The term "brick dust" urine refers to the gross appearance of the urine specimen.
A brick dust urine shows small particles of reddish or brownish material in the sediment.
Differential diagnosis:
(1) uric acid and/or phosphate microurolithiasis
(2) drug crystals
(3) fragmented blood clot (usually in the setting of recent hematuria)
Brick dust urine is seen due to urates in breast-fed neonates, especially if they are dehydrated.
