Urine occult blood 2+ in children means that red blood cells or hemoglobin may be present in the urine of that child, which may be related to genitourinary diseases, bleeding disorders, hemolytic diseases and so on. 1. Increased red blood cells in urine: urinary occult blood is usually measured by the amount of red blood cells and hemoglobin in the urine. If red blood cells are found in the urine by microscopic examination, red blood cells are present in the urine, which may be related to urinary system inflammation such as cystitis and urethritis, urethral injuries, urinary tract stones, hemorrhagic diseases and other disorders, which lead to the entry of blood into the urine, resulting in urinary occult blood 2+. In addition, because hemophilia is an abnormality of the body’s coagulation factors, resulting in the inability to normal coagulation, which can lead to bleeding, so children’s urinary occult blood 2 + may be related to hemophilia and other bleeding disorders, etc., and transient hematuria can also occur after strenuous exercise in healthy people. 2. Increased hemoglobin in urine: when there is increased hemoglobin in urine, red blood cells will not be found on microscopic examination, but there will also be urinary occult blood 2+, which may be related to paroxysmal sleep hemoglobinuria, blood group incompatibility, immune hemolytic anemia and other causes of hemolysis, resulting in increased hemoglobin in the blood. When children have urinary occult blood 2+, they actively go to a specialized hospital, and need to clarify the cause of the disease under the guidance of a specialist and actively treat it.
