Why Is This Test Done?

Your healthcare provider may order this test to check for conditions like kidney disease, liver problems, malnutrition, or dehydration. It can also help monitor protein loss due to certain medical conditions or treatments.

What Does a Result Mean?

Higher-than-normal results might suggest conditions like liver disease, severe dehydration, or overhydration. Lower-than-normal results could indicate malnutrition, kidney disease, or protein loss from the body.

Common Conditions Monitored

This test is often used to monitor kidney function, detect liver issues, and evaluate nutritional status. It may also be part of a broader evaluation for conditions affecting protein synthesis or retention.

Sample Collection and Preparation

A blood sample is drawn from a vein, usually in your arm. The blood is then processed to separate serum or plasma for testing. This test does not require fasting.
