Serum or plasma concentration of albumin (mass concentration)

Published: August 9, 2026Updated: August 16, 2026

This test measures the amount of albumin, a protein found in your blood, which helps maintain fluid balance and supports immune function. Low levels may indicate kidney disease or malnutrition, while high levels could suggest dehydration or liver conditions.

Why Is This Test Done?

Your healthcare provider may order this test to check for conditions like kidney disease, liver problems, malnutrition, or dehydration. It can also help monitor protein loss due to conditions such as nephrotic syndrome or chronic kidney disease.

What Does a Low or High Albumin Level Mean?

Low albumin levels might signal poor nutrition, kidney issues, or inflammation. High levels could indicate dehydration or certain liver disorders. Your results will be compared to standard reference ranges specific to your age and health status.

How Is This Test Performed?

A blood sample is drawn from a vein, usually in your arm. The blood is then processed to separate serum or plasma for testing. The test measures the protein concentration using an immunoassay method, which detects albumin specifically.

What Are Common Causes of Abnormal Results?

Abnormal albumin levels can result from dietary deficiencies, severe infections, burns, or chronic diseases like kidney failure or cirrhosis. Other factors, such as fluid shifts or certain medications, may also affect results.

Frequently asked questions

How often should I expect this test as part of routine check-ups?
The frequency depends on your health status. Routine adults may not need this test unless they have risk factors like kidney disease, liver issues, or malnutrition. Follow-up testing may be recommended if you have a chronic condition or symptoms like swelling, weight loss, or fatigue.
What should I do if my albumin level is outside the normal range?
If your results are abnormal, discuss them with your healthcare provider. They may recommend further testing, adjustments to your diet, or treatment plans to address underlying causes, such as improving protein intake or managing kidney/liver conditions.
Can diet or lifestyle changes affect albumin levels?
Yes, diet plays a role. Eating enough protein and staying hydrated can help maintain normal albumin levels. Avoiding excessive alcohol and managing chronic conditions like diabetes or kidney disease can also support stable results.
