I signed up for the Chinese bone marrow bank when I donated blood last year. At that time, I filled out the form and drew blood. I don't know if it was successful. How to inquire?

If the initial matching is successful, the Red Cross will contact you. If you want to inquire about your warehousing information, you can contact the local Red Cross Society. They have a department in charge of the hematopoietic stem cell database. If your information changes, you can contact them to modify it. Some time ago, I just contacted the Provincial Red Cross Society, inquired about my warehousing information, and modified my contact information.
