R77.0: Abnormality of albumin

The amount of certain proteins in your blood has changed.

Tests have shown that the amount of certain proteins in your blood has changed. These proteins are also called albumins. All these proteins are produced in the liver. Certain substances such as messenger substances or drugs bind to the albumins. These substances can be carried through the albumins in the blood.

If the amount of albumins in the blood has changed, this can be an indication of liver or kidney disease, for example. You may also not get enough protein with your food. If you get too little protein with your food, then not enough albumin is produced.
