Exclusion Criteria
Patients who are transplanted but do not fulfill any of the above mentioned criteria
The purpose of this study is to collect blood specimens and data from patients undergoing a stem cell transplant. Stem cell transplants are procedures where patients receive blood-forming stem cells to replace damaged or diseased bone marrow. This study aims to gather information from patients who have certain conditions or treatments related to their transplant.
Participants in this study will have blood samples collected and data recorded as part of their regular medical care. These procedures are done to monitor health and treatment progress. The study will include various tests and evaluations to ensure comprehensive data collection.
- Who can participate: Adults aged 18 and older undergoing a stem cell transplant may participate. Eligibility includes a history of liver disease, high-risk transplant features, or certain high-risk diseases. Key factors are specific liver conditions, high-risk transplant regimens, and certain blood or genetic disorders.
- Study details: Participants will provide blood samples and medical data as part of their regular care.
