As dona­ti­ons are always vol­un­ta­ry, it is pos­si­ble to with­draw – without having to sta­te a
rea­son – befo­re the pati­ent under­goes pretre­at­ment. If you are eli­gi­ble to dona­te, you will be
invi­ted by your donor cen­ter to attend a detail­ed talk, whe­re you will have the chan­ce to make
your final decisi­on. Howe­ver, if the tre­at­ment pro­cess has alrea­dy star­ted the pati­ent will be
depen­dent on a trans­plant. A life-threa­tening situa­ti­on will other­wi­se develop.
