<qa>  What is the name of the test that you will have at the ScreeningWashoutSCREENINGWASHOUT PHASE: Your study doctor or his staff will review with you any medications that you are currently taking and may instruct you, if appropriate, to discontinue taking certain medications. Your study doctor or his staff will explain how long you need to stop taking each drug before you can start the study. Depending on the type of medications you may be taking, the ScreeningWashout Visit Visit 1 of the study may have to be completed in two visits. The screeningwashout phase may take up to 90 days. If you agree to participate, the study doctor or his staff will carry out tests to see if you are eligible for this study. At the ScreeningWashout Visit, you will have a medical and psychiatric history review including medications you have taken for treating Tourette Syndrome and a physical examination including sitting blood pressure, pulse, temperature, weight and height. A blood sample will be taken approximately 2-3 teaspoons and tested to rule out any abnormalities. You will be asked to give a urine sample that will be tested for drug use and, if you are a female that is capable of having a child, to ensure that you are not pregnant at the time of study entry. The pregnancy test must be negative for you to continue in the study. Additionally, you may not currently be breastfeeding to continue in the study. You will undergo a medical and psychiatric evaluation. You will be asked to answer questions using scales, including one that measures the severity of your symptoms of Tourette Syndrome and one that measures your symptoms, if any, of attention deficit hyperactivity disorder A-DHD.
