Hi lisa, When the urine looks normal and blood is detected only by microscopic examination , the condition is known as Microscopic haematuria. A normal individual can excrete small amount of blood in urine daily ( up to one million red blood cells (RBC) in the urine each day) and the condition is not considered hematuria. In females, hematuria is common due to the high incidence of urinary tract infection (due to their short urethra). Urinary tract infection is usually associated with burning micturition, frequency and urgency. Other conditions that lead to hematuria include Kidney and ureteric stones , in which pain (colicky ) is usually present. Kidney disease, such as nephritis . Medications such as Warfarin, Aspirin, Ibuprofen and naproxen To investigate the cause your doctors would recommend you one or more of the foll lowing tests , after complete history and physical examination, Urine tests (urinalysis), in this case not only to check for blood in urine but also for pus cells which if present indicate the presence of infection. Urine Culture is to be considered in this condition. Blood tests to check also for infection and to rule out any systemic causes of bleeding tendency.
