Albumin in Serum (Mass Concentration)

What Albumin Does in Your Body

Albumin is one of the most abundant proteins in your blood. It plays a critical role in transporting nutrients, hormones, and medications, as well as helping maintain proper fluid balance between your blood vessels and tissues. Low albumin levels may suggest problems like liver disease, kidney issues, or severe infections.

Why It’s Tested

Doctors may order albumin tests to check for conditions affecting protein production, fluid balance, or kidney function. It’s often part of a broader evaluation for chronic illnesses like heart failure, cirrhosis, or malnutrition.

What Normal Results Mean

While specific reference ranges vary by lab, healthy albumin levels typically reflect adequate protein synthesis and kidney function. Abnormally low or high levels may signal underlying health concerns that need further investigation.

Common Conditions Linked to Albumin Levels

Low albumin is often seen in conditions like cirrhosis (liver disease), kidney failure, or severe infections. High levels may occur in dehydration or certain inflammatory states, though this is less common.
