Summary

Description
English: Change in urine color before and after sun exposure Left figure is urine of the first day. Right figure is urine after sun exposure for 3 days. Urine color changed to “port wine” color after sun exposure. This color change is due to increased concentrations of porphyrin intermediates in the urine, indicating an abnormality in production and a partial block within the enzymatic porphyrin chain with metabolite formation. The urine color usually becomes darker with acute illness, even dark reddish or brown after sun exposure.
中文（繁體）：​左側為第一天尚未曝光的尿液，右側為曝光三天後的尿液呈現波特酒顏色。此顏色變化是由於尿液中porphyrin中間物增加，表示porphyrin代謝途徑阻礙。尿液顏色隨疾病惡化而變黑，在曝光後呈現暗紅或棕色。
