What does your blood report say about Globulin? (Globulin Blood Test)

Have you ever had a blood test and got confused when you saw the words and numbers on the report? There are many words like "Total Protein", "Albumin", "Globulin" and many numbers. We can't figure out what these actually mean. So, today we will talk very simply about what "Globulin" is and how it is important for our body.

Simply put, what is this globulin?

Globulins are a type of protein found in our blood. Imagine that our body is like a big country. Then these globulins are the soldiers, workers, and engineers in that country who do various jobs. These proteins are mainly made by our liver and our immune system , which is the system that fights diseases.

These globulins make up about 40% of the proteins in our blood. The other major protein is albumin.

So what service do these globulins provide to our bodies?

These perform several very important functions for our body:

• Fights infections: Like soldiers, these globulins help protect us from disease by fighting germs like viruses and bacteria that enter our bodies.
• Helps blood clot: When you get injured, the blood stops bleeding because it clots. These proteins also help in that process.
• Helps with liver and kidney function: These are also essential for maintaining the healthy functioning of the liver and kidneys, two of the most important organs in our body.

Why is the doctor asking you to do this Globulin Test?

There may be several reasons why a doctor might prescribe this test.

1. As a general health checkup (Screening): As part of your annual health checkup, this test can detect any medical conditions, such as liver problems, early.

2. For Diagnosis: If you have any symptoms, for example, if you suspect a liver or kidney problem, this test can help confirm it.

3. Monitoring: If you already have a disease, the results of this test can help you see if the disease is getting better or worse.

What are the types of globulin tests?

Depending on your symptoms and suspected medical condition, your doctor may order various globulin tests. There are two main types.

1. Total Protein Test

This is the most common test. It measures the total amount of protein in your blood. That is, the sum of two types of proteins called globulins (specifically alpha and beta globulins) and albumin. Alpha and beta globulin levels increase when there is inflammation in the body.

This Total Protein Test is usually performed as part of a liver function test. Your doctor may order this test if you have the following symptoms:

2. Serum Protein Electrophoresis

This is a somewhat specialized test. It mainly measures the level of gamma globulins . Another name for gamma globulins is immunoglobulins . These are the main soldiers in our immune system. These are the ones who directly fight germs that enter the body.

Therefore, this test is performed when there is suspicion of diseases related to the immune system. For example:

• Allergies
• Autoimmune diseases - These are diseases in which our body's immune system attacks our own body. Examples include Lupus and Rheumatoid Arthritis.
• Some types of cancer, for example, multiple myeloma.

How is this blood test done?

This is a very simple procedure. It can be done at your doctor's office, in a lab, or at a hospital. It is usually done by a nurse or a phlebotomist. It takes less than five minutes.

• First, a rubber band (tourniquet) is placed on your arm just above the elbow to make the veins more visible and easier to draw blood.
• Then, the area where the blood was drawn is cleaned with a disinfectant.
• Using a very thin needle, the required amount of blood is taken from the vein into a small vial. Although it feels like being bitten by a small ant, it is not very painful.
• Once the blood is drawn, the band is removed, the needle is removed, and the area is pressed with a piece of cotton for a while.
• Finally, a small plaster is applied to the area.
• The blood sample taken from you will be sent to the lab for testing.

Do I need to prepare anything special before the test?

Sometimes you may be advised to fast for about 12 hours before this test. Your doctor will tell you exactly what to do.

What do the numbers in the report say?

It usually takes a few days for the lab results to come back. Once the results are in, the doctor will explain them to you.

Globulin levels are measured in grams per deciliter (g/dL). Results can vary slightly depending on the methods used by each lab. Therefore, it is best to always get tested by the same lab if you are monitoring your condition.

What is this A/G Ratio?

You may see a value called A/G Ratio in your Total Protein Test report. This is the ratio between albumin and globulin . Normally, a healthy person has more albumin than globulin in their body. Therefore, this ratio is slightly higher than 1.

What does an increase in globulin levels mean?

An increase in protein levels in the blood (hyperproteinemia) can be a sign of a medical condition. However, a single test cannot diagnose a disease . This is only a sign. The doctor will need to perform further tests to make a diagnosis. Possible causes of elevated globulin levels include:

• Autoimmune diseases
• Cancer conditions (e.g. Multiple Myeloma)
• Infections and inflammation in the body

What does a low globulin level mean?

Similarly, low globulin levels can also indicate a medical condition. This also requires further testing. The main contributing factors are:

• Kidney disease: If too much protein is excreted from the kidneys, globulin levels may decrease.
• Liver disease: Since the liver is the main site for making globulin, protein production may decrease if the liver is damaged.

Other special occasions

Can dehydration cause increased globulin?

Yes. When the body's water content decreases, the concentration of the blood increases. Therefore, the globulin level may appear to be higher than it actually is. This value may return to normal when the body's water level is restored by drinking plenty of water.

Do globulin levels change during pregnancy?

Yes. During pregnancy, the total protein level and globulin level increase slightly due to the changes that occur in the body. These levels return to normal after the baby is born. This is normal and there is nothing to worry about.

Finally, globulin is a group of proteins that are essential for the health of our body. This test can provide important clues about the health of your liver, kidneys, and immune system. Remember, don't be alarmed by a low or high value in the report. It only means that something needs to be investigated further. Your doctor will perform the necessary tests and give you the right advice.
