In porphyria patients, urine will present in various colors.The general spectrum runs from reddish wine to dark brown tea colors. Urine collected in a glass container and set in the sunlight will darken significantly in porphyria patients. This video is proof of that. Someone who has porphryia most specifically hereditary coporprophyria (HCP), their urine will change color in the sun even if they are not having a acute porphyric attack. As you can see by placing urine samples side by side, this shows proof of porphyria. During an acute attack, the urine would be much darker after being placed in the sun.
