Albumin

The Albumin test measures the level of albumin, a protein produced by the liver, in your blood. Albumin plays a key role in maintaining blood volume and pressure by helping to keep fluid from leaking out of blood vessels. It also transports hormones, vitamins, and drugs throughout the body. This test is commonly used to assess liver function, kidney health, and nutritional status.

Why consider this test?

This test is important for detecting conditions related to the liver, kidneys, and nutritional deficiencies. Low albumin levels may indicate liver disease, kidney disease (such as nephrotic syndrome), malnutrition, or chronic inflammation. Monitoring albumin levels can also help track the progression of these conditions and guide treatment decisions. If you're experiencing symptoms like swelling (edema), fatigue, or unexpected weight changes, an albumin test can help your healthcare provider determine the underlying cause.

Who should get this test done?

Individuals who may benefit from the Albumin test include:

• Those with symptoms of liver disease (such as jaundice, abdominal pain, or swelling).
• People with kidney conditions, especially those with edema or protein in the urine
• Individuals with malnutrition or those at risk for nutritional deficiencies
• People with chronic inflammation, such as in autoimmune conditions or infections
• Patients undergoing treatment for conditions that may affect albumin levels (such as liver or kidney disease)
• Individuals being monitored for conditions like heart failure or diabetes, where albumin levels can be affected

More Information

The Albumin test is typically done as part of a comprehensive metabolic panel or liver function test. While the test measures albumin in your blood, it is often used in combination with other tests to provide a more complete picture of your health, especially liver and kidney function.

Normal albumin levels are essential for maintaining fluid balance in your body and for ensuring proper transport of substances within the bloodstream. Low albumin levels can be a sign of liver disease (e.g., cirrhosis or hepatitis), kidney disease (especially nephrotic syndrome), or inadequate protein intake. In some cases, high albumin levels may indicate dehydration, as the blood becomes more concentrated.
