Every state currently allows minors over the age of 12 to receive testing for sexually transmitted diseases, including HIV, without parental consent. Most of these states allow minors to receive treatment for all sexually transmitted diseases without parental consent; however, three states—California, New Mexico, and Ohio—as of 2002 do not allow minors to receive treatment for HIV without parental consent. One state, Iowa, requires that parents be notified in the event of a positive HIV test. Many states allow doctors to notify the parents of the results of tests and treatment for sexually transmitted diseases, though they do not require the doctor to get a consent.
