Other names: proteinuria, mikroproteinúrie, albuminuria

The presence of protein in the urine (proteinuria) is no longer detectable landmark paper of the urine for example. GP surgeries. Not always it is a pathological symptom. While searching for the cause is often important to know not only how the large amount of the protein occurs, but also what kind of protein it is.

Blood contains a relatively large amount of protein in the body perform different functions. Kidneys in its many tělískách (glomeruli) filtered blood in primary urine so that large molecules (such as just protein) in the urine almost do not transfer.

Roughly speaking, the change of proteins in the urine may be due to three separate systems:

First, it increased the amount of protein in the blood (increased supply of protein “before kidney”), eg. Fever, after physical exertion or increased protein intake diet.

Secondly, there may be a fault in the glomeruli filter barrier that can not transfer protein prevent (diabetes, high blood pressure and inflammation of the kidneys), or a disorder of renal tubules, which normally accidentally filtered protein in urine absorbed back.

Third, you can think of to direct transmission of blood plasma proteins directly into the urinary tract because of their inflammation, bleeding disorders or cancer.

The doctor depending on the nature of proteinuria and other symptoms to determine whether they need further detailed examination.
