If urine occult blood is weak positive, it should also be combined with ultrasound and blood test to determine whether treatment is needed. If there is no other abnormality, it is considered that the urine specimen has been placed for too long, or the blood is mixed into the specimen, resulting in false positives, or physiological hematuria caused by strenuous exercise, which generally does not require special treatment. If urinary occult blood is weakly positive for other tests suggesting the presence of urinary tumors, stones or inflammation, should be promptly carried out the appropriate surgical resection, extracorporeal shock wave lithotripsy or anti-infection treatment.
