A comparison of the serum tyrosine, DOPA, tryptophan, tyrosinase and tryptophan pyrrolase levels of vitiliginous patients with those of normal subjects show abnormalities in all these parameters. As the clinical diagnosis of vitiligo may be made without difficulty, these parameters appear to be of little diagnostic value in vitiligo. But they may be considered as additional biochemical parameters in vitiligo.
白癜风患者与正常受试者血清酪氨酸、多巴、色氨酸、酪氨酸酶和色氨酸吡咯酶水平的比较显示，所有这些参数均存在异常。由于白癜风的临床诊断并不困难，这些参数在白癜风中似乎没有什么诊断价值。但它们可被视为白癜风的额外生化参数。
