Why Is This Test Done?

Your healthcare provider may order this test to check for conditions like malnutrition, kidney disease, liver problems, or infections. It can also help monitor long-term health in people with chronic illnesses.

What to Expect Before the Test

No special preparation is needed. You may have a small needle inserted into your arm or vein to draw blood. If you’re on blood thinners, let your provider know before the test.

What to Expect During the Test

The blood sample will be sent to a lab for analysis. Results are typically ready within a few days, depending on your lab.

Possible Results and Their Meaning

Low albumin levels may indicate problems like kidney disease, liver failure, or severe infections. High levels could suggest dehydration or certain genetic conditions. Your provider will discuss the results in the context of your overall health.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Albumin is vital for transporting nutrients, maintaining blood pressure, and supporting immune responses. Abnormal levels can signal underlying health issues that require further evaluation, such as chronic diseases or nutritional deficiencies.

Frequently asked questions

What causes low albumin levels?
Low albumin can result from conditions like kidney disease, liver problems, malnutrition, or severe infections. It may also occur due to excessive protein loss (e.g., from kidney disease) or rapid weight loss.
What causes high albumin levels?
High albumin is less common but may occur with dehydration, certain genetic disorders, or in people who have lost fluid from the body (e.g., through vomiting or diarrhea). It’s usually not a cause for concern unless related to an underlying condition.
How often should I get this test?
Your provider will determine how often to check albumin levels based on your health needs. Regular monitoring may be needed if you have chronic conditions like kidney disease or liver problems.
