This is a research study that asks people with sickle cell disease to donate blood samples and allow researchers to review their medical records and history. By collecting samples and information from many patients over time, researchers hope to better understand why sickle cell disease causes pain crises and other complications, and to identify new ways to prevent or treat these problems.
Right now, doctors don't fully understand why some people with sickle cell disease have more severe pain crises or complications than others. This study exists to gather biological samples and medical information that can help researchers uncover the underlying causes of the disease and develop better treatments.

You will have an initial medical history and physical examination, and routine blood tests may be done to check your diagnosis and how your disease is doing. The study team may continue to collect and store your blood samples and medical information over time, and they may ask to use samples and data from your previous NIH research visits. Your regular medical care will continue as usual, and any additional tests will be discussed with you and your doctor.
