question: Hi doctor, I am 29 years old. I had protected sex with a call girl before five months. But, I want to confirm whether I was infected with any disease. I have read on the internet that window period for HIV is three months and hence to confirm I have undergone HIV testing called ELISA. The result of which is non-reactive and the value is 0.062. Again, now I repeated the test and it showed result as non-reactive with the value of 0.104. The two reports have been attached here. Regarding symptoms, I did not develop any fever or allergy in the last four months. Is ELISA test reliable? Is there any need for me to take any other test or repeat the test? Can I stop worrying as I have already covered window period? Why did the test show some value like 0.6 and 0.104? Does it indicate the presence of any disease? What is the window period? Please help me in detail as I am much worried.
