Serum or plasma concentration of human serum albumin (electrochemical method)

Why Albumin Matters in Your Health

Albumin plays a critical role in keeping fluids where they need to be—like in your blood vessels—rather than leaking into tissues. It also carries important substances, such as hormones and medications, around your body. Low albumin levels might suggest problems with your liver, kidneys, or malnutrition, while high levels could be due to dehydration or certain medical conditions.

What Can Affect Your Albumin Test Result?

Several factors can influence your albumin test, including recent protein-rich meals, hydration status, chronic illnesses like liver disease or kidney problems, or medications that affect protein production. If you’re unsure about recent food or fluid intake, let your healthcare provider know so they can interpret the result accurately.

Common Causes of Low or High Albumin Levels

Low albumin levels (hypoalbuminemia) are often seen in conditions like liver disease, kidney failure, severe infections, or malnutrition. High albumin levels may occur in dehydration or rare cases of overproduction, though this is less common. Your doctor will use the result alongside other tests to diagnose potential issues.

How Is This Test Performed?

This test involves drawing a small amount of blood from a vein in your arm. The blood is then processed to measure the concentration of albumin, typically using an electrochemical method. The result is usually available within a few days, depending on lab processing times.
