State legislation may require informed consent be obtained before HIV testing is performed. The laws dictate what type of information must be provided to the patient. The patient may have to receive an explanation of the test and its purpose, possible uses of the test, the limitations of the test, and the meaning of the test results. In 2006 the Centers for Disease Control and Prevention (CDC) issued a new screening recommendation for HIV testing on all persons between the ages of 13 and 64 receiving treatment at health-care facilities. The procedure is called opt-out screening or opt-out testing. This means that the patient is told that the HIV screening test is part of their routine care and covered by their general consent for treatment. Patients have the right to ask questions about the procedure and the right to decline (opt-out of) the procedure. This differs from opt-in testing where the health-care provider recommends that the patient have the test and the patient must give written consent. Based on state laws the procedure of opt-out screening may vary or not be an option for the facility to use. In some states an accidental needlestick is considered a significant exposure to the health-care worker, and HIV testing can be ordered by a health-care provider without patient consent. In this situation, the HIV results are not entered into the patient's chart
