Why Is This Test Done?

Your healthcare provider may order this test to check for conditions like kidney disease, malnutrition, liver problems, or to monitor treatment effectiveness. Low albumin levels can indicate fluid retention, swelling, or poor nutrient absorption.

What to Expect Before the Test

No special preparation is needed. You’ll have a small needle inserted into a vein (usually in your arm) to draw a blood sample. The process is quick and typically painless.

What the Results Mean

Results are compared to a general reference range for healthy adults. Very low levels may signal kidney issues, liver disease, or severe dehydration, while very high levels could suggest dehydration or chronic disease.

Common Conditions Monitored

This test is often used to monitor kidney function, especially in patients with chronic kidney disease, or to evaluate protein loss in urine (e.g., nephrotic syndrome). It can also help diagnose malnutrition or liver disorders.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
