This study looks at how blood disorders, which are problems related to blood, develop over time. It is called a "longitudinal" study because it follows people for at least 15 years to see how their conditions change. The study is "observational," meaning it doesn't give any treatments, but watches and collects data. Participants are divided into groups based on their specific conditions, like Hemophilia, which is a bleeding disorder, or Thrombosis, which is a clotting disorder. Data is collected every 6 months and yearly through various modules, or smaller studies within the main study.
- Study duration is at least 15 years.
- Participants visit the study site every 6 months and annually.
