Urine occult blood is often found to be positive in urine routine. How to treat the introduction of its significance;

Concealed blood, that is, invisible blood, is often detected by chemical methods when red blood cells are destroyed.

Urinary occult blood allows hemoglobin in red blood cells to release oxygen under the catalysis of peroxide.

O-diphenylmethylamine generates blue compounds under the action of oxygen, while some oxidants such as hypochlorous acid

Peroxidase in microorganisms can make urine occult blood positive.

There is occult blood positive in urine, how to distinguish whether it is true bleeding. Let's analyze:

1) since it is bleeding, it is mostly caused by inflammatory stones and tumors, and it is caused by vascular destruction.

Or the diameter of blood vessels increases, not only red blood cells will leak out, but also protein in plasma will leak out.

Protein qualitative will also appear different degrees of positive, there are red blood cells under the microscope. The color of urine is red.

2) When the amount of bleeding is small, the urine protein is normal qualitatively, and red blood cells are destroyed by acid and alkali substances in urine.

If the microscope can't find red blood cells, you can pass many urine tests or urine sediment tests.

Whether there are "red blood cells" or not. A large amount of hemolysis can cause urine color change, and the urine color is brown or strong tea color.

3) Urine occult blood alone, no "red blood cells" under microscope, and no symptoms. Under normal circumstances, urine color belongs to oxide interference.

There is no need to worry about causing false positives.
