Albumin Blood Test - (2023)

About the Test

Purpose of the test

The purpose of the test is to evaluate whether you have abnormal levels of albumin in your blood. Levels that are too high or too low can indicate an underlying health problem. Testing for albumin alone or with other measurements can play a role in diagnosing, screening, and monitoring different conditions.

Diagnosis is testing that happens after symptoms have occurred. For example, a doctor may recommend an albumin blood test if you have signs of potential liver disease like jaundice, fatigue, or symptoms of possible kidney disease, such as abnormal urination or unexplained swelling (particularly of the feet and legs).

Screening is a form of testing that tries to identify health conditions before symptoms arise. It is not usually done by measuring albumin alone. Still, albumin may be included with other measurements in a comprehensive metabolic panel or liver panel that may be prescribed during a routine medical check-up as a form of screening.

Monitoring involves testing to see how your condition develops or responds to treatment. Follow-up tests for albumin in the blood may provide information about the severity of the disease and how a condition changes over time.

What does the test measure?

The test measures the total amount of albumin in the blood. Albumin’s biological functions are to keep fluid from leaking out of the blood vessels and to carry substances like hormones, enzymes, and vitamins in the body.

If albumin is included in a panel test, other measurements will be taken using the same blood sample.

When should I get an albumin test?

An albumin blood test may be ordered if you have symptoms that could be caused by a problem affecting your liver or kidneys. Albumin levels alone do not diagnose these types of conditions, but they can provide important information to help your doctor identify the problem.

If you don’t have any signs of liver or kidney problems, it is not typically recommended to test for albumin alone. However, an albumin measurement may be included in panel tests that may be used for medical check-ups. In these tests, like the comprehensive metabolic panel, albumin levels can be interpreted in relation to other measurements.

Your physician can best explain whether and when an albumin blood test is recommended in your specific situation.

Finding an Albumin Blood Test

How can I get an albumin blood test?

An albumin blood test requires a blood sample from a vein in your arm. A health professional typically prescribes the test, and the sample is taken in a doctor’s office, health clinic, hospital, or laboratory.

Can I take the test at home?

Blood tests to measure albumin levels alone are not currently available as an at-home test. Panel tests that include albumin are normally done in a medical setting, but some at-home options exist to measure albumin along with other indicators of liver function. These tests involve collecting a drop of blood from your fingertip, applying it to a test strip, and sending the sample by mail to a laboratory where it can be analyzed.

How much does the test cost?

The cost of an albumin blood test depends on multiple factors, including where you have the test taken, whether other measurements are included, and whether you have medical insurance.

The testing costs may include an office visit, the technician fee for drawing your blood, and the laboratory fee for analyzing your sample. Insurance often covers these costs when your physician prescribes the test. Still, check with your insurance plan for coverage details, including whether you are responsible for a deductible or copay.

Taking an Albumin Blood Test

Testing requires a blood sample that is normally obtained by removing a small amount of blood from a vein in your arm. This blood sample can be taken in a doctor’s office or another medical setting.

While at-home tests are far less common, they can be done by pricking your finger to get a drop of blood that can be sent to a lab.

Before the test

Before taking an albumin blood test, tell your doctor about any medications or supplements you are taking. Some types of drugs can affect albumin levels, and your doctor can tell you if it is necessary to adjust your medications before the test.

If only albumin is being measured, you do not need to fast before your blood is drawn. When albumin is measured as part of a panel test, you may need to avoid eating or drinking any beverages besides water for 12 hours or more beforehand.

Check with your physician ahead of time to find out exactly which test you are having and any required preparation. If the doctor mentions any test preparation, follow those instructions carefully.

With at-home tests, it is essential to carefully read all the instructions before taking the test to ensure that you prepare your sample correctly.

During the test

The test procedure involves removing a small vial of blood from a vein in your arm. You will sit in a chair, and an elastic band will be tied around your upper arm. An antiseptic is used to clean the inside of your arm near your elbow, and a needle will be inserted to withdraw blood.

The entire process normally lasts less than a couple of minutes. There may be minor pain or discomfort when the needle is inserted and removed.

An at-home test kit involves a quick fingerstick to obtain a drop of blood from your fingertip. The blood sample is placed on a strip of test paper and then packaged for delivery to a laboratory.

After the test

A bandage or cotton swab may be used to apply pressure and stop bleeding after your blood has been drawn. There may be light bruising or soreness around the puncture site. You can usually drive and return to normal activities after the test.

A blood draw is a routine procedure with no serious or lasting side effects. Contact your doctor for specific guidance if you notice any severe or persistent effects.

There are few lasting effects after an at-home test with a fingerstick. If your fingertip keeps bleeding after taking the test sample, you can apply pressure with a cotton swab or a bandage.

Albumin Blood Test Results

Receiving test results

Results from an albumin blood test are usually available within a few business days. Your doctor’s office may contact you directly to provide your results, or you may get a test report sent to you electronically or in the mail.

Interpreting test results

Your test report will list your albumin level. Albumin is measured in grams per deciliter (g/dL) of blood. If other measurements were taken in a panel test, you would see separate line items for each of those measurements on your test report.

A typical reference range for normal albumin levels is 3.5 to 5.5 g/dL. Reference ranges can vary by laboratory, so it is important to look closely at your test report to see if a different range is listed.

Albumin levels above or below the reference range may reflect an underlying health concern. Low levels can be caused by conditions that affect the liver’s normal function and ability to synthesize albumin or excessive loss of albumin through the kidneys.

Albumin persists in the blood for several weeks, so recent, short-term liver health issues that decrease albumin production may not be detected. Decreased albumin levels are more frequently associated with chronic conditions affecting the liver, like cirrhosis.

Although albumin is produced in the liver, abnormally low levels can also be tied to kidney conditions, malnutrition, inflammation, infection, thyroid disease, and gastrointestinal problems. Abnormally high albumin levels most often occur due to dehydration, which may be caused by other conditions such as severe diarrhea.

Doctors often interpret the significance of albumin levels alongside measurements of other indicators of metabolism and the health of the liver and kidneys. Seeing which measurements are normal and abnormal can help reveal patterns in your results that may reveal the most likely cause of the test’s findings.

Your physician is best able to describe your test results and review what they may mean for your health, as well as whether any other tests are appropriate as a follow-up.

As you review your test results with your physician, some of the following questions may help you better understand your situation and the significance of your albumin level:

  • Was my albumin level normal or abnormal? If it was abnormal, was it high or low?
  • Were any other measurements taken along with albumin? What can you learn from those levels?
  • What is the most likely explanation for my test result?
  • Are there any follow-up tests that you recommend? What are the pros and cons of those tests?

What does a albumin blood test check for? ›

This test measures the amount of the protein albumin in your blood. Your liver makes albumin. Albumin carries substances such as hormones, medicines, and enzymes throughout your body. This test can help diagnose, evaluate, and watch kidney and liver conditions.

What is the normal range for albumin blood test? ›

Normal Results

The normal range is 3.4 to 5.4 g/dL (34 to 54 g/L). Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your provider about the meaning of your specific test results.

What does elevated albumin in the blood mean? ›

An albumin blood test checks your liver and kidney function. Albumin is protein in your blood plasma. Low albumin levels might be the result of kidney disease, liver disease, inflammation or infections. High albumin levels are usually the result of dehydration or severe diarrhea.

What level of albumin creatinine indicates kidney failure? ›

What does the uACR test result mean? A normal amount of albumin in your urine is less than 30 mg/g. Anything above 30 mg/g may mean you have kidney disease, even if your estimated glomerular filtration (eGFR) number is above 60.

Why would a doctor order an albumin test? ›

An albumin blood test is used to check your general health and to see how well your liver and kidneys are working. If your liver is damaged or you're not well nourished, your liver may not make enough albumin. If your kidneys are damaged, they may let too much albumin leave your body in urine (pee).

What would happen if a person had a low level of albumin in their blood? ›

When albumin levels are low, the blood may not be able to transport essential materials, such as hormones, effectively. This can lead to a range of symptoms, including fatigue, jaundice, and fluid retention. Albumin binds substances, including hormones and some drugs, to help them travel through the body.

What level of albumin indicates liver failure? ›

The most common reason for a low albumin is chronic liver failure caused by cirrhosis. The serum albumin concentration is usually normal in chronic liver disease until cirrhosis and significant liver damage has occurred. In advanced liver disease, the serum albumin level may be less than 3.5 g/dl.

How do you fix albumin levels? ›

Taking vitamins (vitamin D) and eating a well-balanced diet full of protein like lean meats, fish, nuts (almonds, cashews, walnuts, etc.) and eggs, along with dairy products (milk, yogurt, cheese) and whole-grain carbohydrates (bread and rice) can increase the amount of albumin your body produces.

Although very small amounts of protein in urine can be normal, high levels of albumin is one of several indicators of chronic kidney disease (CKD), a common complication of both type 1 and type 2 diabetes.

Does high albumin always mean kidney disease? ›

Having albumin in your urine can be a sign of kidney disease, even if your estimated glomerular filtration rate (eGFR) is above 60 or “normal”. Albuminuria (proteinuria) is not a separate disease. It is a symptom of many different types of kidney disease and a significant risk factor for complications.

What should you avoid if your albumin is high? ›

Use fresh meat products and avoid pre-made roasted chicken and other processed meats, which often contain large amounts of sodium and phosphorus. This excess sodium and phosphorus isn't good for patients with chronic kidney disease.

  • tiredness.
  • blood in your pee (urine)
  • an increased need to pee – particularly at night.
  • difficulty sleeping (insomnia)
  • itchy skin.

What color is urine when your kidneys are failing? ›

When your kidneys are failing, a high concentration and accumulation of substances lead to brown, red, or purple urine. Studies suggest the urine color is due to abnormal protein or sugar as well as high numbers of cellular casts and red and white blood cells.

What medications can cause high albumin creatinine ratio? ›

  • Angiotensin-converting enzyme inhibitors (ACE inhibitors like lisinopril)
  • Angiotensin II receptor blockers (ARBs like losartan)
  • Other blood pressure medications.
  • Medications for diabetes if needed (like metformin)8.
