Alpha Globulin, Abnormal — Serum/Plasma Electrophoresis, Mass Fraction

Published: August 9, 2026Updated: August 16, 2026

Measures the alpha globulin fraction of blood proteins using electrophoresis. An abnormal result can reflect changes in inflammation, liver or kidney function, or immune proteins.

What is this test?

Alpha globulin is a group of proteins found in blood. This test measures the amount of the alpha globulin fraction and may be reported as abnormal if it is higher or lower than expected. It is generally part of a serum protein electrophoresis panel.

Why might I need this test?

Your clinician may order this test to investigate an unusual protein pattern, unexplained changes in laboratory results, or symptoms that could suggest inflammation, liver disease, kidney disease, or a plasma-cell disorder.

How is the test performed?

A blood sample is collected, and the liquid portion is separated. The proteins are then separated by electrophoresis, and the alpha globulin fraction is measured or assessed for an abnormal pattern.

How do I prepare for the test?

Fasting is usually not required, but follow your clinician's instructions. Tell the laboratory if you are pregnant or recently received a blood transfusion, because either can affect protein electrophoresis results.

Reference range

Adult: 44-147 U/LN/A

Specimen: serum

No special preparation required. Avoid fatty meals before the test if possible.

Frequently asked questions

Does an abnormal result mean I have a serious illness?
No. An abnormal alpha globulin result is not a diagnosis by itself and can have many causes, including common conditions such as inflammation. Your clinician will interpret it with the other test results and your medical history.
Is this the same as an alpha-1 antitrypsin test?
No. Alpha-1 antitrypsin is one specific protein, while this test evaluates the broader alpha globulin fraction by electrophoresis. Your laboratory report identifies the exact test performed.
Will I need follow-up testing?
Possibly. If the result is abnormal, your clinician may repeat the test, review related electrophoresis findings, or order other blood tests to determine the cause.
