Overview

The Globulin test measures your blood's globulin proteins—a diverse group that includes antibodies, transport proteins, and various regulatory molecules. As part of your immune system's toolkit, globulins help fight infections and inflammation.

Total globulin serves as a screening test. Abnormal levels signal that something warrants investigation, though the specific cause requires additional testing to identify. Elevated globulins often indicate your immune system is activated—fighting chronic infection, responding to autoimmune disease, or producing abnormal proteins in certain cancers. Low globulins may suggest immune deficiency, protein loss, or reduced production.

This test suits Australians with unexplained symptoms suggesting immune dysfunction, those with known liver disease requiring monitoring, and anyone whose routine blood work shows protein abnormalities needing further characterisation.

Symptoms

Suited to people investigating chronic infections, inflammatory conditions, abnormal protein levels on a previous blood test, or monitoring known liver disease. Often assessed as part of a broader liver function or protein panel.

Questions

Globulins are a group of proteins in your blood that include antibodies (immunoglobulins), transport proteins, and clotting factors. Measuring globulin levels helps your practitioner investigate conditions affecting the immune system, liver, and overall protein balance.
Globulin is calculated by subtracting albumin from total protein. It is not measured directly but derived from the two other values. Some practitioners also request serum protein electrophoresis (SPE) for a more detailed breakdown of individual globulin fractions.
No fasting is required. You can eat and drink normally before the test.
Elevated globulin can be associated with chronic infections (such as hepatitis or tuberculosis), autoimmune conditions, liver cirrhosis, and some blood disorders including multiple myeloma. Your practitioner will assess the likely cause based on your overall clinical picture and may request further testing.
The A:G ratio compares albumin to globulin. In healthy individuals, albumin is typically higher than globulin, giving a ratio above 1. A reversed or low ratio (where globulin exceeds albumin) can suggest conditions such as liver disease, chronic inflammation, or blood protein disorders.
Results are sent directly to you via the Bloody Good Tests platform. Share them with your GP or healthcare practitioner for interpretation in the context of your symptoms and health history.

How to prepare

No fasting is required. Drink water as normal.

Let your practitioner know about any chronic health conditions, recent infections, or medications you take regularly, as these can affect globulin levels. A healthcare professional will take a blood sample from a vein in your arm.

After the test

Share your results with your GP or relevant specialist. If your globulin is significantly elevated, your practitioner may request serum protein electrophoresis (SPE) or immunoglobulin tests to further characterise the type of proteins involved. If your globulin is low, further immune function testing may be considered.

Your test results will be available in your private dashboard. If there are any urgent issues, we'll let you know so you can follow up with your health professional.

Understanding results

Globulin is calculated from total protein minus albumin. Results are reported in grams per litre (g/L), with a typical adult reference range of approximately 20 to 35 g/L, though this can vary between laboratories.

Elevated globulin may be associated with chronic infections, autoimmune conditions, liver cirrhosis, or certain blood disorders including multiple myeloma. The albumin-to-globulin ratio (A:G ratio) can help your practitioner assess the balance between these protein groups and narrow down possible causes.

Low globulin may suggest immune deficiency or conditions affecting protein production or loss.

Your practitioner will interpret globulin alongside albumin, total protein, and other relevant markers.

Adam O. ACT

Simple health checks in my control

I didn't know that private blood tests were an option. Tried this platform as the packages suited what I wanted for a good price. Easy to follow instructions, and super quick results. Platform provides more information than my gp's ever have on the tests and what the results meant. Would like more clinics to be able to test at (specifically Capital Pathology) but there is a decent network. Will continue to use.

Calcium Blood Test

"I'm a little biased as I work here! However, I love that The Bloody Good Test tracks my health over time. After turning 40, I wanted to make sure I wasn't going to drop dead from something basic I should have known about earlier. Measuring all my core biomarkers each year gives me peace of mind my health is on the right track"

Frequently Asked Questions

Do I need to book ahead?

Most collection centres accept walk-ins. Some may require a booking - check details when you click on your chosen location.

How do I know if I need to fast?

If your test needs fasting, we’ll include that in your instructions after you order. Fasting usually means no food for 8–12 hours, but water is fine.

What do I need to bring?

Just your pathology referral form (we email it to you)

Can I bring someone with me?

Of course. Just maybe don’t bring the friend who faints at the sight of blood.

What’s a phlebotomist?

They’re the highly trained professionals who take your blood sample - with a steady hand and a sharp needle. They love blood, but don’t worry… they’re not vampires. Just legends who make blood tests quick, clean, and (almost) painless.

What other samples may I need to provide for my test?

Some of our tests include Urine, Stool, Saliva and more. Each test will have a clear description on what sample you will need to give and instructions on how.
