What urine analyte would you expect to find in a patient suffering from a kidney stone?

You would usually find blood in the urine.

When someone has a kidney stone, the stone can scrape the lining of the urinary tract as it moves. This often leads to hematuria, which means red blood cells in the urine.

Sometimes you may also see crystals that match the type of stone (like calcium oxalate crystals), but blood is the most common finding.
