Classroom Demonstration of a Spot Test for Phenylpyruvic Acid and Its Relationship to Phenylketonuria  Christopher J. Halkides
A classroom demonstration of a spot test for phenylketonuria using ferric chloride is discussed. The chemistry is similar to that used in Phenistix test strips. Some background information on screening infants for phenylketonuria is also given.
