HBG2 and Hematuria: Red urine is generally due to hematuria, but vegetables like rhubarb, beetroot (due to betalain and seen in 10 to 14% of population), and blackberries [8]; metabolites like methemoglobin, melanin, porphyrin, and homogenitisic acid; medications like chloroquine, deferoxamine, ibuprofen, iron sorbitol, nitrofurantoin, phenytoin, rifampicin, vitamin B12, doxorubicin, phenazopyridine, phenolphthalein, and topical application of azosulfamide (alternative/complementary medicine) can also cause a similar discoloration [8].
