In most countries you can write to "your" patient from the day of your stem cell donation.
Due to an anonymity period of at least two years, contact may only take place anonymously by letter or email. In order to guarantee compliance with the anonymity period, we act as intermediaries for anonymous correspondence. You as the donor send the letter to us and we forward it to the patient via the responsible transplant clinic. Please be sure to include your donor number in anonymous correspondence, as this is the only way we can allocate your letter accordingly. The letter to the patient will be proofread by a DKMS staff member. We are obliged to delete all references that endanger anonymity and ask for your understanding. This includes, for example, your name, initials, place of residence or similar details that allow conclusions to be drawn about your person. If "your" stem cell recipient or "your" stem cell donor is being treated abroad, please write your letter in English. If you have any questions, please do not hesitate to contact us.
Often donors are waiting for a reply to their anonymous letter, but it is late or may not come at all. Please understand that the patient may need time because he or she may still be ill or simply do not wish to be contacted. Just as contacting the patient is a personal, individual decision for you, it is also a personal decision for the recipient of your stem cells.
We know from experience that many patients only react to the donor's letter after some time. Often they only want to get in touch when their state of health has stabilised and they can report on progress and the nice things.
The anonymity period applies in the UK and most countries in the world. During the first two years after a blood stem cell donation takes place, the donor and patient are generally not allowed to meet in person. There are important reasons for this, for example:
