ferÂ·ric chloÂ·ride test. a qualitative test for the detection of phenylketonuria; the addition of ferric chloride to urine gives rise to a blue-green color in the presence of phenylketonuria.
After incubation, 10% ferric chloride is added to the media; if phenylpyruvic acid was produced, it will react with the ferric chloride and turn dark green. If the medium remains a straw color, the organism is negative for phenylalanine deaminase production.
