Based on Shaw's specific test, the adrenaline content of the urine of some normal individuals was considerably higher than has been reported by those using the von Euler technic (adsorption at an alkaline pH, elution and bioassay). One patient with myocardial infarction showed highly significant amounts on four occasions.
