Your Albumin is
Kidney disease can result in abnormal albumin levels because diseased or damaged kidneys are not able to effectively filter out and recycle albumin in the blood; instead, albumin leaks into the urine.
Proteins are normally filtered out of the blood by the kidneys and recycled in the body. When kidneys are diseased or damaged, however, their ability to filter out proteins is compromised, which allows protein to then leak into urine.
The serum is the clear, liquid portion of the blood. There are two classes of proteins, albumin and globulin, found in the blood. Albumin is the most abundant protein; its main purpose is to keep fluid from leaking out of blood vessels.
