Doctor's answer:
Urine occult blood refers to the presence of an increased number of red blood cells in a routine urinalysis. In a minority of cases, it can be referred to as occult blood in the urine. In the urinalysis report, the urine red blood cell count is indicated with a " " or "-" symbol. Under normal red blood cell levels, the urine red blood cell column typically shows a negative result, denoted by a "-" sign. When there is an increase in red blood cells, indicating the presence of occult blood in the urine, it is considered a positive result for occult blood.
