Ans. A biological specimen which is also called a biospecimen refers to a biological laboratory specimen which is held by a biorepository and is used for research. Such a kind of specimen would be taken with the help of sampling so that it can be a representative of any other specimen which is taken from the source of that specimen. When the biological specimens are stored, they ideally remain equivalent to the freshly-collected specimens for the purposes of different kinds of research.The human biological specimens are stored in the type of biorepository known as a biobank, and the science of preserving these biological specimens is the most active when it comes to the field of biobanking.
