Why Albumin Matters in Your Health

Albumin plays a key role in transporting nutrients, hormones, and medications throughout your body. It also helps regulate blood pressure by controlling fluid movement between your blood vessels and tissues. Low albumin levels can sometimes be a sign of problems like chronic kidney disease, liver disease, or severe infections.

What Causes Albumin Levels to Change?

Several factors can affect albumin levels, including diet (low protein intake), certain medications, kidney or liver disease, infections, or conditions like burns or severe illness. Some people may also have inherited disorders that affect protein production.

When Might You Need This Test?

Your doctor may order an albumin test to check for health issues like malnutrition, kidney disease, liver disease, or to monitor conditions such as heart failure, severe infections, or after surgery.

What to Expect During the Test

This test is usually done by drawing blood from a vein in your arm. You may feel a small pinch, but it’s quick and painless. No special preparation is needed unless your doctor instructs otherwise.
