Determination of Blood Ammonia Using the Ammonia Checker [PDF]
Annals of Clinical Biochemistry: International Journal of Laboratory Medicine, 1983 A new diffusion method employing bromocresol green for determination of blood ammonia (Ammonia CheckerR) using disposable reagent test-plates and a pocket-size colorimeter with direct readout of results was compared with an enzymatic method. The values obtained with the Ammonia Checker were slightly lower than those with the enzymatic method.
