What does a positive urine occult blood test indicate?
Disease description:
I have recently experienced urgency and frequency of urination, so I underwent an examination, which revealed a positive result for occult blood in my urine. I would like to ask, what could cause a positive occult blood test in urine?

A positive urine occult blood test indicates the presence of red blood cells in the urine and may be caused by various factors, mainly including:
1. **Urinary system diseases**: Such as kidney diseases (renal tuberculosis, kidney stones, renal abscess, etc.), ureteral stones, ureteral tumors, bladder stones, and other conditions that may cause bleeding in the urinary system, leading to a positive urine occult blood test.
2. **Infectious diseases**: Such as malaria, yellow fever, typhoid fever, and other diseases that may be accompanied by urinary system damage or bleeding.
3. **Hematologic disorders**: Such as thrombotic thrombocytopenic purpura, favism, hemolytic anemia, paroxysmal cold hemoglobinuria, and other conditions that may lead to increased red blood cell destruction or abnormal coagulation function.
4. **Non-pathological factors**: Such as drug effects, testing-related factors, trauma, extensive burns, etc.
If you have any concerns, it is recommended to seek medical attention promptly.
