Urine routine has occult blood how to return a responsibility

1. Excessive strenuous exercise

If the patient has excessive strenuous exercise in the near future, it will cause muscle tremors and vascular damage, and there will be blood in the urine, so urine routine examination can find occult blood.

2. Urinary calculi

If the urethral calculi are large in size and sharp in edge, they may scratch the urethral mucosa, causing blood to flow out into the urine. When conducting urine routine examination, the result is occult blood.

3. Acute glomerulonephritis

Acute glomerulonephritis will destroy glomerular filtration function, resulting in more red blood cells leaking into the urine, so urine routine examination can show occult blood.
