An ELISA test is never to late.
I hope you have not been worrying about this for 10 years.
ok thank you too much for your support but i have only small question does this mean that when you do elisa 1 and 2 test after too much time of your un safe relation its result will be accurate 100% even if you are in hiv late stage ?
Of course it will be accurate. As long as you haven't put yourself at risk less than 3 months before testing.
