Biological samples from patients and donors are valuable. The work in the biobank is subordinate to this heading. Biological samples are stored in the biobank under standardized conditions and very cold temperatures (and often for a long time) and made available to science and research as required. Research on a large number of samples from many different people enables scientists to find answers to questions like these: Are there differences between biological samples from people of different genders, ethnicities and ages? Does a (new) drug have the same effect on all people? Or to put it another way: if a therapy helps individuals, does it also help most people?
