when the time you can tell

If you had exposer  how long does it need to test on elisa . If taken Western blot and Elisa,  can you resure you dont have hiv . there so much stories about window period . Thanks

you need to test 6 or 8 weeks after your exposure then must have a conformatory test on the 13 week for a definitive result. western blot testing is only used to confirm once your antibody test becomes positive. if you have followed the proper testing guidlines and recieve a negative result on the 13 week mark is it considered definitive and conclusive. but make sure to have other std's test as well since STD's are much more easier to catch than HIV.
