Serum or Plasma Albumin Concentration (Electrochemiluminescence Immunoassay)

What Albumin Does in Your Body

Albumin is a vital protein produced by your liver. It plays a critical role in transporting nutrients, maintaining blood pressure, and supporting the immune system. Low levels can indicate liver disease, kidney problems, or malnutrition, while high levels may suggest dehydration or certain medical conditions.

Why It’s Tested

Doctors may order albumin tests to check for liver function, kidney health, or nutritional status. It’s often included in routine blood work or when evaluating symptoms like swelling (edema), fatigue, or unexplained weight loss.

Common Reasons for Testing

Albumin testing is commonly done when symptoms suggest liver disease (e.g., jaundice, fatigue), kidney issues (e.g., swelling, poor urine output), or poor nutrition. It may also be checked before surgeries to assess fluid balance or during pregnancy to monitor protein needs.

What to Expect Before the Test

No special preparation is needed, but you may be asked to fast for 8–12 hours before the test if it’s part of a broader liver or kidney panel. Bring any medications or supplements you’re taking, as they may affect results.
