How long will it take for an HIV test result to turn positive?
It depends upon the type of test. For someone with symptoms suggestive of acute HIV infection, a blood test called an HIV viral load can immediately determine if HIV infection is the cause of the symptoms. The more standard antibody test will turn positive in about 95 percent of people within three months of becoming infected. If your antibody test is negative six months after potential exposure, your chances of having contracted HIV at that time is close to zero.
