What is a total protein test?

This test will also look at the ratio of albumin to globulin in your blood. This is known as the “A/G ratio.”

How is the total protein test performed?

The test uses a blood sample that’s analyzed in the laboratory. To get a blood sample, a healthcare provider will draw blood from a vein in your arm or the back of your hand. First, they’ll clean the site with an antiseptic wipe. They’ll wrap a band around your arm to apply pressure to the area and gently insert the needle into the vein. The blood will collect into a tube attached to the needle. Once the tube is full, the band and the needle will be removed from your arm. They’ll put pressure on the puncture site to stop any bleeding.

In infants or small children, a lancet is used to puncture the skin and the blood collects in a small glass pipette, test strip, or onto a slide. A bandage may be placed over the area if there’s any bleeding.

Preparing for the total protein test

You don’t need to make any special preparations before the test is done. Your doctor will let you know if you should avoid food or drinks before the test.

 Many medications can affect the total protein test results. Talk to your doctor about your current medication use before you take this test.


Medications that can affect the test results include: 

  • steroids

  • androgens  

  • corticosteroids

  • dextran

  • growth hormone

  • insulin

  • phenazopyridine

  • progesterone

  • ammonium ions

  • estrogen

  • birth control pills


Test risks

You may feel moderate pain or discomfort from the blood test. The risks associated with having a blood test are minimal. In some cases, you may experience:


  • excessive bleeding

  • fainting or feeling light-headed

  • developing a hematoma, which occurs when blood gathers under your skin

 There is a risk of infection any time your skin is broken.

What do the results mean?

Total protein range

The normal range for total protein is between 6 and 8.3 grams per deciliter (g/dL). This range may vary slightly among laboratories. These ranges are also due to other factors such as:


  • age

  • gender

  • population

  • test method


Your total protein measurement may increase during pregnancy.

If total protein is abnormal, additional tests must be performed to identify which specific protein is low or high before a diagnosis can be made.

Elevated total protein may indicate:

  •  inflammation or infections, such as viral hepatitis B or C, or HIV

  • bone marrow disorders, such as multiple myeloma or Waldenstrom’s disease


Low total protein may indicate:

  • bleeding

  • liver disorder

  • kidney disorder, such as a nephrotic disorder or glomerulonephritis

  • malnutrition

  • malabsorption conditions, such as celiac disease or inflammatory bowel disease

  • extensive burns

  • agammaglobulinemia, which is an inherited condition in which your blood doesn’t have enough of a type of globulin, affecting the strength of your immune system

  • inflammatory conditions

  • delayed post-surgery recovery


Low albumin is considered albumin below 3.4 g/dL. It’s associated with decreased effectiveness of medications used for ulcerative colitis. Low albumin levels may result in complications during or after surgery.

A/G ratio

Normally, the A/G (albumin to globulin) ratio is slightly higher than 1. If the ratio is too low or too high, additional testing must be done to determine the cause and diagnosis. If the ratio is low, it can suggest:

  • autoimmune disease

  • multiple myeloma

  • cirrhosis

  • kidney disease


A high A/G ratio can indicate genetic deficiencies or leukemia. Make sure to discuss your results with your doctor. They may want to do follow-up testing.
