What does the urine occult blood+-mean in the physical examination report?

1. Urine occult blood+-. It means that urine occult blood (BLD) is positive, which only means that urine contains red blood cells, which are not the intact red blood cells actually seen under the microscope, but the red blood cell components detected by the computer. Normal people's red blood cells are constantly destroyed and their components are excreted from urine, so some normal people's urine will also be positive for occult blood. Therefore, hematuria can only be diagnosed when the red blood cells in the urine are greater than 3 /HP under the microscope.

2. it doesn't matter. Drink plenty of water and check for a week or so. If it still exists, you can use a microscope to check whether there are red blood cells in the urine. If not, that's normal.
