Patient: Description (onset time, main symptoms, hospital visited, etc.): Recently, I had a routine urine test and found that the occult blood was microscopic, microscopic red blood cells 0-5, microscopic white blood cells 0, other than nothing, and three days later, I rechecked my morning urine, the occult blood was microscopic, microscopic red blood cells 0-1, microscopic white blood cells 0-1, the kidney ultrasound was normal, and I did a urine red blood cell bitmap, the results: total red blood cells 1500/mL, orthotypic red blood cells 0. In the last two years, the urine routine examination is occult blood trace, other indicators are normal, no physical discomfort, no family genetic hematuria No. What is the disease? How to treat? Hospital Pediatrics: Hello! According to your information, it is not yet possible to say that your child’s routine urine examination is abnormal. The reason is as follows: 1, the diagnostic criteria for hematuria is three consecutive urine tests, the red blood cell count in the urine is more than 8-10 red blood cells per high-powered field of view, your child did not exceed the standard 2, occult blood is used to distinguish between hemoglobinuria and hematuria, but now are instruments to make urine routine, has lost the original test significance, so only this is not enough to consider for hematuria. 3, the total number of red blood cells in the urine exceeds a certain number (such as 8000 / ml), it is necessary to check the form of red blood cells, otherwise there is no clinical significance. I hope the above will be helpful to you. Patient: My son was found to have microscopic occult blood in 2006, but I never paid attention to it, and only recently I took out the previous test sheets to see that they were all microscopic occult blood or +-, red blood cells 0-1, and other normal, so I need to check his urine regularly? How often should I test him and what should I do if he still has microscopic occult blood? Hospital Pediatrics: Hello! From your test results, it can not be said that there is the presence of hematuria, you can recheck the urine routine once in a couple of months. There is no need to worry too much.
