This study wants permission to use stored patient specimens (like blood or tissues) for future research, which might include genetic testing (studying genes). These samples are collected during Adult AIDS Clinical Trials Group (AACTG) studies and might have some leftovers. Researchers want to use these leftovers to learn more about HIV and how to treat it better. Patients who participate need to decide if they agree to let their samples be used later for new research. You can also choose to give a small blood sample (14 ml) for future DNA studies. If you don’t agree, it won’t affect your chances to join other studies. It’s important to know you won’t be notified of any test results from these future tests unless there are special reasons. Your identity will be protected, and this decision can be made at any time during or after your participation in an AACTG trial.

• Participation involves signing a consent form.
• No impact on joining other clinical trials if you decline.
• Sample use is for research only, and your identity is kept secret.
