Ok, that doesn’t surprise me. However, the point is the same. If PKU can be diagnosed (or at least a positive urine test can suggest that PKU needs to be tested for), phe is excreted in urine in higher concentrations in PKUers. Actually, this is the statement in Wikipedia regarding what is actually tested in urine, though it is missing a citation, which means that the source of it is questionable: “When PAH is deficient, phenylalanine accumulates and is converted into phenylpyruvate (also known as phenylketone), which is detected in the urine.”
