Educational information only. At Precursor, blood testing is requested and reviewed by a clinician and considered alongside your history and other markers, not as a stand-alone diagnosis. Testing is performed in NATA-accredited laboratories to ISO 15189 standards.

What is globulin?

Globulins are a broad family of blood proteins that includes antibodies, transport proteins and enzymes. The globulin value is usually calculated by subtracting albumin from total protein. Because antibodies are part of this group, globulins offer a window onto the immune system as well as the liver.

Why it matters

Globulin is most useful in relation to albumin. The ratio between the two, and the direction each moves, helps a clinician distinguish between liver issues, inflammation, immune activity and other causes, turning two simple numbers into a more informative picture.

What your results can mean

Higher than optimal

A raised globulin can accompany inflammation, infection or increased immune activity. It prompts a clinician to look at the wider clinical picture and, where needed, more specific tests.

Lower than optimal

A low globulin is less common and can relate to immune or protein-loss issues. As always, it is read in context rather than alone.

Reference ranges in Australia

Globulin is reported in grams per litre (g/L) and is typically a calculated value, with laboratory-specific reference ranges. Read your result against the range on your own report and alongside your albumin.

Test your liver with Precursor

Globulin gains meaning alongside albumin and the wider panel. At Precursor it is measured as part of Full Advanced Bloods, a single clinician-reviewed blood draw covering your liver, heart, metabolic, hormonal, kidney, thyroid and nutrient markers together, giving you and your clinician a broad baseline to understand and track.
