define urates infant
Urate crystals (commonly called brick stain by doctors) are a combination of calcium and urate, substances normally found in urine. Crystals of the substance often form, leaving a red-orange stain in your baby's diaper â which can be alarming for parents! Any baby can spill urate crystals, though it's more likely when a baby is dehydrated (or even just slightly dry) as the urine becomes more concentrated.
