Urine occult blood (++) is usually not considered serious. Urine occult blood (++) is caused by urinary tract infection, urinary stones or urinary tract tumors, etc. Some differential diagnosis of these diseases is needed. It is recommended to go to the hospital in time for routine urine, urine culture and urinary ultrasound to make a preliminary judgment. If the urine routine is only positive for urine occult blood and not for white blood cells, and the urinary ultrasound does not reveal any urinary stones or urinary tumors, simple urine occult blood is generally not a big problem and will not pose a greater danger to the body. It is recommended to drink more water and pay attention to rest to improve the situation.
