Albumin Test

Albumin is an important, most abundant protein produced by the liver. It circulates in the blood and helps maintain fluid balance in the body by preventing fluid from leaking out of the blood vessels. It also helps transport vitamins, hormones, and certain medications throughout the body.

The Albumin test, also known as the serum albumin test, helps to assess nutritional status, overall health, and evaluate liver diseases and chronic illnesses. It is performed alone or as part of wider test panels, such as liver function tests, comprehensive metabolic panels, or total protein tests.

Albumin testing is usually performed as part of a routine health check-up or is recommended to assess liver and kidney function.

A doctor may recommend this test to people with:

• Heart disease or hypertension
• Diabetes
• Liver disease
• Chronic kidney disease 
• Burns or injuries
• Pre or post surgery
• Pregnant women

This test is usually recommended for the following symptoms:

• Unexplained weight loss 
• Loss of appetite
• Fatigue or weakness
• Jaundice - yellowish discolouration of skin or eyes
• Presence of swelling in legs, feet, abdomen, or puffy eyes
• Foamy or frothy urine
• Slow wound healing

The Albumin test helps evaluate various conditions, such as:

• Liver disease - Lower albumin levels help detect the presence of liver cirrhosis, jaundice, hepatitis, and ascites.
• Kidney disease - Lower levels of albumin in the body may indicate leaking of albumin into urine due to chronic kidney disease.
• Inflammation - Chronic inflammation in the body due to infection, burns, or surgery lowers albumin levels. Also helps detect chronic inflammatory conditions like rheumatoid arthritis, systemic lupus erythematosus [SLE].
• Celiac disease - An autoimmune condition due to gluten allergy that causes damage to the small intestine.
• Crohn’s disease - A chronic condition causing inflammation of the digestive tract.
• Ulcerative colitis - A chronic inflammatory condition of the large intestine leading to the development of small ulcers in the large intestine.
• Whipple disease - A chronic disorder that impairs digestion and nutrient absorption in the body.
• Malnutrition - Low albumin protein levels indicate malnutrition.
• Dehydration - High albumin levels are suggestive of severe dehydration.
• Thyroid disorders - Low albumin levels may indicate thyroid disorders.

What to Expect Before the Albumin Test

• No special preparation is usually needed before the test. However, if this test is performed as part of a wider test panel, fasting or avoiding certain foods or medications may be required. Consult your doctor before the test for any special instructions.

What to Expect During the Blood Sample Collection

During blood sample collection from the inner arm, you can expect the following: 

1. An elastic band is tied around your arm for better visibility of veins.
2. A needle is inserted into a vein of the inner arm. You may feel a slight pinch.
3. Blood is collected in a test tube for lab testing.

What to Expect After the Albumin Test

• This blood sample collection procedure is generally safe with little to no risks.
• Feeling dizzy for a few seconds is common and improves with a little rest.
• Any minor bleeding is usually controlled with a bandage.
• However, if you notice anything unusual, such as bleeding, pain, or a rash at the puncture site, contact your healthcare provider.

The Albumin test measures a single parameter, given below:

Serum albumin: This test measures the levels of albumin protein in blood.

If performed as a part of a wider panel, such as a liver function test or total protein test, it may include parameters like enzymes or other proteins made by the liver.

Albumin levels are usually reported in grams per decilitre.

Important note: The normal values of the test parameter may vary from lab to lab. Please refer to the ranges mentioned in your report and consult your doctor to understand what the levels indicate for your body.

Note: This table is for educational purposes only. It does not confirm a diagnosis. Many factors, such as age, gender, diet, family history, and current medications, can affect these levels. Always consult your doctor to understand how these results relate to your symptoms and overall health.

Potential Risks and Complications

• Performing the serum albumin test is generally safe with minimal to no risks.
•  If you experience any bleeding, pain, or a rash after sample collection, contact your healthcare provider.
•  Feeling dizzy or lightheaded for a few seconds is common and usually improves with a little rest.

Understanding Albumin Test Limitations

• The Albumin test helps detect levels of albumin in blood, but does not confirm the diagnosis of a specific disease.
• Albumin levels are easily affected by hydration status, nutrition, or fasting. 
• During pregnancy or post-surgery, low albumin levels are usually observed. 
• A doctor’s guidance is important for the correct interpretation of test results.

If serum albumin levels are low, the doctor may recommend follow-up tests such as:

1. Liver function tests - to assess liver conditions like cirrhosis, hepatitis, or jaundice.
2. Renal/kidney function tests - to assess kidney-related conditions leading to low albumin levels.
3. Inflammatory markers test, such as CRP [C-reactive protein] or ESR [erythrocyte sedimentation rate]- to check for any underlying infection causing inflammation.
4. Complete blood count (CBC)
5. Vitamin levels tests, such as vitamin B12, vitamin D, and folate, or iron studies - to assess if malnutrition or intestinal issues are suspected. 
6. CT scan or ultrasound - for abdominal imaging to assess liver and kidney structure.
