Biological samples from patients and donors are valuable. This is the guiding principle behind the work carried out in the biobank. In the biobank, biological samples are stored under standardized conditions and at very low temperatures (often for long periods of time) and made available to science and research as needed. Research using a large number of samples from many different people enables scientists to find answers to questions such as these: Are there differences between biological samples from people of different genders, ethnicities, and ages? Does a (new) drug work the same way for everyone? Or to put it another way: If a treatment helps some individuals, does it also help most people?
