serum albumin test

Albumin is a protein made by the liver. It is a transparent liquid portion of blood or urine. A test is performed to measure the proteins in it. This test is known as the Serum albumin test. 

How is the test performed? 

To perform the test, a blood or urine sample is needed.

How should you Prepare for the test? 

Your doctor might restrict you or temporarily ask you to stop consuming some medicine that affects the test. The medications which can increase albumin levels are 

  • Anabolic steroids
  • Androgens
  • Growth hormone
  • Insulin

You should not stop your medicines without consulting your doctor. 

How does the test feel?

A needle is inserted into the arm’s veins to draw blood. People may feel moderate pain or a slight prick.  Later it might start throbbing or leave a little bruise, which goes away quickly. 

Why is this test performed?

Albumin helps move small molecules like bilirubin, progesterone, calcium, and medicines through the blood. The Albumin is very important to retain the fluid in the blood and not leak into the tissues. Albumin also keeps the vitamins, hormones, enzymes, and substances flowing in your body. Your doctor will ask you to get this test when they suspect a liver or kidney disease. 

The test is performed to check if your body has enough protein or not and check for any liver or kidney disease.  

Normal results 

The range of your albumin from 3.4 to 5.4 g/dL or 35 to 54 g/L is considered normal. 

The results of the test may vary from one lab to another. You can consult your doctor to assess your result.
