Laboratory studies have been made to evaluate two methods for removing ammonia from blood:-1 The twin-coil artificial kidney was found to produce significant reductions in the ammonia content of outdated human banked blood. After one passage through the coil, levels of up to 9 mug. of ammonia nitrogen per millilitre were reduced to normal, and this effect was maintained when up to 5 litres were passed.
