The accuracy of blood tests for STDs varies, depending on the type of infection being tested for. For example, HIV blood tests are highly accurate, with a window period of about up to 3 months from the time of infection for 3rd generation tests and 28 days for 4th generation tests. Syphilis blood tests are also highly accurate, but have a longer window period of about 3 months.
