Blood or protein in Urine

[magic315]

Why is the presence of blood or protein in urine considered abnormal?

[Dr.Stein]

Because urine is a product of excretory system. Blood and protein should not be in the urine because we need them and must not excrete them out.

The presence of blood and urine as an indication of broken filtration of kidney function, to be precise in Malpighian body part.

[Darby]

Protein indicates filter damage - they should be too big to fit through, unless the holes are opened by damage. This often indicates an infection in the body, since "engorged" white blood cells often catch on thew filters, die, and their released digestive enzymes damage the filters.

Blood should never go through the filters, even damaged ones. Red blood cells are indications of bleeding in the urinary system. The most common cause here is kidney stones. Infections in the system that ulcerate will release RBCs, too, but then there will also be white blood cells in the urine.

why should there be blood in your urine?

[Dr.Stein]

Urine is made from filtered blood. If you have blood in your urine, it means that there is something wrong with the filter. Blood should not be in urine.
