What is the presence of protein albumin in urine and a sign impaired kidney function?

Albumin is a protein that is normally present in the blood. However, when the kidneys are not functioning properly, albumin can leak into the urine. This is called albuminuria or proteinuria.

Albuminuria can be a sign of several kidney diseases, including:

* Diabetic kidney disease

* Glomerulonephritis

* Polycystic kidney disease

* Kidney failure

Other conditions, such as high blood pressure and heart failure, can also cause albuminuria.

The presence of albumin in the urine is usually detected through a urinalysis. A urinalysis is a test that examines the physical, chemical, and microscopic properties of urine.

If you have albuminuria, your doctor may recommend further tests to determine the cause. Treatment will depend on the underlying cause of the albuminuria.

Early detection and treatment of kidney disease can help to prevent serious complications, such as kidney failure.
