What Albumin Does in Your Body

Albumin is produced by your liver and plays several important roles. It helps distribute nutrients, maintains blood pressure, and carries hormones and medications through your bloodstream. Low levels may indicate problems like liver disease, kidney issues, or malnutrition.

Why It’s Tested

Doctors may order this test to check for conditions affecting protein levels, such as kidney disease, liver problems, or severe infections. It can also help monitor treatment responses in certain medical situations.

How the Test Works

A blood sample is taken, and the albumin protein is measured using a specialized lab technique that detects its concentration in your serum or plasma.

What to Expect Before the Test

No special preparation is needed, but you may want to avoid heavy meals 2 hours before the draw. Wear comfortable clothing if you need an arm restraint.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What might cause low albumin levels?
Low albumin can result from liver disease (like cirrhosis), kidney problems, malnutrition, severe infections, or burns. High albumin may suggest dehydration or overproduction in rare cases, but this is less common.
How long does it take to get results?
Results are typically available within 1–3 business days, depending on your lab. Follow up with your provider if you have questions about the outcome.
Can diet affect albumin levels?
Yes—poor nutrition (low protein intake) can lower albumin, while balanced diets support normal levels. Your doctor may recommend dietary adjustments if needed.
