Published: August 9, 2026Updated: August 16, 2026

This test measures the amount of albumin, a protein found in your blood, which helps maintain fluid balance and supports immune function. Albumin levels can be checked to assess overall protein status or detect conditions like liver disease or kidney problems.

Why This Test Might Be Ordered

Your healthcare provider may order this test if you have symptoms like swelling (edema), unexplained weight loss, fatigue, or signs of liver or kidney disease. It may also be part of a routine checkup or screening for conditions affecting protein levels.

How the Test Works

Albumin is measured using electrophoresis, a method that separates proteins in your blood based on size and charge. The test looks at the total amount of albumin in your serum or plasma sample.

What to Expect Before the Test

No special preparation is usually needed, but you may be asked to fast for 8–12 hours before the test if it involves drawing blood. Avoid smoking or caffeine for 30 minutes before the draw if instructed.

What to Expect During the Test

A healthcare professional will insert a small needle into your arm to draw blood. You may feel a brief pinch, but the procedure is quick. If you experience dizziness or lightheadedness, let them know right away.

Frequently asked questions

How long does it take to get results?
Results are typically available within 1–2 business days, depending on your lab’s processing time. Follow up with your provider if you have questions about the timing of your results.
What does a low or high albumin level mean?
Low albumin levels may signal conditions like chronic liver disease, kidney problems, or poor nutrition. High levels are less common but could be linked to dehydration or specific medical conditions. Your provider will discuss these findings with you during your visit.
Can diet affect albumin levels?
Yes, diet can influence albumin levels. Eating enough protein-rich foods (like lean meats, eggs, or dairy) supports healthy albumin production. Chronic malnutrition or excessive alcohol use may lower albumin levels, so it’s important to discuss your diet with your provider if you suspect it’s affecting your health.
