What does it mean if i have blood in my urine?

Possible infection: You could have a urinary tract infection (bladder infection), a kidney stone or could have blood from another source such as vaginal bleeding. Please call your doctor for evaluation.

Blood/urine =inflamm: It may be due to infection, cancer, trauma, or stone of passageways. Also, glomerulonephritis ( filtering unit diseases) are possible. Need a doctor to differentiate.

Diagnosis First: It depends where it is coming from. It may be from the filtering units, kidneys, ureters, bladder, prostate, or urethra. The presence of other factors in the urine, symptoms, and patient's age all will suggest a likely source, and order of investigations to your doctor.
