The measurement of ammonia in whole blood, erythrocytes, and plasma.

Abstract 1.1. A new method for the measurement of ammonia in blood, erythrocytes, plasma, or other labile biologic systems has been described. 2.2. Conditions which produce falsely high or low values encountered in other methods are avoided. 3.3. The ammonia found in freshly drawn human venous blood is believed to be preformed true ammonia, present as ammonium ions and not an artifact. 4.4. The ammonia content of blood, erythrocytes, and plasma in 29 patients free of liver disease is reported. 5.5. Ammonia in erythrocytes is 2.8 times that found in plasma.
