title: Biologic banking in cohort studies, with special reference to blood.
abstract: Those who conduct cohort studies in cancer epidemiology increasingly use biochemical analyses as an important component. Some of the potentially important considerations when banked blood is used include the conditions and temperature of storage, effects of thawing, and the stability of specific substances under prolonged subfreezing temperatures. I have reviewed a selected number of biochemical substances.
