Close agreement was found between respective estimates of blood CO 2 flux rate (193 and 199 gC/day) and labelling in plasma glucose (14.9 and 15.5%) when Na 2 13 CO 3 and Na 2 14 CO 3 were infused together into eight sheep for 17 h. From an infusion of Na 2 13 CO 3 and [ 14 C] glucose a model describing carbon flows through blood CO 2 and plasma glucose was similar to that obtained from [ 14 C] tracers infused on separate occasions. Key words: [ 14 C] tracers, [ 13 C] tracers, glucose flux, CO 2 flux, sheep
