Microscopic hematuria is the finding of blood on a urine dipstick or by seeing red blood cells in the urine under microscopic magnification. Often, women with microscopic hematuria have no symptoms but their doctor finds blood on a routine urinalysis. A patient with microscopic hematuria can not see the blood in their urine with the naked eye. A patient who sees blood in their urine should contact their doctor as soon as possible.
A patient with microscopic hematuria may have something in their history that helps determine why they have blood in their urine. These include a recent or current urinary tract infection, a recent upper respiratory tract infection, a family history of kidney disease, flank pain (possible kidney stones), menstruation, trauma, recent travel, and certain medications.
Oftentimes, we are unable to determine the exact cause for microscopic hematuria.
