What is this test?

This test measures the amount of alpha-1 globulin, a protein, in your urine. Electrophoresis separates urine proteins by their physical properties so alpha-1 globulin can be identified and measured.

Why might I need this test?

Your clinician may order this test as part of a urine protein evaluation. It may help investigate kidney function, protein loss in the urine, or an unusual protein pattern found through other testing.

How is the test performed?

A urine sample is collected and analyzed in the laboratory. The laboratory uses electrophoresis to separate the proteins in the sample and determine the mass concentration of alpha-1 globulin.

How do I prepare for the test?

Follow your clinician's instructions about when and how to collect urine. In some cases, the laboratory may request a first-morning or timed urine sample, so tell the staff if you received specific collection instructions.

Reference range

Adult: 44-147 U/LN/A

Specimen: urine

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

Frequently asked questions

Does this test diagnose kidney disease?
No. This test is one part of evaluating urine proteins and must be interpreted with other kidney tests, symptoms, and medical history.
Why was electrophoresis used?
Electrophoresis separates the different proteins in urine. This helps laboratory staff identify and measure alpha-1 globulin and evaluate the overall urine protein pattern.
Will I need to repeat the test?
Repeat testing may be needed to confirm an abnormal result or compare it with other urine protein measurements. Your clinician will explain whether follow-up is appropriate.
