CDC amerikanın en büyük bulaşıcı hastalıklar bilgisi veren kuruluş.
For example, if your health care provider uses an antigen/antibody test performed by a laboratory with blood from a vein you should get tested again 45 days after your most recent exposure. For other tests, you should test again at least 90 days after your most recent exposure to tell for sure if you have HIV.
4.nesil 45 son diyor. 3 nesil testler için 90.günden sonra yaptırmak yeterli diyor.
