What is this test?

This test measures alpha-1 globulin, a protein fraction, in urine collected for 24 hours. Urine electrophoresis separates protein fractions so the amount of alpha-1 globulin excreted over the collection period can be calculated.

Why might I need this test?

A clinician may order this test as part of an evaluation of protein in the urine, kidney function, or an abnormal protein pattern. It may be used alongside serum protein testing and other kidney or urinary protein studies.

How is the test performed?

You collect all urine for 24 hours in the container provided by the laboratory. The laboratory then separates urine proteins by electrophoresis and calculates the amount of alpha-1 globulin excreted during that period.

How do I prepare for the test?

Follow the laboratory's collection instructions, including the starting and ending times and how the container should be stored. Do not change your medications or fluid intake unless your clinician specifically instructs you to do so.

Reference range

Adult: 44-147 U/LN/A

Frequently asked questions

Does this test require a timed urine collection?
Yes. All urine produced during the specified 24-hour period must be collected so the laboratory can calculate the total amount of alpha-1 globulin excreted.
Is this the same as an alpha-1 antitrypsin test?
No. This test measures the alpha-1 globulin protein fraction in urine, not alpha-1 antitrypsin in blood. Although alpha-1 antitrypsin is part of the alpha-1 globulin fraction, the tests are used for different purposes.
What can an abnormal result mean?
An abnormal amount may reflect kidney disease, increased protein loss, or changes in blood protein levels. Your clinician will interpret it with other laboratory findings and your medical history.
