The results of the Clinitest are abnormal, but can be reported. Because this specimen was from a child, the Clinitest was performed routinely even though not indicated by the results of the Multistix. Due to the fact that the Multistix is specific for glucose and was negative, therefore a nonglucose reducing substance is present. Further confirmatory testing such as thin-layered chromatography is needed for identification of the non-glucose reducing sugar.
