==Background==
*Common cause of red, pink, or orange urine in neonates
**Occurs mostly in the first week of life, but can occur anytime during infancy
*Parents often confuse this phenomenon with blood, leading to presentation to ED<ref>Küpeli S, Yurdakök M, Kilinc G, Bilgetekin E. Urinary uric acid levels and discoloration of diapers in healthy neonates. Pediatr Nephrol. 2005 Sep;20(9):1361-2. doi: 10.1007/s00467-005-1934-5. Epub 2005 Jun 8. PMID: 15942785.</ref>
*Often due to dehydration and relative immaturity of kidney's concentrating abilities
**Breastfeeding may increase uric acid crystalluria due to its high protein content, which acidifies urine and promotes urate crystallization

==Clinical Features==
*Reddish, pink, or orange urine noted in diaper
*History of breast-feeding and/or dehydration
*Baby is otherwise well-appearing (suspect alternate diagnoses if has colicky symptoms or febrile)

==Differential Diagnosis==
*For female neonates, consider withdrawal bleeding due to lack of maternal hormones
*Consider other serious causes, including obstructive uropathies, [[porphyria]], familial/genetic causes of hyperuricemia<ref>1.
