 3 months is conclusive. I am not under chemotherapy, not immunosuppressed either. (Whatever they mean about immunosuppression. But I am sickly though. Weak immune system). I just can't understand why my absorbance value increased abruptly. By the way sorry for the other post. I thought I was posting it at the experts' forum.
