At this visit, you will have a physical exam, including measurement of vital signs (heart rate, temperature, and blood pressure). Blood samples (about 1 tablespoon) will be drawn for routine test and to check for infection. The blood sample may be drawn from the CVC, if the CVC is still in place. The CVC exit site will be examined. You will be asked about any symptoms or illnesses that you may have experienced. In addition, you will be asked to inform the study doctor and/or study staff of any medications or therapies that you are taking.
