Why Is This Test Done?

Doctors may order albumin tests to evaluate how well your body is absorbing nutrients, especially if you have conditions like malnutrition, kidney disease, or liver disorders. It can also help monitor treatment progress for certain conditions, such as chronic kidney disease or inflammatory disorders.

What Does a Low or High Albumin Level Mean?

Low albumin levels may indicate poor nutrition, liver disease, kidney problems, or severe infections. High levels could suggest dehydration or certain medical conditions, though this is less common. Your results will be compared to a reference range specific to your lab and health profile.

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 amount of albumin protein in your blood.

What Are Common Causes of Abnormal Results?

Abnormal albumin levels can result from conditions like malnutrition, chronic kidney disease, liver cirrhosis, severe infections, or inflammatory diseases. Medications, pregnancy, or certain medical treatments may also affect albumin levels.
