There can be many causes for blood in the urine. Examples would include urinary tract infection, kidney stones, kidney or bladder disease.
Even if there isn't visible blood, a urinalysis should be obtained to look for microscopic blood. Tests to consider would be a CT scan looking for kidney stones, or a cystoscopy to evaluate the bladder.
These options can be discussed with her personal physician or a urology referral.
Followup with your personal physician is essential.
