I distinctly remembered the nurse saying brick dust but didn't remember anything else so I did a quick google search and found this:

Bloody Urine
Actually, blood in the urine is always abnormal. However, infant s urine may normally contain significant amounts of uric acid. These crystals get trapped in the diaper liner and appear like red brick dust. If the "blood" in the urine has this appearance, it is probably not really blood but uric acid crystals. http://kidsgrowth.com/resources/arti...ail.cfm?id=864

It's still a good idea to check with the doc to be sure. Good luck!
