Why Is This Test Done?

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

What Does a Low or High Level Mean?

Low albumin levels might suggest problems with your kidneys, liver, or malnutrition. High levels could be due to dehydration or certain medical treatments.

How Is the Test Performed?

A blood sample is taken from a vein, usually in your arm. The blood is then sent to a lab to measure albumin concentration using a standard laboratory method.

What Are Common Causes?

Conditions like kidney disease, liver disease, severe infections, or poor nutrition can affect albumin levels. Certain medications or medical treatments may also play a role.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Albumin is a key protein in the blood that helps maintain proper fluid balance and supports immune function. Low albumin levels can signal underlying health issues, such as kidney or liver dysfunction, malnutrition, or chronic infections. High levels may indicate dehydration or specific medical conditions. Regular monitoring of albumin can help track overall health, especially in people with chronic illnesses.
