Summary

Histamine has been measured in whole blood and in the plasma of twenty-three subjects following exercise testing of seventeen asthmatics and six normal controls. Whole blood histamine rose in both asthmatics and controls and was associated with a concomitant rise in the basophil count. Plasma histamine in the peripheral venous blood only rose in one patient who developed urticaria after exercise.
