Objectives
Narrative objectives1 In this exploratory study, we aimed to establish an more convenient diagnostic method for differential diagnosis of hereditary porphyria (especially, VP, HCP, EPP) by detecting the intrinsic fluorescence spectra of porphyrin intermediate metabolites (Uro III, Copro - III, Pp - IX) in urin/stool samples.

Assessment
Primary outcomes The differential diagnosis of hereditary porphyria (especially, VP, HCP, EPP) by detecting the intrinsic fluorescence spectra of porphyrin intermediate metabolites (Uro III, Copro - III, Pp - IX) in urin/stool samples using LCTF
Key secondary outcomes 1)Correlation between intrinsic fluorescence spectrum of porphyrin intermediate metabolite and results of HPLC analysis, genetic test(previously obtained).
2)Discrimination of difference in detectability by various clinical samples (urine/stool)
3)Correlation between intrinsic fluorescence spectrum of porphyrin intermediate metabolite and clinical data (gender, age, blood biochemistry data)
