Biobank is referred as a repository or library that stores biological samples which are intended for research purpose. Biobanks play a pivotal role in biomedical research and stores wide array of biospecimens that include purified saliva, blood, plasma, DNA samples. Biobanks provide data that represent large number of individuals samples used by researchers for multiple purposes (disease identification, genetic trait identification and others). Biobanks help in identifying biomarkers of diseases related to single nucleotide polymorphism and others. The samples in biobanks are categorized on the basis of genetic trait such as age, gender, ethinicity and blood type. Furthermore, samples are also categorized on the basis of environmental factors such as climatic conditions where the donor has been exposed or some other condition that can affect human genes. Biobanks are of three type’s namely virtual biobanks, tissue banks and population banks which are classified on the basis of purpose
